Ownership verified by KD Nice driver but low pwm
Posted by Grayski74  on   5/21/2016 12:20:52 PM
Avg.Rating: star star star star

Strengths:

Good support for both eneloop and cr123a. Quite bright. Draws 2a on high from a cr123a, 550mah on medium, and 170 on low. Good mode choice. Fits most flashlights.

Weaknesses:

Bad pwm. One of the lowest frequencies I've ever seen on the lowest mode.

Summary:

A decent driver, with good mode choices, as long as you're not sensitive to pwm as it's very low frequency.
