California LightWorks SolarXtreme 250: Small, Simple, Driverless
The SX-250 is California LightWorks' plug-and-play light, built for one tent and a grower who wants no settings to learn. It draws 200W with a maximum of 1.6A at 120V, so it shares an outlet easily with fans and a filter. The chip-on-board design runs on direct AC drive, which means there is no external driver in the circuit. Spectrum is the fixed Optigrow blend, built from Osram white and deep red diodes and tuned by CLW for bloom. Retail listings put light at about 500 PPFD at 18 in and 800 PPFD at 12 in below the fixture. The housing is only 8.5 x 8.5 x 4 in and weighs around 6 lb. Heat output is listed at 640 BTU, low enough for a closet tent with modest exhaust. Coverage is listed as 3 x 3 ft for both veg and flower. It is made in the USA and ETL listed, with an 8 ft power cord in the box. California LightWorks backs the SolarXtreme series with a 3-year warranty and a 90-day money-back guarantee.
Where a COB LED Grow Light This Size Makes Sense
A cob led grow light concentrates its output in a tight point, which is both its strength and its limit. The center of the tent gets strong light, while the corners fall off faster than under a wide bar fixture. Retail guidance puts it five to six feet above seedlings and young veg, then twenty to thirty inches in bloom. Lower it slowly after flip, and watch the tops closest to the center first. The fixture has no dimmer. Height is your only intensity control. That makes it a good fit for a 2x2 or small 3x3 run by someone who values simplicity over tuning. It also works as a side light in a larger room where one corner stays shaded. Growers who want to change spectrum between veg and flower should look at the SolarSystem series instead. This listing is the standard household-voltage version, so a 240V room needs the other model. The video below shows the fixture and its footprint in a real tent.
