My friend has a sun system LEC 315, he loves it.

I think i read somewhere people using old magnetic ballasts to power CMH's I think the technology is way overpriced.


If you do your homework you will find that all this equipment comes from china, and you are paying double to triple the price for a sun system sticker and a company to complain to if it breaks.

I know its a roll of the dice ordering stuff from china, but Alibaba.com has CMH's direct from the manufacturer for half price. They look identical too.

I don't own a 315 but I like the sun system reflector with vertical bulb

I like the growers choice. Decent price and good build quality. They do need to get a controller system going for them, the last time I checked they didn't have one.

I bought three chinese all in ones, topogrow brand, and one ceramic science ballast + ushio bulb. The ceramic science + ushio looked a lot brighter than the chinese all in ones. But when I swapped the bulbs, they lit right up.

So i think the stock bulbs are not great.

Thinking of going Growers Choice or Sun System only ones ive seen that people are migrating to with much sucess, GC just dropped a 1000 DE CMH recently so that one should be one to look for

I own 9 of the 315 LEC Sun System diamond series and I would totally recommend staying away from this particular model. I have 9 of them (240v model) and its really cool that you can daisy chain them but, also can be a HUUUGE pain in the ass when you run into issues with one. I have 3 of them hooked up to each 240 and then those are all wired into a time clock and then that is wired back into a 2 20 amp pull breaker. And one of my lights either has a dud ballast, bad connector, pinched wire etc.. because once or twiceish a week they trip when theyre supposed to turn on. This has been happening for around 2 months now and I still havent been able to pinpoint exactly which one it is, I also havent really tried too too much considering its only once or twice a week when my lights come on. Im pretty much always home when they come on, so it hasnt been the biggest issue. Anyways I contacted sun systems and they said theyll swap the one out no problem, too bad its not the easiest problem to pinpoint because it doesn't happen too frequently and I'm constantly perpetuating a harvest so I cant exactly take my lights out one by one and fire each one individually til one trips. I know it doesn't sound that hard to do but, its very tedious when you have to wait 10 minutes in between turning off/on cmh (not supposed to keep turning them on and off) and the problem doesnt happen everytime they fire.


Tldr: Anyways here I am 3 months later still experiencing electrical problems with my sun systems after paying near $4,000 for the units and havent received any help to troubleshoot except for them trying to tell me I dont have them wired properly. ( I 100% have them wired properly my best friend is an electrician and set everything up)

I like growers choice. Cheap and that 3kr bulb has a killer spectrum

I just ordered two of the GH 630 watt units. I requested 2-3000K Red lamps and 2-4100K lamps. Ill mix them in each unit


Over 1000 bucks for 2 lights, but the dimable and super lumen settings make this an awesome light
