Best flashlights for police and law enforcement

Two hours at 2,000 lumens is the standout number: that is a whole traffic stop at full output rather than the ninety-second burst most 2,000-lumen lights give you.

350 grams is heavy in the hand and irrelevant on a belt. This light is designed around a duty rig and a vehicle charger, and the mass buys the runtime.

315 m from 2,000 lumens implies about 24,800 candela — a broader beam than the ProTac's, which is the right call for searching a room rather than a treeline.

Skip this ifyou do not have somewhere to dock it. A cradle light without a cradle is a heavy flashlight with a proprietary cell.

35,000 candela and 374 m reconcile exactly: the square root of 35,000 divided by 0.25 is 374.2 m. Streamlight's numbers are internally consistent across all three modes, which is the strongest signal of a maker publishing real measurements rather than marketing figures.

1.5 hours at 1,300 lumens implies roughly 6 to 7 watt-hours of usable energy — consistent with a single 18650-class pack and with the CR123A alternative.

IP68 with 2 m impact resistance is the toughest rating in this roundup, and the reason this light shows up on so many duty belts.

Skip this ifyou want a pocket light. It is a duty-belt tool and the weight and length are built for a holster.

8,700 candela works out to a 186 m FL1 beam distance, which SureFire does not print. That is well short of the ProTac's 374 m on similar output, because SureFire deliberately builds a wider beam with more usable spill.

Two modes, low then high, with no strobe and no programming. On a light you might need in a hurry, that is a feature.

CR123A primaries hold their charge for a decade on a shelf. For a light that lives in a drawer against the worst night of your life, that matters more than rechargeability.

Skip this ifyou buy on specification. Almost everything here beats it on paper; you are paying for reliability and simplicity instead.

2.75 hours at 600 lumens from two CR123A cells is a very efficient result — that is roughly 6 watt-hours doing real work rather than being thrown away as heat.

3 m of impact resistance is the highest figure in this roundup. Polymer absorbs a drop that would dent an aluminum body.

119 g with cells installed makes this the lightest full-size duty light here.

Skip this ifyou use a light daily. CR123A primaries are the wrong economics for frequent use; buy a rechargeable instead.

A 5,000 mAh 21700 at 3.6 V is 18.0 watt-hours — nearly three times what the ProTac HL-X carries. That is the case for the 21700 format in one number.

380 m of reach on 2,800 lumens works back to about 36,100 candela, almost identical to the ProTac's 35,000 from 1,300 lumens. The Fenix is spending its extra output on spill, not on distance.

169 g including the cell is only 7 g more than a ProTac on CR123A, for nearly triple the energy. That is what four years of cell development buys.

Skip this ifyou need a shelf-stable light. A rechargeable cell self-discharges; for a drawer light, CR123A primaries are the right answer.
