*You will need a true filtered Shortwave UV light in order to see the fluorescence shown in the pictures. A Longwave UV light will show some fluorescence but not the best.
Shortwave lamps have a range of 200-280 nm.
Longwave lights have a spectrum of 315-400 nm and are also called UVA.
Please feel free to contact us if you have any questions about fluorescence or fluorescent lights.
*Please keep in mind that exposure to UV light is dangerous. We recommend the use of protective goggles and gloves (or wearing sunscreen in the hands) when handling minerals under UV light*
