This flashlight draws a very high current from the batteries. You MUST use unprotected 18650s capable of 8A or more, and from name brand manufactures. Multiple pogo-pin battery contacts, rather than springs, are used in order to keep up with the high current draws and to consistently maintain an extremely low resistance over a long period of time. Unfortunately, only flat top unprotected 18650 batteries up to 65.2mm are compactible with the pogo-pin contacts. Frosted lenses have to be used in order to smooth out beam artifacts from quad die LEDs. The brightness can be perceived to be less compared to throwy lights with the same output.
Main Features and Specifications
LED: Cree XHP50 Cool White (Typical CRI: 70, Nominal CCT 5700K)
User Selectable Levels: 3 main levels (High, Medium and Low). Each main level can be programmed to one of its two sub-levels. The second sub-level of the each main levels can be further programmed to different brightness levels.
- Light Output
- High: H1 1800 Lm (PID, approx. 2.3 hr) or H2 800 Lm (PID, approx. 2.7 hrs) / 515 Lm (PID, approx. 2.9 hrs) / 324 Lm (4.1 hrs)
- Medium: M1 120 Lm (12.5 hrs) or M2 41 Lm (36 hrs) / 23 Lm (2.6 days) / 12.5 Lm (4.6 days)
Low: L1 3.5 Lm (15.5 days) or L2 0.91 Lm (1.9 months) / 0.44 Lm (2.7 months) / 0.22 Lm (4 months)
- Beacon Strobe Mode: 0.2Hz Beacon at Low / 0.2Hz Beacon at H1 / 4Hz Strobe at H1 / 19Hz Strobe at H1
Light output are ANSI out the front (OTF) values. Runtimes tested (and parasitic drain estimated) using Sanyo NCR18650GA batteries. Runtimes of the three PID controlled levels (1800, 800 and 515 Lumen) vary greatly with ambient temperature and air circulation.
Operating Voltage Range: 2.7V - 6.0V
Battery: One 18650 size (i.e. unprotected 65.0-65.2mm long) 3.6V-4.35V li-ion rechargeable. Batteries are not included in the package.
Parasitic Drain: Negligible (much less than the self discharging of a battery)
- Beam Type
- Head Diameter: 1.2 inch (30 mm)
Body Diameter: 0.98 inch (25 mm)
- Length: 3.8 inch (96 mm)

This light has 3 main levels (High, Medium, and Low) and a beacon-strobe mode. Each main level can be programmed to one of its two sub-levels. The second sub-level of each main levels can be further programmed to different brightness levels.
One short-click turns on the light to High or turns off the light.
Two short-click turns on the light to Medium.
Three short-click turns on the light to the beacon-strobe mode.
Press and hold (for over 0.6 seconds) turns on the light to Low and then Medium and High. Release at the desired level.
- Advanced Operation and Configuration
- Press and hold to cycle from Low, Medium and High, release at the desired level to set. When press and hold, the light always cycle from Low to High regardless which level you are currently in.
Double click to toggle and select between the two sub-levels for that main level. Sub-level selections for the 3 main levels are memorized after the light is turned off and through battery changes.
The second sub-level (H2, M2 and L2) of each main levels can be further programmed to different brightness levels. At a main level, double-click 6 times to start configuration. On subsequent double-clicks the light will cycle through different brightness levels. Short click to turn off the light when finishing configurations. The selections for the second sub-levels are memorized after the light is turned off and through battery changes.
This light uses the main LED (flashing 1 to 4 times) to indicate the estimated remaining capacity of the battery. To start the battery indicator, (from Off) short-click 4 times without pause.
Beacon-strobe mode can be accessed from 3 short-clicks when the light is Off. Once in the beacon-strobe mode, you can double-click to cycle through different types of beacons and strobes. Beacon-strobe settings are memorized when the light is turned off and through battery changes.
