I don't usually write reviews because I've seldom found a product that deserves the additional time from my day. The realUV™ LED Flashlight with BLACKOUT™ Filter Technology was the exception. My 50 year work life centered around nuclear energy, propulsion and electric power generation, where quality and performances were never compromised. Over the years I've used UV lights in many applications and configurations; none of the portable, battery operated lights that passed through my hands come close to the performance of this light. Is it pricey? Yep, but worth every penny and more if you want results. If you want performance and quality you have to pay for it. You get it with this light from Waveform Lighting.
This little light is pretty amazing. The fluorescence of certain objects or elements is on a whole other level with this light. Rocks that barely had any glow to them at all using a regular UV light are crazy bright with colors using this light. This is a very serious light and you need UV blocking eye protection. Shining the light at objects without eye protection will hurt your eyes. Best just to keep the eye protection with the light.
Works well - very bright, the black glass filter is nice to reduce the visible portion of the beam.
