The ceramic handles more heat, giving steadier color and a CRI of roughly 80 to 96. CDM is Philips' original name for it, and LEC is one brand's trademark.\u003c\/p\u003e\n    \u003ch3\u003eCMH vs HPS?\u003c\/h3\u003e\n    \u003cp style=\"text-align: justify;\"\u003eHPS gives a narrow orange-red spectrum at higher wattages, while CMH spreads output across blue, red and some UV. A 315W CMH draws about 340W, so it adds less heat per fixture than a 600W HPS. Many growers flower under 3100K CMH.\u003c\/p\u003e\n    \u003ch3\u003eCMH bulb for flowering or veg?\u003c\/h3\u003e\n    \u003cp style=\"text-align: justify;\"\u003eUse 3000 to 3200K for flowering and 4000 to 4200K for veg. In our 315W lamp test, every top-three PAR result came from a warm 3000 to 3200K lamp. The 4200K lamps render color better, which helps in veg rooms and when scouting for pests.\u003c\/p\u003e\n    \u003ch3\u003e315W CMH coverage?\u003c\/h3\u003e\n    \u003cp style=\"text-align: justify;\"\u003ePlan on about 12 square feet per 315W fixture. Endomaxx rates its 315 at 12 square feet from 30 inches above the canopy, roughly a 3.5 by 3.5 foot area. For a 4x4 or larger space, run two 315W fixtures or step up to a double-ended CMH setup.\u003c\/p\u003e\n    \u003ch3\u003eHow long do CMH bulbs last?\u003c\/h3\u003e\n    \u003cp style=\"text-align: justify;\"\u003eRated life runs from 10,000 to 30,000 hours, depending on the lamp.

Grower's Choice rates it for open or enclosed fixtures and for any burning position. Maximum base temperature is 250°C and the bulb itself tops out at 350°C. The company says a phosphor coating on the outside of the arc tube shapes its spectrum. That coating is what pushes output toward the warm end.\u003c\/p\u003e\n\u003ch2\u003eHow this 315W CMH bulb did in our own lamp test\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eIn our ten-lamp CMH comparison it finished fifth on summed PAR, ahead of both Ushio lamps and several discontinued names. Its UV reading was the lowest of the group, though, so it is not the lamp to pick if short-wave light is the goal. That is worth knowing, because the maker's own copy leans on UV and far-red content. What it does well is photons per dollar in a warm, flower-friendly spectrum. At this colour temperature it sits in the bloom and transitional range and can still carry a veg room in a pinch. In a 4x4 tent, most growers start one lamp around 18 to 24 inches above the tops and come down after the stretch. Pair it with a low-frequency CMH ballast, since standard HPS and MH ballasts will not drive it. A red-enhanced 3K-R version exists in the same range for rooms that want more deep red late in flower. The cooler 4200K lamp from the same line is the better pick for dedicated veg. It is sold as a bare lamp, so the reflector, socket and ballast come separately.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e570 µmol\/s Photon Flux:\u003c\/strong\u003e A published PPF figure lets you plan canopy intensity instead of guessing from lumens.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e37,000 Lumens at 120 lm\/W:\u003c\/strong\u003e High efficacy means more light per watt and less heat for the same output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFifth of Ten in Our PAR Test:\u003c\/strong\u003e It beat both Ushio lamps on summed PAR in our side-by-side comparison.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3100K Bloom Spectrum, CRI 90+:\u003c\/strong\u003e Warm, broad output supports flowering and keeps plants easy to read under the lamp.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e15,000-Hour Rated Life:\u003c\/strong\u003e Rated at ten-hour starts, it covers years of flower cycles before replacement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePGZX18, Any Burn Position:\u003c\/strong\u003e Fits standard single-ended 315W reflectors, open or enclosed, in any orientation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background-color:#333; color:#fff;\"\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003ePart Number \/ SKU\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eCMH-315W\/931\/PGZX18\/HO \/ GC315W3K01\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eLamp Type\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eCeramic metal halide (CMH\/LEC), single-ended\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eWattage\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e315W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eColor Temperature\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e3100K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eGrowth Phase\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eBloom \/ transitional\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eLumens @ 100 hrs\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e37,000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eEfficacy\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e120 lm\/W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eCRI\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e≥90\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003ePPF\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e570 µmol\/s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eRated Life\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e15,000 hours (10-hour starts)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eBase\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003ePGZX18\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eLamp Voltage \/ Current\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e100V \/ 3.15A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eMin.

