I put an array of UV LEDS on a ceramic block and connected to a power source, as a means of detecting very small crystals once they are in the loop. The most difficult part was supporting the LED block so that it shone onto the loop but did not obstruct the user. The so-called UV LEDS are often black light not UV. A small, real UV torch or keyring light may actually be better.
