I have cheap shop lights in my brewing area and plan on installing LED lighting once it finally comes down in price. For now I just use soft white fluorescent tubes and put old dress shirts on my carboys to keep the light out.
Incandescent lights (plain old light bulbs put out better light than any of the fluorescent types. The down side on these though is about to be availability. The last US plant making them (and any other light bulb in the US for that matter) is closing down this year.
I do alot of brewing work in my basement and the lighting sucks in general but the fermanting room is an old cellar which is always dark and always at about 65 ish. looking at buying rail led light system for the work area.