Growers run it over mother plants, fresh clones and young veg, and in single-lamp tents that go start to finish. The blue-rich output tends to keep internodes short and branching tight before flip. That high colour rendering also makes scouting easier, because leaf colour under it looks close to natural. Hang it higher over fresh cuttings and lower it as the canopy thickens and roots fill the pots. In our own ten-lamp CMH comparison it placed last on summed PAR, and its UV reading was the second lowest. The whole field sat within a narrow band on PAR, so last place still means a usable lamp. It is not the pick for maximum photons in flower, where the warm lamp in the range does better. Plenty of growers run one of each in a two-light room, which blends the two spectra without swapping bulbs at flip. Drive it with a low-frequency CMH ballast, since HPS and MH ballasts will not run it.

Burning position is universal, so it can hang vertically, horizontally or at an angle. A hot restart takes 6 to 8 minutes. Maximum base temperature is 190°C and the bulb can reach 400°C.

At this colour temperature it leans warm, which suits flowering while still carrying transitional growth. The medium base looks like a household socket, but this is a ballasted HID lamp. It will not light in an ordinary lamp fitting, and it needs a CMH or pulse-start metal halide ballast built for this wattage. Hang it closer than a big lamp, then raise it if the top leaves start to bleach or curl. That lower output is the trade-off for less heat and a smaller power bill. It will not carry a full flowering canopy on its own. For a 4x4 tent, the SunPulse 315W lamp is the better choice, and that lamp placed second of ten in our own CMH test. Many growers search for this as a 150 watt metal halide lamp, which it is, with a ceramic arc tube instead of quartz. The rated life is shorter than most 315W lamps, so plan on replacing it sooner.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e250 µmol\/s PPF:\u003c\/strong\u003e A published photon figure helps size it for a shelf or small tent.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e15,750 Lumens at 105 lm\/W:\u003c\/strong\u003e Efficient output for its wattage keeps heat low in tight spaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3200K Warm Spectrum:\u003c\/strong\u003e Bloom-leaning light suits flowering and transitional growth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eE26 Medium Base:\u003c\/strong\u003e Fits ballasted HID fixtures built around a medium socket.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Burning Position:\u003c\/strong\u003e Mounts vertical, horizontal or angled without losing performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen or Enclosed Luminaires:\u003c\/strong\u003e Runs in open reflectors or sealed fixtures.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%;

Most growers use it to replace a sodium lamp in a mogul reflector they already own, since the socket format is the same. Check that the socket and hood are rated for a lamp of this wattage before you swap anything. A reflector is not part of the kit. A lamp this strong wants real mounting distance, so start high and come down slowly while watching leaf temperature. The lower dimming steps help during the first week of flip, or when a new batch of clones goes under it. Allstate also describes the same ballast for HPS and MH use, which leaves room for a sodium lamp late in flower. Mount the ballast off the floor and away from the canopy so its heat stays out of the room air. One wiring requirement decides whether this kit fits a room. It runs on a 240 volt circuit, so a standard 120 volt wall outlet cannot power it.

