You've addressed the issue of the drivers failing due to moisture, but not the fact that the LEDs burn out. And I had an 8" fan blowing cool air across the surface of the glass of my Mars II 1200w at all times during lights on, plus a top quality German-made 4" extraction fan running 24/7, and another 6" fan blowing across the canopy of the plants.
Temperatures reached 85F MAX, most of the time they were in the 70s, I know this because I run a humidity/temp gauge in the tent with a memory setting.
What other lengths could I have gone to in order to keep the light cooler and prevent this issue from happening? Most people wouldn't have bothered with the fan blowing air over the panel, either.
Imagine my disappointment when I found so many burnt out LEDs the other day, after approximately 5 months of use.
I have had no problems with my lights but I use no tent of any kind, therefore no humidity build up, no excess fan use. Is it possible with all you have drawing the heat out of the tent that your smaller cooling fan inside the light can't pull enough air in?
