Works Review by Nick

Overall Rating

Conversion is one of the best I've purchased so far. The only problem I've had is the ballasts do not work with the 240 so well. My bulbs fizzled after 7 minutes. I gave it a half hour to cool the bulbs down, and plugged into 120v on 30 amp circuit and then there were no problems. Works every time. I've purchased at least 10 so far and will purchase more. I'm using old hoods and turning xxl hoods into powerhouse lights. With the Phillips 4200 and 3200, better in my estimation than the phantoms using same bulbs. (Posted on 6/15/2017)

Terrific bang for buck Review by MedVer

One of these paired with a 600w HPS
Better overall quality and roughly same quantity of tomatoes as two 600HPS

315 LEC = 600 HPS all day Review by Bud Weaver

Overall Rating

I wasted so much time and money. [email protected] 315 will do a 3x3 area no problem you can strech it to do a 4x4 area however best results are achieved with a bulb every 3' on center. Every bit of floor space will be usuable. Best light available for indoor horticulture. Use 4200k for veg or full spectrum growing or dense up the flowers and bloom with the 3100k.

Small growers dream!! Review by True Dankster

Overall Rating

This set up is awesome! These lil guys will blind you and put off crazy light. You can save so much money between the lower wattage of the 315s and the substantial heat reduction allowing your AC to work easier. I have low ceilings in an attic room and I've had to run only hooded and vented lights hps either 4 600s or 2 1000s and a 600 were all I could cool. I have 5 315s of these going with a 600 all bare bulb with an 1800 split unit cooling things more than adequately. I'll be replacing my 600 with 3 more 315s and will have a total of 8 in that space. I have mine in simple batwing reflectors which are hanging right up against the ceiling off their hangers. I have no worries about the heat at all - these babies are a total game changer. More light exposure and less heat to battle and from what I can tell so far little to no loss in density or yield. Two or three of these bare bulb in a tent would rock. I really think these are the future for the small grower dealing with tight spaces and heat issues, they solved my issues and I'm very happy with the results - that perfect curve on the light spectrum shines through;-) (Posted on 4/7/2017)

quality product Review by thx1138

Overall Rating

This ballast is quiet, well built, and partners very well with the new sun system reflector. These two together with the Philips bulb (3100k) have made my setup very efficient, and compared to regular hps and cob leds, my growth rate far better. I am looking at plants that would be at the 5 week stage under Cree cob leds, and these plants are only at week three under this setup (6 under one 315 watt LEC with this ballast and the reflector noted).
I am vegging under the Philips 3100k and they love it. (Posted on 11/9/2016)
