I'm thinking about building a shadow box of sorts that will have a vinyl logo on the inside with frosted glass around it. Does that make sense? I haven't decided on the exact depth of the box yet, maybe 3" or so deep. I'd like to back light it with LED's, but I don't have a clue about using them. I was thinking about using the strip type on the inside of the box. Is heat a problem with LED's? Can someone give me some advice about them? Any suppliers that you've used etc.
