since I'm a bit of a fiend for flashlights and the last post went well I thought id share again.
specs for nerds: (from listing)
1.Emitter:single SST40 powerful LED
2.Working voltage: 2.8V-4.2V
3.Battery Supported: one 18650 li-ion battery
4.Dimension: 117.5 mm (length) x 25.4mm (head diameter)
5.Net Weight: 59g without battery
6.Made by Aircraft 6061 grade-aluminum alloy, Premium type Ⅲ hard-anodized anti-abrasive finish to get solid built body, anti-crash.
7.Toughened mineral glass lens
8.Mode Memory: It memorizes the last brightness level used in the general modes. It will activate the last brightness you selected, when you turn on the flashlight next time.
9.Advanced temperature regulation (ATR) technology：It adjusts the brightness level automatically when the light temperature reaches 45℃ to keep the light from overheat. You can reset the temperature limit, please contact us if you want to know more details.
10.Low Voltage Protection:LVP makes the light step down to a lower level when the battery is lower than 2.8V, and if the light is already at the lowest level, it shuts itself off.
• Turn ON/OFF
Single click the side switch to turn the light on/off.
• Change Brightness
Press and hold to ramp up or down
• TURBO is only for short times. At around a minute you may notice it dims slowly down! The user should use it only for short periods instead of relying on thermal regulation to prevent heat damage. Full turbo is powerful enough to start fires in just a few seconds, especially when aimed at dark-colored materials.
