Acebeam T37

Acebeam's 2025 duty light pairs a Luminus SFT-90X with a rotary magnetic ring, so brightness is set by turning the collar and the two-stage tail switch only handles on, off and momentary. Turbo is 4,000 lumens at 48,400 candela for a 440-metre beam, stepping to 700 lumens after a minute and running three and a half hours from the 5,000 mAh 21700. A hidden USB-C port refills the cell in two and a half hours and the body is IP68. The emitter is 6500K with no CRI figure, and the maker's 202-gram weight does not say whether the cell is included.

Beam profile

Balanced, about 19° wide. A usable hotspot with enough spill to see around it.

Estimated from 4,000 lm ÷ 48,400 cd — how this works
