How serious are you about low heat? If you are then cfls are the low heat option. You can put your own system together with clamp reflectors bought locally. I find 42 watt (actual) cfls the best dollar value.

well heat isnt too big. my limit is around $200-220. my house tho ill need to open a door to let the stale air out .so it will be closed off most of the day. and i don't want the room to get too hot. i figure ill open it at night to not disturb the light cycle. ill have a fan running in it and ill add a box fan at night to push out the stale air. my windows wont open till i replace them. the room is at least 6 foot squared if not more
