Battery compatibility: Powered by 1 × standard 21700 lithium battery (not included), the LHP73B, SFT-90 and F150R configurations require a high-drain battery capable of more than 20A. Always use a battery suitable for the selected LED configuration.

Operating Modes

The M21B supports 12 configurable mode groups. The operating mode group is configured through the flashlight's switch interface; it is not a separate LED or color-temperature variant.
