This is an affordable, low wattage shortwave ultraviolet lamp used for the observation of mineral and rock specimens that fluoresce when exposed to shortwave UV light. The lamp is best suited for beginners or for conveniently carrying on the go. Note: If you are needing a light for field work or for a display, you will need a much stronger lamp.

This lamp includes a 4W Shortwave fluorescent bulb behind a special optical filter (the long side), and a LED Spotlight on the short side of the lamp. The high quality filters on this lamp block all visible light that may interfere with a mineral’s fluorescence. The LED spotlight is perfect for use in the field when looking for mineral specimens so there is no need to carry an additional flashlight. An arm strap is attached to the lamp to prevent accidental drops. 90% of fluorescent minerals require a filtered shortwave UV light. The optical filter is a specialized piece of glass covering the fluorescent tube that blocks most visible light, but lets specific wavelengths of ultraviolet pass through. Please remember that UV light is not visible to the human eye! The reason for the filters is to block out as much visible light as possible, so only UV wavelengths pass through!

Because UV light can be very harmful, UV blocking safety glasses should always be worn to protect eyes from damage. We include one pair of safety glasses made of polycarbonate with purchase of the lamp. The glasses filter 99.9% of harmful UV radiation. Avoid UV exposure to the eyes and skin.

A sample of multiple small fluorescent mineral rock pieces and a stamp (as shown in the 2nd picture) is included with every order. Also try it out with the Fluorescent Rocks Mineral Collection!
