The throw is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. The candela per lumen (cd/lm) ratio can be used to determine if a flashlight has a spot or flood type beam. Well-focused spot beams can be over 100 cd/lm, tactical flashlights are typically between 20-100 cd/lm, and work lights are less than 10 cd/lm.

The H40 SST20 has mode memory. Mode memory means that the light will remember the mode you were using when the light was last turned off, and when you turn it on again. The ramping mode of the H40 SST20 is intuitive, and lets you seamlessly ramp the output up and down over almost the entire output range. It has the SOS beacon function for an emergency situation. The SOS flashes Morse code so you can signal for help when needed.
- 3 modes
- Mode memory
- Ramping mode
The H40 SST20 cannot charge batteries directly. You may need an external charger to keep your battery going. This flashlight has a built-in low voltage protection (LVP) to prevent damage to the cell from over-discharge, so protected cells are not necessary. This light does not have temperature control feature.
- 1 x 14500 Li-Ion or 1 x AA NiMH battery

- Charger port
- Thermal regulation
- AUX LEDs

- 2 x spare o-rings
The performance of the Acebeam H40 SST20 flashlight is measured according to the ANSI / NEMA FL1 Standard 30 seconds after switching the light on. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
The specifications above are based on the official data published by the manufacturer, but we also take user reviews into consideration. If you found an error or something lacking in the specifications above for the Acebeam H40 SST20, then don’t hesite and signal the problem to us.
