*A Longwave lamp will show the sphalerite fluorescence, but the calcite will be less vibrant. A shortwave lamp will show the calcite fluorescence better.
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*
