Convoy L21B SFT40, 2000 Lumens, 1200m Range

Convoy L21B SFT40, 2000 Lumens, 1200m Range

ANSI FL1 Standard: 2,000 Lumens

Range: Turbo: 1,200m, High: 850m, Med: 480m, Low: 150m, Ultra-Low: 60m



The L21B has been recently updated so it no longer requires my own modified battery. The positive terminal now has a regular spring to take any 21700 battery. If this is going to be gun mounted it must use a 21700 with added button top, this prevents damage to the battery's top from recoil.


12 Selectable Mode Groups: See my video tutorial in the gallery.

Note: On 100% after 3.5 min, a gradual stepdown occurs over 9 min. This is on a timer, not a temp limit, so it can be reactivated as needed. Reactivation will get hot so be careful.
