This is a lamp that I made for a friend. I used 1/2″ acrylic sheeting. The adhesive backing was the biggest pain to get off since the acrylic had been sitting in a garage for several years. First I routed out the letters about 1/8″ deep. Then I took an old chisel ( AND SAFETY GLASSES) and chipped away at the edges and inside the letters. Once the LOGOS was done, I drilled three holes in the base and glued in 10mm blue LEDs.
