Olight vs Streamlight

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.

630 m works back to about 99,200 candela. That is a genuine thrower: nearly three times the ProTac HL-X's intensity from twice the lumens, which means a much tighter hotspot.

The trade is spill. At that concentration you get a bright circle and very little else, which is superb across a field and awkward in a corridor.

No published runtime is a real gap on a light this bright. Sustained output is the question a 2,600-lumen thrower most needs to answer.

Skip this ifyou work indoors. The beam is built for distance and it is the wrong tool inside a building.

2,000 candela and 90 m are consistent with each other, which is a better sign than it sounds. The FL1 beam distance is the square root of candela divided by 0.25 lux: the square root of 2,000 over 0.25 is 89.4 m. Streamlight's published figures check out to within a meter.

Two hours on high for 500 lumens implies roughly 2.5 watt-hours of usable energy, which is about right for a light this size. Nothing here is being oversold.

62 grams is pocketable in a way that a 21700 light is not, and that is the trade you are making against a bigger cell.

Skip this ifyou want reach. 2,000 candela is a close-range beam and no setting will change that.

1,600 lumens in a body this small is a thermal problem, not an optical one. Every light in this class steps down within a minute or two, and the honest way to read the number is as a burst.

Olight's magnetic charging is the best-executed version of the idea: no port to flood, no cable to thread, and the light sits on a dock.

We could only reach the brand's retail listing, so output and charging are the only figures we assert.

Skip this ifyou want to know how long it holds high. Without a published step-down table, the headline is unverifiable.

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.
