Whether you're hunting at shows, checking specimens at home, or adding a finishing touch to a display, this keyring torch is an indispensable addition to your collection kit.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUV torches at 365nm emit longwave ultraviolet light — the optimal wavelength for exciting fluorescence in a wide range of minerals including calcite, fluorite, scheelite, willemite, and many others. Unlike shorter-wave UV (254nm), 365nm light is eye-safer and more effective at revealing vivid colours in fluorescent specimens without washing out the effect.\u003c\/p\u003e\n\u003cp\u003eFluorescence is nature's reminder that there is always more beneath the surface. Many collectors find UV work a meditative and revelatory practice, deepening their connection with each specimen.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLight wavelength:\u003c\/strong\u003e 365nm ultraviolet (UV-A)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLight source:\u003c\/strong\u003e LED\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e Keyring torch \/ portable handheld\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions: \u003c\/strong\u003e23 x 40mm excluding keyring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eUV light is not eye safe - never stare into the beam and be aware of reflections.
