The rear switch allows for quick and easy momentary activation or constant-on activation, enabling rapid response and tactical maneuvering.

Performance

Flux	1600 lm
Intensity	8500 cd
Throw	184 m
CD/LM factor	5.31

With 1600 lm, the S1 flashlight will offer a brighter and more powerful beam of light. This higher output can be advantageous in various situations where you require enhanced visibility or need to illuminate larger areas. With 8500 cd, the S1 flashlight provides a noticeably brighter and more intense beam of light. It can illuminate objects or areas with greater clarity and visibility, even at longer distances.

The throw is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. The cd/lm factor (candela-to-lumen ratio) provides information about how concentrated or focused the light output of a light source is. A higher cd/lm ratio indicates that the light is more concentrated in a specific direction, while a lower ratio indicates a more diffused or spread-out light output.

Software

Firmware	BLF A6
Modes	4/7 modes
Mode memory	yes
Ramping mode	no
Strobe	yes
SOS/Beacon	no

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The S1 has mode memory. Mode memory means that the flashlight will remember the mode you were using when the light was last turned off, and when you turn it on again. The S1 is tactical strobe ready. The strobe light is disorienting to the person it is aimed at which makes it difficult for them to concentrate.
