Ay carumba... In my 2x2 x 4 tent I have 4 26w cfl and a 75 true watt apollo LED... I'm in veg so this is sufficient light for the space.
I popped in my 150 HPS in place of the LED and temps are off the charts. about 10 degrees above ambient. They were 4 degrees above ambient. Even with my 180 cfm fan on full it's still 82 in there... Not terrible, but not great.
Does anyone have a PARW or Umol test of the mars lights?
Edit... Stupid me.. I just did what I call the Better Crocker Easy Bake Oven.. My vent was disconnected to the other room so the room the light is in just heated up to 79... Hot air in, hot air out...
I still wish LED shopping was easier
I've looked at every piece of crap LED on the market tonight and in the back of my head I know my 150 hps is better than most of them..
