Which T bulb gives off the mist heat - t5,t8 or t12

Because of living in Arizona and growing under lights you can forget cool growing plants. Moving here from New Jersey I lost about half of my orchids because of the heat.

Since I have three shelves on my cart, I will use one with t5 lights for catts., etc and the other two use t8s.
Hopefully this won't be as hot as three shelves using all t12
