Hot is right! But over 60C? I found some chart online that claims average t5 bulbs to output 80% power at 55C. I am going to do an experiment with cooling the top to see how that effects the bottom. (Heat ought to flow from high temperatures to low temperatures).
I think that I may need to buy the URI t5 V-HO
bulbs since VHO
is designed to run even hotter than HO
. According to the chart I found, t5 HO
bulbs peak at 35C. I cant seem to find anything for t5 VHO
bulbs since they seem to be new and controversial.
I will keep you guys up to speed with what I find.
I scrapped the variac idea as it didnt help heating much.
