I use UV-led strips. The LED strip I used has 60 Leds a meter with a 395-400 nm wavelength. I also made a video about this Setup: ua-cam.com/video/bUmAwSqyVqA/v-deo.html.
I either use transparencies for overhead projectors or screenprinting. Over the years I've tried a lot of different ones and all worked, so don't worry too much. I use a standard office ink jet printer to print on them. Hope that helps!
