Yes they do put out heat, but you can put them several feet away from the work, and Im sure you can buy smaller watt lights, this was a elcheapo from WalMart.I like haveing them back a bit as it gives a nice white light without too much glare. I have since filled the bottom base with sand and it is very stable.
Im setting mine on the shelf above my grinders so it's about 2' above my head, this seems to be the best distance for mr, and with it angled at the platen I dont really notice the heat as much, but it is cold here now, might make a big diffrence in summer!
God Bless
