I dug this track light out of storage and mounted it above the layout. I did this for several reasons. First it lights the layout more evenly. Second I can use my GE Reveal light bulbs exclusively for layout lighting. These bulbs mimic natural daylight and show colors more accurately than normal bulbs. However they also use a lot more power and give off more heat than CFLs. Now I can covert the other lamps in the room to low-power CFLs and use the reveals only when it's time to run trains. Third, this also giver me a nice, permanent light source for photos.
