But if you use them for 10 minutes it will get really hot in an apartment?
I want to turn on something like this from time to time in order not to use the flash (which can be disturbing to the eyes). Well, I don't think for a quite small room I will be needing 2 x 500 Watts bulbs, I think I can get away with 2 x 250 Watts. I'm not a pro, so I don't have money for L.E.D.
