This flashlight has waterproof O-Ring, adopts high-power LG 365nm UV LED with a ZWB2 UV bandpass filter installed, ensuring block the majority of visible light emitted by the LED. This will ensure experience accurate mineral fluorescence colors.

* It activates fluorescence in minerals not thought to be LW fluorescent especially due to the UV filter I have installed. You will get accurate, intense fluorescence from well known longwave fluorescent minerals like Fluorite, Sodalite, Hackmanite.

* You will also see a fluorescent response with many minerals which normally only glow under shortwave UV illumination. Many calcites unexpectedly fluoresce and exhibit phosphorescence under this light. Franklin, NJ Willemite, Calcite and Sphalerite all fluoresce under the 365nm filtered UV of the Conway S2+ Longwave Mineral Light.

* Apart from detecting some minerals, it can also detect counterfeit Banknotes, fluoresce in cosmetics and baby stuff, Discover invisible inks, diamonds, amber, jade, jewelry, documents verifications, amber, jades, pearl, stamps, invoice etc.
