I have never used a little light I see tons of people have at frag swaps to get an idea of coral coloration.
Is it just UV LEDs and the wavelength doesn't matter much? In a quick online search I saw a crazy set covering a spectrum of wavelengths (also crazy expensive). What are hobbyists using?
Any recommendations of cheap ones? Students would use them to examine frags when we study waves or other physics/chem and in an ocean class. If I were super cool I could find out if we could make our own from LEDs and Harbor Freight flashlights. Hmmm.
