Inexpensive compared to Fisher, VWR, etc. Works really well! Wonderful to be able to cut bands without having to wear goggles. Definitely recommend!
The model UVGL-58 Ultraviolet Lamp combines both short (254nm) and longwave (365nm) UV light in one handheld lamp with six watts of power for each separate UV tube. The lamp has dual switches for either long or short-wave use. The lamp's housing is durable, lightweight plastic that should last a long time. The lamp may be used for mineralogy identification, chromatography, document examination, and germicidal applications. However, this lamp is tethered to 120 volts AC from a standard wall receptacle and will not work with an automobile electrical inverter for fieldwork.
The lamp is also relatively expensive compared to other UV lamps in the same category. It would have been helpful if UVP had included directions with the lamp for removing the UV tubes and filter. An included booklet with online references that explains how the lamp may be used for specific mineral identification in the field would be helpful for the novice prospector.
Lithium is a strategic metal in high demand with limited distribution, and a field test using the UV lamp for identification would seem reasonable. Perhaps a modification of the UV spot test for the Lithium-ion below would be attainable
