I have a customer looking for a backlit acrylic logo as part of a much larger job we are bidding on. We are just getting into more electrical signs and I've never done anything like this so I'm looking for some pointers or suggestions. The customer wants the main text and logo to glow blue and green. My plan is to get all the lettering cut out of 1/4" acrylic that will be stud mounted to the wall, probably about 1/2" off the wall. The LED modules will be stuck to the back of the acrylic. Where is a good place to purchase LEDs, specifically green and blue? Grimco shows green but not blue. How do I determine how many LEDs can be on a transformer? Any other suggestions or pointers from someone who has done this before? Attached is a sample layout with the name changed and logo modified but this gives a general idea what we are planning for. Customer has a full time electrician who will do the hook up.
