Thanks Joe! The lights in the display cases are dimmable LEDs. I'd say they are on for a total of about 4-6 hours a week in an otherwise completely dark room. They don't put off any heat and have low UV radiation. The lights in the shadow box displays are LED light tape strips. I installed them on the inside of the box behind the frame to give the uniforms sort of a halo effect. They look awesome when the room is dimly lit. I've been contemplating a future article for my site on how to build the shadow displays.
