This is NOT a blacklight. This light emits ultraviolet radiation with a wavelength of 254 nanometers. Only materials that react to this specific wavelength will respond to the UV lamp. Always use UV blocking eye-wear wile using this lamp with the shortwave bulb on.
Bulbs Included: 11 watt fluorescent tube 254nm Shortwave
Batteries Required: 3 D (not included) , Lamp size: 10 1/2" x 2 1/2" x 2"
LED: Built in LED flashlight on side of lamp
Includes a sample of multiple small fluorescent rock pieces and a stamp with every order (similar to 3rd picture) - Most common rocks/minerals included are calcite, fluorite, and willemite. Includes polycarbonate safety glasses that filter out 99.9% of harmful UV radiation.
LIMITED EDITION: This item is no longer being manufactured. Order while it is still available! This high output, short wave UV lamp is used for the observation of mineral specimens or other materials that fluoresce when exposed to short-wave ultra violet light. It is especially useful for taking out on the field with 11W short wave UV (high output) and a built in LED spotlight on the short side of the lamp. The lamp also includes an arm strap attached for easy carrying. 90% of fluorescent minerals require a filtered shortwave UV light. Because less than 10% of rocks will react to long wave UV light or black light, short wave UV lamps are ideal for the study of mineral fluorescence. The optical filter is a specialized piece of glass on top of the lamp. This is a UV (ultra-violet producing) lamp, NOT a long-wave "blacklight" and should be used only for practical purposes. Do not look directly into light. UV is harmful radiation. UV blocking safety glasses should always be worn while using the lamp.
