HQRP - 365 nm UV Blacklight - 3 W USB Rechargeable Pocket Torch with Optical Filter + Sodalite Rough Stone 884667

Wavelength 365 nm and 3 W output make this UV blacklight flashlight well-suited for checking minerals and crystals for integrity, including cracks and inclusions, and for viewing fluorescence in stones that respond best to a true 365 nm source. The built-in optical UV filter helps block unwanted visible light and improves UV purity, giving clearer fluorescence contrast on rocks, gemstones, and crystal specimens. The pocket-size aluminum body includes a simple on/off switch and measures about 5 in long x 1 in diameter for easy carry in a pocket, tool bag, or mineral kit. USB rechargeable operation includes a built-in high-capacity battery and a USB charging cable, compatible with computer USB ports, power banks, USB wall adapters, and car USB chargers. Also included is 1 pc rough sodalite stone so you can immediately see a glowing mineral effect; for maximum fluorescence, illuminate the mineral in complete darkness. Protected under US patent 7,781,751. Use UV safety glasses and avoid shining the light into eyes.
