9 Watt UV LED Light
XNieFlashF-9W: 9 Watt 365nm UV Light with no filter
XNiteFlashF-9W-CH: 9 Watt 365nm UV Light Cultural Heritage Edition with UV Shortpass Filter and Tripod Mount
These UV lights are quite powerful. The lights have 9 x 1 Watt 365nm LED's with each LED having its own focusing reflector. This keeps the beam tight even over very long distances. The Cultural Heritage Edition light includes a removable tripod mounting bracket and UV shortpass filter in the front which substantially eliminates any visible light resulting in a purer UV beam with almost no reduction of power at 365nm.
In a test to see how far the light can through a UV beam, we taped some of our UVXPBR fluorescent red dye to the side of a shed and using the 9 Watt UV light.
