LED and Color Temperature Options

Select your preferred LED emitter, available color temperature, and body color from the product options. Available color temperatures vary by LED. The selected LED and driver configuration determine the flashlight's output characteristics and operating behavior.

Battery Compatibility

Battery is not included. The Convoy M21B uses one standard 21700 lithium-ion battery and is compatible with flat-top 21700 cells. Check the battery dimensions and discharge capability before ordering.

The LHP73B, SFT-90, and F150R high-output configurations require a high-drain 21700 battery capable of delivering more than 20A of continuous discharge current. Suitable batteries include:

• EVE 40PL
• EVE 50PL
• Molicel P45B
• Molicel P50B
• Samsung 50S
• Ampace JP40

Do not use a standard high-capacity cell that does not meet the required continuous discharge current for these high-output configurations.
