EC
The Klarus EC20 is a round-body LED handheld light rated at 1,100 lumens and 10,000 candela. That candela figure works out to an effective positive identification distance of 34 yards and visual impairment out to 4 yards, both calculated from the published beam data. It runs on Lithium Ion and is rechargeable. It weighs 5.29 oz in an aluminum body 4.92 inches long. Measured against the 362 handheld lights in the index, it lands on the dimmer side for output (1,100 lumens), in the least intense quarter for beam intensity (10,000 candela), about in the middle for weight (5.29 oz), and among the least expensive 10 percent for price ($40). 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 Klarus A1 PRO, the same brand's light in the same 1,000 to 1,999 lumen class, priced at $35.
