Xenopus Electronix will custom make your ultraviolet, wavelength-selectable, or even blood-detectable flashlight for you. Now even if you are not in a line of work which requires this type of flashlight, we have found that having one is useful to have around the house. If you live in the hill country for instance, you can use the ultraviolet light to find scorpions. They have night vision capabilities as well. Check out the website for more information, because as a lay person I have limited details. But on this website it details the types of lights and uses for them. Any questions you have are answered very quickly and the staff is very knowledgeable. Custom orders are taken, too and they will design any type of light you need. It's awesome.