It plugs into an ordinary outlet next to fans and a heat mat without tripping the breaker. In a small grow tent it works as the main light over a few plants. It also fills gaps as a side light beside a larger fixture. Propagation shelves and mother-plant corners suit it too, because young plants do not need heavy intensity. Start it high over seedlings and cuttings, then lower it as they harden off and leaves thicken. The wet-location rating means it can hang over a misted bench or in a humid hobby greenhouse without worry. What it will not do is carry a large flowering canopy on its own. For a full flower room, the Endomaxx 315 or a larger fixture is the better call. Helios publishes no colour temperature or photon figure for the stock lamp, so a PAR meter is the honest way to set hang height. The cord choice decides the plug, not the ballast, since both versions share the same wide-voltage driver.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e150W Ceramic Metal Halide:\u003c\/strong\u003e A low-wattage CMH lamp gives small spaces broad-spectrum light without a big heat load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1.38A at 120V:\u003c\/strong\u003e The low draw shares a household circuit with fans and heaters comfortably.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWet-Location and Greenhouse Rated:\u003c\/strong\u003e It can hang over misted benches and in humid hobby greenhouses.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUL Listed E475228:\u003c\/strong\u003e A recognised listing for the USA and Canada covers the full fixture.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug and Play:\u003c\/strong\u003e Lamp, ballast, cord and hooks arrive together, ready to hang and fire.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e30,000-Hour Lamp Life:\u003c\/strong\u003e Long rated life suits propagation areas that run lights most of the day.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%;

Greenhouse air runs humid, benches get hosed down, and condensation drips off glazing on cold mornings. A fixture listed for those conditions keeps an inspector and an insurer satisfied. As supplemental light it extends short winter days and fills cloudy afternoons, so it suits a bench of starts or a hoop house of transplants. Hanging it higher spreads the footprint, and lowering it tightens the pool for a single bench or a young crop. Its light weight makes it easy to hang from greenhouse purlins that were never meant to carry heavy HID hoods. Bigger houses already run the 208, 240 or 277-volt circuits it wants. It will not run from a household outlet, though, so a hobby greenhouse on a single standard circuit needs the smaller Endomaxx 150 instead. Helios does not publish a colour temperature or a photon figure for the lamp, so plan intensity with a PAR meter after hanging. A replacement lamp is a standard ceramic metal halide part, which keeps the running cost predictable.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e38,700 Initial Lumens:\u003c\/strong\u003e The 315W ceramic lamp gives a greenhouse bench strong supplemental output for its wattage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWet-Location and Greenhouse Rated:\u003c\/strong\u003e Humidity, washdowns and condensation are part of its listed operating environment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUL Listed E475228:\u003c\/strong\u003e The USA and Canada listing matters when a commercial house faces inspection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e200-277V at 98% Power Factor:\u003c\/strong\u003e Clean power draw on commercial circuits keeps multi-fixture installs efficient.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnder 10 lbs, Plug and Play:\u003c\/strong\u003e Lamp, ballast, cord and hooks arrive together and hang easily from light framing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e30,000-Hour Lamp Life:\u003c\/strong\u003e Long rated life cuts lamp changes in greenhouses that run supplemental light for months.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%;

The lamp is 394 mm (15.5 in) end to end, with a light centre length of 195 mm and a 61 mm bulb diameter. Growlite rates it for open or enclosed fixtures and any burning position. That is a useful combination for a DE lamp. It means the lamp can run bare in an open double-ended reflector or behind glass in a sealed hood. Growlite's 315W CMH electronic ballast was developed alongside its lamps, although any C182\/O-rated CMH ballast will drive it.\u003c\/p\u003e\n\u003ch2\u003eWhere a full spectrum ceramic metal halide lamp like this fits\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eAt this colour temperature the lamp sits in the transitional band, balanced enough to run one spectrum from veg to harvest. That suits a single-light room where swapping lamps at flip is more hassle than it is worth. Growers who want the most bloom intensity usually pick a warmer lamp near 3000K instead. Hang it higher over young plants and lower it in stages as the canopy fills in and the stretch ends. The double-ended format needs a matching DE fixture, so it will not thread into a mogul or PGZX18 socket. Check the socket spacing on your fixture before ordering replacements, because DE lamp lengths differ between wattages and brands. Like every ceramic metal halide lamp, it emits UV, so avoid looking at the arc and wear CMH-rated eyewear when working close. Handle the quartz with gloves or a clean cloth, since skin oil on the glass shortens lamp life. Growlite does not publish a UV figure for it, and the lamp was not part of our own ten-lamp CMH test.

