This little uv penlight gives excellent "bang for the buck". It is small and as easily carried as a fountain pen. The descriptor here mistakenly says it uses 1 AAA battery, it actually uses 2 AAA's. It's output is practically all 365 nm, closer to true uv which is what you want. For buyers that have never had experience with uv lights, 365 nm light seems weak because the human eye doesn't "see" that wave length. The eye only sees objects that fluoresce when illuminated via ultraviolet light. Just shine this little jewel on a fluorescent subject and you'll understand what UV is about. Sure, one must understand that this light is a small output "penlight", and won't reach out there like some of the big boys such as the Convoy C8 (https://www.amazon.com/Convoy-365nm-Flashlight-Patented-Filter/dp/B08QCX1KTJ/ref=sr_1_5?crid=1VU6N5NHLL8KT&dchild=1&keywords=convoy+c8+uv+flashlight+365nm&qid=1633280857&sprefix=Convoy%2Caps%2C200&sr=8-5). The C3 is a monster that will throw a true UV beam for many feet.This light is designed for close inspection of objects within inches in very low ambient light, and it does that very well.It's construction is first rate and it uses a built-in filter that excludes frequencies other than true UV passing, so you see nothing other than that.For its intended use, this little light is the best unit I've seen here on Amazon, and I personally own several uv flashlights!
