The Nitecore GEM10UV is a powerful ultraviolet LED flashlight designed specifically for gemstone identification and inspection. Jewelers, appraisers, and gemologists will find it an indispensable tool, particularly effective for amber and diamond detection. Its compact size also makes it a perfect everyday carry (EDC) light for law enforcement and security professionals involved in currency verification or forensic work. Featuring a UV output of 3000mW at a wavelength of 365nm, the GEM10UV offers bright, precise illumination essential for professional-grade analysis.
One of the standout features of the GEM10UV is its innovative rotary switch that provides infinite brightness control. This unique dial allows users to smoothly adjust the output to the exact intensity required, simply by twisting the switch clockwise or counterclockwise. The rotary control is easy to operate, even when wearing gloves, making it a user-friendly option for professionals working in various conditions. This feature ensures that the light can be tailored perfectly for any task, from subtle gemstone inspection to more intense ultraviolet illumination.
Despite its advanced capabilities, the GEM10UV is remarkably lightweight and compact, weighing just 2.34 ounces without batteries and measuring 5.31 inches long by 0.62 inches in diameter. Its slim, ergonomic design fits comfortably in the hand, reducing fatigue during extended use and preventing the bulkiness often associated with specialized flashlights. Additionally, the body is marked with a printed ruler, providing a convenient measurement scale to aid quick and precise gemstone size calculations, adding another layer of functionality to the tool.
Powered by either a single rechargeable 18650 battery or two CR123A batteries, the GEM10UV boasts an impressive maximum runtime of up to 500 hours on its lowest setting, ensuring reliability during long sessions of detailed work. On turbo mode, it can provide intense UV light for approximately one hour. The flashlight also features a highly efficient constant current circuit and an Advanced Temperature Regulation (ATR) module, which maintain stable output while protecting the device from overheating during extended use.
Built for professional environments, the GEM10UV is constructed from aerospace-grade aluminum alloy and finished with a military-grade hard-anodized coating for durability. Its toughened ultra-clear mineral glass lens has an anti-reflective coating to enhance light transmission and minimize loss. The flashlight is rated IPX8 waterproof, capable of submersion up to two meters, and impact resistant to drops from one meter, making it resilient for use in challenging conditions. Additional features include tail stand capability for hands-free operation, making the GEM10UV versatile and dependable for any professional’s toolkit.
