Nitecore GEM10UV
The Nitecore GEM10UV is a round-body LED handheld light rated at 300 lumens and 3,000 candela, with UV output. That candela figure works out to an effective positive identification distance of 18 yards and visual impairment out to 2 yards, both calculated from the published beam data. It runs on AAA and is not rechargeable. It weighs 1.1 oz in an aluminum body 5.3 inches long. Measured against the 362 handheld lights in the index, it lands among the dimmest 10 percent for output (300 lumens), among the least intense 10 percent for beam intensity (3,000 candela), among the lightest 10 percent for weight (1.1 oz), and in the least expensive quarter for price ($70). It is one of 24 entries in the index that qualify as a light in the same under 500 lumen class. The closest listed comparison is Armytek Dobermann XP-E2 Red, another light in the same under 500 lumen class, priced at $70.
