Best lights for low temps in small bonsai mother cab

Hello,

I'm hoping to keep a mother and some clones in a small cab 50cm H X 40CM D X 60cm W .

Its pretty warm in there already and ventilation will only be via opening the door and mini desk fan.

What would be the best lights to use to keep temps down and keep the mammy and baby girls doing OK.

Cheers

I would have to recommend CFL's They are reasonable in Temperature yet still functional.

if you can somehow add 2cm on the width, you could use 18w fluro tube shoplights. theyr great for your purpose, much less heat than cfl's. i have used them for years to grow bonsais

T5's are the obvious answer.

T5 .........

Why don't you upgrade your ventilation a bit just to be safe if its already hot with no lights? Definitely CFL, LED, or t5's though.
