- aluminium alloy with HAIII hard-anodized finish
The emitter of SF47T manufactured by Osram, a German lighting manufacturer. The SF47T has a smooth reflector. The properly focused smooth reflector gives you a more cohesive hotspot and therefore throws better. It has an AR coated lens.

- Color temperature
- 6500 K
- toughtened AR coated glass
- electronic side, mechanical rear
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.
- 1500 lm
- 303750 cd
- 1102 m
- CD/LM factor
The SF47T 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 SF47T is intuitive, and lets you seamlessly ramp the output up and down over almost the entire output range. The SF47T is tactical strobe ready. The strobe light is disorienting to the person it is aimed at which makes it difficult for them to concentrate. It has the SOS beacon function for an emergency situation. The SOS flashes Morse code so you can signal for help when needed.
- 5 modes
- Mode memory
- Ramping mode
The battery indicator lets you know when the battery is low, charging, or fully charged. The SF47T 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. The built-in thermal control automatically adjusts brightness output to prevent overheating.
- 2 x 21700 Li-Ion batteries
- Battery indicator
- Charger port
- Thermal regulation
- Impact resistance
- 1 m
- AUX LEDs
The performance of the Sofirn SF47T 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 Sofirn SF47T, then don’t hesite and signal the problem to us.
