Freeform stepless adjustment from 0 to 3000 lumens from the Luminus SFT-70 LED.

A USB-C charging port on the side of the SRT7i head is protected by a high strength metal cover and a 5000mAh 21700 (NL2150HPi) battery, plus charging cable is included. Full charge from flat takes only 2.5 hours.

Strobe: 3000 lumens

In addition to the smart ring adjustment, the SRT7i tail switch also features dual tail buttons with 2-stage mode button and separate power switch. Instant access to strobe is available from on and off positions. Randomly changing strobe mode changes frequencies that can cause stronger dizzying effects.

The strike bezel of the SRT7i is designed with high hardness silicon nitride ceramics, which enables a glass breaking while preventing scratches to clothes and backpacks.

Waterproof to IP68 (2 meter submersible for up to 30 minutes) and impact resistant to drops from up to 2 meters.

Advanced temperature regulation (ATR) regulates the output of the SRT7i according to the working and ambient temperature to maintain optimal performance while preventing the LED from overheating.
