    LED question

    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.

    Thanks

    John,
    In one of my many carriers I sold sign for commercial building the lighted kind that you see on the outside of building that are back lite so you can see m at night. I the old day they always used florescent tubes but now they all use leds. The last longer are easier to install and far less cost. I think if they work for commercial signs they would be fine for your use.

    I haven't used any backlighting in a project yet, but have been checking out some of what I'm seeing on the Vectric PhotoVcarve forum. Here are links to a couple of solutions.

    The led strips work really well, can cut them every 3" or so, max length of about 16' for a typical strip. They put off little to no heat. I buy them on amazon or ebay (have had wiring issues with the ones from ebay), but recently started buying from this place. https://www.superbrightleds.com

    They are located in the St. Louis, MO area, I've been happy with their products so far.

    For what it's worth, I've got a strip of leds on the back of my television for ambient backlighting. Uses very little energy and runs off a usb out on the tv. No discernible heat at all.

    I ordered and received some tape, rrremote control drivers, and some wall-wart power supplies. I think I got enough to do 4 signs for about $30 including shipping. Got them from BangGood. Haven't hooked any up yet.
