Streamlight ProTac 2L-X
The Streamlight ProTac 2L-X is a round-body LED handheld light rated at 500 lumens and 6,800 candela. That candela figure works out to an effective positive identification distance of 28 yards and visual impairment out to 4 yards, both calculated from the published beam data. It runs on SL-B26 and is rechargeable. It weighs 4.4 oz in an aluminum body 5.14 inches long. Measured against the 362 handheld lights in the index, it lands among the dimmest 10 percent for output (500 lumens), in the least intense quarter for beam intensity (6,800 candela), on the lighter side for weight (4.4 oz), and in the least expensive quarter for price ($65). It is one of 61 entries in the index that qualify as a light in the same 500 to 999 lumen class. The closest listed comparison is Streamlight MacroStream USB, the same brand's light in the same 500 to 999 lumen class, priced at $65.
