The ThruNite Defender is a flat-body LED handheld light rated at 1,600 lumens and 4,880 candela, with White and UV output. That candela figure works out to an effective positive identification distance of 24 yards and visual impairment out to 3 yards, both calculated from the published beam data. It uses an integrated battery pack. It weighs 3.81 oz in an aluminum body 4.65 inches long. An integrated green laser is fitted. Measured against the 362 handheld lights in the index, it lands about in the middle for output (1,600 lumens), among the least intense 10 percent for beam intensity (4,880 candela), on the lighter side for weight (3.81 oz), and in the least expensive quarter for price ($60). It is one of 127 entries in the index that qualify as a light in the same 1,000 to 1,999 lumen class. The closest listed comparison is ThruNite Coreforge, the same brand's light in the same 1,000 to 1,999 lumen class, priced at $60.
