UV Light Box @ Magic Smoke. Dieter writes -
It contains two sections of 54 LED’s each, one for the top and the other for the bottom. It runs off 12V DC and draws about 1.2A. I found that an exposure time of three minutes gives good results. Keep in mind that UV light is extremely bad for your eyes and you should always take the necessary precautions operating equipment like this. In order to avoid unnecessary exposure to harmful UV rays, I added a micro switch in the lid that will switch the light source off when the lid is lifted.
