Good light for a reasonable price.
"This is a mid-grade light for a moderate price. The included documentation does not cover every feature and S&W® does not seem to have a downloadable manual for it. The light is a good value once the following things about it are known: The light will only charge when turned on. It will blink the main light when charging and stop blinking when finished. It comes with a 16340 lithium cell with built-in protection. A regular 16340 cell should also work fine as long as the light is turned off when it dims to prevent over-discharging the cell after a few hours. The light is marked '16340 CELLS ONLY' The flashlight has four modes: Dazzle Strobe - 200 lumens for 4 hours*. Low - 30 lumens for 8 hours Medium - 100 lumens* for 4 hours*. High - 200 lumens for 2 hours. *Missing data has been estimated by measuring voltage and current values using an adjustable power supply and looking up the values on the Cree® XP-E2 R3 data sheet. On mine the rubber band that covers the USB charging port was hard to turn but a tiny dab of silicone grease spread around the band's track fixed that. It has been a good light but like most flashlights with a twist switch the internal contacts and O-ring seal should be kept clean."
