I recently donated some work for a local community health center. I built some counters and a cabinet along with a sign that also serves as a partition (pics below). I only did the initial sketches of the sign. A real sign designer came up with the finished product, which I think turned out great.
Now they need an exterior sign, and I am suggesting using the same design. They want it in a lighted box, and they have a good metal-worker/welder who is going to build the box. I'm wondering about a few things. Is polycarbonate a good way to go for panels on either side of the box? And lighting, a strip of LED cord light? One idea from the guy building the box was to loosely pack spun glass in the box to help diffuse the light. I wonder if this is feasible, or if there's another practice to get an even light distribution. The sign will be 28" x 60".
I apologize for my naivety on this. Furniture and cabinets I can do, but I'm about as new to signs as possible. Thanks for any help you can offer.