A ballast limited to the two household voltages cannot connect there without a step-down transformer, and this one skips that part. Mount it remotely, outside the reflector and off the canopy, so its heat stays out of the air you are paying to cool. The manual asks for at least six inches between ballasts, and it wants them kept away from gas or electric heaters. Never plug or unplug the lamp cord while the ballast is powered, since arcing at a live connector can damage the lamp and ballast. It is rated to run from -13°F to 122°F ambient, which covers a sealed room in summer or an unheated greenhouse bay in winter. Because it strikes both lamp formats, you can move from a mogul-base lamp to a double-ended one without changing drivers. The limits are real, though. It will not run HPS, standard metal halide, or any other wattage, and Growlite publishes no dimming or boost setting. Intensity is managed with hang height instead, usually starting higher over seedlings and dropping as the canopy fills in. Neither Growlite nor its retailers publish a UL or ETL listing for it, so rooms that need an inspector's sign-off should confirm that first.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Sensing 120-277VAC:\u003c\/strong\u003e The ballast reads the supply on its own, so one unit covers residential and commercial circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSE and DE 315W CMH Lamps:\u003c\/strong\u003e It strikes both lamp formats, which keeps the fixture choice open when a room gets refitted.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1.14A Draw at 277V:\u003c\/strong\u003e Lower current per fixture lets more lights share a single lighting circuit in a large room.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeven Built-In Protections:\u003c\/strong\u003e Short, open, end-of-life, hot-start, ignition, thermal and voltage faults shut it down before damage spreads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSealed, Quiet Housing:\u003c\/strong\u003e A sealed case and quiet operation suit rooms where people work beside the lights all day.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-Year Warranty:\u003c\/strong\u003e Growlite covers the ballast for three years, and a 6 ft cord is included.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%;

It runs at a nominal 100V and 3.15A on an ANSI C182\/O-rated ballast. The lamp measures 292 mm (11.5 in) overall with a 178 mm light centre length and a 121 mm (4.75 in) bulb diameter. Growlite rates it for open or enclosed fixtures and a universal burning position. That envelope is much bigger than a PGZX18 lamp. It is sized like a standard mogul HID bulb, so it sits where the old lamp sat in a single-ended hood. Growlite also makes a slimmer T15 mogul version and a double-ended lamp in the same line.\u003c\/p\u003e\n\u003ch2\u003eUsing an E39 mogul base CMH lamp in an existing reflector\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe mogul base is the whole point of this lamp. It screws straight into the socket of a single-ended HPS or MH reflector, so no socket adapter is needed. The socket is only half the job, though. It still needs a ceramic metal halide ballast, because a magnetic or digital HPS ballast will not drive it properly. Before you swap it in, confirm the reflector's socket and wiring are rated for a lamp of this size and heat. At this colour temperature it sits in the transitional band, so one lamp can carry a room from veg through harvest. Growers chasing maximum bloom output tend to run a warmer lamp near 3000K instead. Start it high over young plants and bring it down as the canopy fills and the stretch finishes. Like every ceramic metal halide lamp it emits UV, so wear CMH-rated eyewear such as Summer Blues Optics glasses when working under it.

