I am still amazed how much a white wall gives you back light. I use a closet for my bench and have a 4' double tube f40CW fixture hung over the bench, with my round magnifier I am blinded....the white wall at the back eliminates shadows, and very little heat. The worry I have with LEDS is color temp...unless you get the $$$ ones they can really be blue toned...which could get you into paint color troubles....I use the same CW bulbs to work and paint. Color inspection is done outside in the sun....as its bright here at noon!!
I also prefer to shoot most photos outside with fill flash in the bright sun...lotsa light and sharpness follows
