I have a light box in the center of the room ceiling with florescent bulbs...2 about 4 ft long... They have lasted for years with changing only once and don't give off heat. I also have a large double window across the room and a table Ott light if I need concentrated light for a particular project. I believe good lighting is so essential. I have never regretted using florescent bulbs. My room is painted a creamy yellow so I'm sure that helps as well.