style=\"text-align: justify;\"\u003eThe C1 is an all-in-one 315W ceramic metal halide system from Solis Tek, with reflector, digital ballast and lamp in one box. Overall it measures \u003cstrong\u003e16 x 25 x 5 in\u003c\/strong\u003e, the reflector is 16 x 10.5 x 5 in, and the ballast is 8 x 6 x 5 in. The ballast accepts either \u003cstrong\u003e120V or 240V\u003c\/strong\u003e input. It is a low-frequency digital unit carrying the brand's Ignition Control, SenseSmart and Soft Start circuitry. Solis Tek pitched those three as a gentler, more stable strike, which is easier on a ceramic arc tube than a hard start. It runs 315W ceramic metal halide lamps only, so HPS and standard MH bulbs are off the table. Fixtures can be daisy chained, up to \u003cstrong\u003efour units on 120V\u003c\/strong\u003e or \u003cstrong\u003eeight on 240V\u003c\/strong\u003e.

As supplemental light over an existing greenhouse crop, one fixture can stretch to 5 x 5 ft or more. A Solis Tek 315W CMH lamp comes in the kit, and the reflector carries a mirror finish.\u003c\/p\u003e\n\u003ch2\u003eRunning a ceramic metal halide complete fixture in a tent or small room\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eA small flower tent is where this fixture makes the most sense as the only light. The shallow hood leaves more working height between lamp and canopy than a tall parabolic reflector would. Most growers start a single CMH about two feet above the tops and adjust from leaf response, watching for bleached tips. On the very first strike, let the lamp run continuously for at least fifteen minutes so it beds in properly. Drawing roughly half the wattage of a 600W HPS, it adds far less heat, so a modest exhaust fan usually keeps up. Ceramic metal halide also renders colour naturally, which makes scouting for mites and deficiencies easier under the lamp. If you swap lamps later, a lamp near 3000K leans toward flower, while a 4000K-plus lamp favors vegetative growth. Daisy-chaining lets one outlet feed a short run of fixtures. The unit cap exists because every fixture on that chain shares one circuit, so plan the breaker before adding lights. It came out of the Solis Tek digital lighting line, the same family as the brand's digital HID ballasts. No current manufacturer spec sheet is available for the C1, so weight, cord length and warranty terms are left off rather than guessed.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete 315W System:\u003c\/strong\u003e Reflector, ballast and lamp arrive together, so setup comes down to hanging, plugging in and striking.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow-Frequency Digital Ballast:\u003c\/strong\u003e It drives the ceramic arc tube with Ignition Control, SenseSmart and Soft Start built in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDaisy Chain Ready:\u003c\/strong\u003e Up to four fixtures on 120V, or eight on 240V, run from one supply line.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow 5-Inch Profile:\u003c\/strong\u003e A shallow hood keeps more working height between the lamp and the canopy inside a tent.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible Coverage:\u003c\/strong\u003e Plan on 3 x 3 ft indoors, or 4 x 4 ft as the primary light in a greenhouse.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMirror-Finish Reflector:\u003c\/strong\u003e The polished surface throws light down onto the canopy instead of absorbing it.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%;

It sits on a PGZX18 base inside a clear, double-envelope T12 bulb that measures 193 mm end to end. Ushio rates it for open or enclosed fixtures, burning anywhere from base-up to horizontal. The ballast match is an ANSI C182\/O-rated ballast or an electronic CMH ballast. After a power cut, give it 6 to 8 minutes to cool before it will restrike.

It finished seventh of ten on summed PAR, so it was not the brightest lamp we tested. The spread from first to last on PAR was under 16%, though, so the photon gap is small. That trade is the reason to pick it: close to the leaders on photons, with more of the short-wave band growers chase late in flower. At this colour temperature it sits in the bloom and transitional range, warm enough to carry a crop from flip to harvest. Over a 3x3 or 4x4 tent, most growers start it around 18 to 24 inches above the canopy and lower it once the stretch ends. Open reflectors are fine here, because Ushio rates the lamp for open and enclosed fixtures alike. Drive it with a low-frequency CMH ballast, since a standard HPS or MH ballast will not run it. It is a lamp only, so the socket, reflector and ballast all come from elsewhere. Our UV figure is relative within the CMH class and came from one test rig, not a lab sphere.

