Hi Denny,
yup its a 0.5% watt LED ,in front of the light is a 1/8 thick frosted acrylic sheet that has been blacked out w/ flat paint with a disc left clear to portray the Moon with a brown paper disc to shade the Moon.....probably more then you wanted to know. It was a lot of fun to make and is designed by a very talented local to me artist named Deb Nicholson.
