About 4 Watt Affordable Handheld Short Wave

This is an affordable, low wattage shortwave and longwave ultraviolet lamp used for the observation of mineral and rock specimens that fluoresce when exposed to shortwave or longwave 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. The shortwave light is a filtered 4 watt fluorescent tube that emits the shortwave UV at approximately 254nm. The longwave light is an LED located on the side that emits longwave UV at approximately 375nm. 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 shortwave ultraviolet 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. Requires 4 AA Batteries. Batteries are not included.
