Thanks and I have tested the temp of the light on the top and it is comfortable enough that I used the ballast to help germinate seeds.watch for bleaching. there is a specific type of led damage that occurs as well. expresses more like a mutation.
led fixture heat is about 60 / 40 emitters / drivers. larger rigs will be closer to 70 / 30. the heatsinks should pull most of it away from the emitters, and slowly release it. drivers should hit a more or less a constant temp and stay there. the cases are part of the heat sinking in most aluminum case drivers.
good rule of thumb : you should be able to rest your hand on the top side of your fixture / heatsink, and on top of the driver(s), without it being uncomfortable or burning with the rig running at the max.
if you have to pull your hand away cause it is too hot - then there is a problem. either insufficient heatsinking / air exchange / inadequate drivers / poor chipsets or chipset mounts. most times it's combination of factors.
