The Klarus E2 is a round-body LED handheld light rated at 1,600 lumens and 5,625 candela. That candela figure works out to an effective positive identification distance of 25 yards and visual impairment out to 3 yards, both calculated from the published beam data. It runs on 18650 and is rechargeable. It weighs 1.94 oz in an aluminum body 4.69 inches long. 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 (5,625 candela), among the lightest 10 percent for weight (1.94 oz), and in the least expensive quarter for price ($70). It is one of 127 entries in the index that qualify as a light in the same 1,000 to 1,999 lumen class.
