Lighting vs. heat.... my biggest problem!

Nothing has given me more problems than this. The closet will heat up like a friggin oven, i remove lights and now the plants aren't illuminated well enough. All the fan tricks in the world won't help either... cracking the door.. nope. What are ya's thoughs on this?

Closet... 6 feet long, 3 wide, 10 high

15O WATTS = 85 deegres +

Swamp cooler didn't help

what type of light? if its a HPS you can run a cool tube. if your running CFL then you just need more airflow.

whats your ambient temp like
