365nm UV Flashlight Visible Filter Lens 1pcs

I got this filter specifically for my Convoy S2+ Nichia flashlight, which emits both UV and visible light. I wanted to turn it into a black light by blocking the visible light. I got this filter for that purpose. Well, the filter also blocks UV. If you make my mistake, you will basically just have a very dim red flashlight.To the seller's credit, he did issue me a full refund.

There was an issue with the tracking number that I was first sent so I contacted the seller. I received a response very quickly and the tracking number issue was fixed. Once I received the filter I installed it on the Convoy S2+ 365nm (from Gearbest) and I was amazed! I like it so much I bought a second Convoy and another filter to go with it. Highly recommend this if you are interested in 365nm pure light.

Bought to make flash light an ultraviolet light but no light passes thru!

These are not UV, they are IR!!! Apparently the seller does not know the difference!!

Great filter, almost all visible light removed.
