ah...sounds bad. what type is it? if it's putting off a lot of heat it might be a halogen flood lamp.
go down to walmart or something and pick up some CFLs
they have 23watt 6500k daylight CFLs, get some clamp reflectors too for easy installation. also get a fan running in there it will strengthen up your stem and provide fresh air. you can place the CFLs fairly close too, within inches for best results.
