I have 1 Mars Hydro , and a bunch of wayke me leds. Iam switching over to mars anyway. Great lights . I got all mine off amazon. gotta watch some of those Bargin lights, like the plastic ac adapter. wow. Mars is the only way to go!
I bought 4 of the 1st generation white 300 watt really 140 watts. To cool down a tent and try cheap leds from Google. Well about 2.5 years later three and half of the fourth one are dimmer but still burning, They Suck!