That is why growers run it in veg rooms and in single-lamp tents that carry plants from start to finish. The blue-rich output tends to keep internodes tight and stems thick under a young canopy. Its high colour rendering also makes it the easier lamp to scout under, because leaf colour looks close to daylight. Hang it higher over fresh clones, then bring it down as roots take hold and new leaves harden off. In our own ten-lamp CMH comparison it placed ninth on summed PAR, and its UV reading landed in the lower half of the group. So it is not the lamp to pick for maximum photons in flower. Switch to the warm HiLux Gro at flip if you want more output and more UV, or run one of each to mix spectra. Drive it with a low-frequency CMH ballast, since standard HPS and MH ballasts will not run it. It is sold as a lamp only, with the socket, reflector and ballast sourced separately.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eCRI \u0026gt;95 Daylight Rendering:\u003c\/strong\u003e Leaf colour reads true under the lamp, which makes deficiencies and pests easier to spot.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e520 µmol\/s PPF:\u003c\/strong\u003e Ushio's published photon output keeps a veg canopy growing at a steady pace.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4200K Veg and Full-Cycle Spectrum:\u003c\/strong\u003e Blue-rich light supports compact structure through vegetative growth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e15,000-Hour Rated Life:\u003c\/strong\u003e Long rated life on ten-hour starts carries many veg cycles before replacement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePGZX18, Open or Enclosed:\u003c\/strong\u003e The standard single-ended 315W base fits common CMH reflectors either way.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatched 3000K Sibling:\u003c\/strong\u003e The warm HiLux Gro lamp uses the same base and ballast for an easy swap at flip.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background-color:#333; color:#fff;\"\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eModel \/ Product No.\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eCMH-315W\/942\/AGRO \/ 5002537\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eLamp Type\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eCeramic metal halide (CMH), single-ended\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eWattage\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e315W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eColor Temperature\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e4200K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eGrowth Phase\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eVegetative \/ full-cycle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eLumens @ 100 hrs\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e32,000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eEfficacy\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e100 lm\/W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003ePPF\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e520 µmol\/s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eCRI (Ra)\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u0026gt;95\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eRated Life\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e15,000 hours (10-hour starts)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eLamp Voltage \/ Current\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e100V \/ 3.15A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eStarting Current\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e4.7A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eMin.

DLI rates its hemispherical reflectance at \u003cstrong\u003eover 95%\u003c\/strong\u003e. Rated power is \u003cstrong\u003e340W\u003c\/strong\u003e at 50\/60 Hz with a power factor of 0.98 or better. Maximum current is \u003cstrong\u003e3.2A on a 110V line\u003c\/strong\u003e, typical draw is 1.4A at 240V, and the high-voltage version pulls about 1.0A at 347V. Inrush current peaks at 40A or less.

Control is on\/off through DLI's DLM-4 zone controller, with an RJ12 connection kit in the box and an IP65-rated controller port. An improved heatsink keeps the driver cooler, and an LED indicator reports status and error codes.

Every inch the fixture does not take up is an inch between the lamp and the tops, which matters in basements and converted bedrooms. Retailers put its footprint at roughly four by four feet for a single fixture. DLI designed the reflector wide, for small rooms or for mixing with sodium and UV fixtures in a larger layout. Level each fixture with the built-in bubble before the first strike, because a tilted reflector throws a lopsided pattern across the canopy. The zone controller lets a whole row switch together, and the diagnostic light tells you which unit faulted without climbing a ladder to guess. Given that inrush figure, avoid striking a full row on one small breaker at the same moment. There is no dimming beyond on and off, so intensity comes from hang height. DLI does not publish a photon or efficacy figure for the fixture, so none is quoted. It is also heavier than most 315W fixtures, so check the hanging points in a tent frame.
