Nitecore EF1 flashlight - 830 lumens

A flashlight with improved drop, shock and impact resistance, powered by a 18650 battery or 2 CR123A batteries. The EF1 model provides a light output of 830 lumens (measured behind the glass - ANSI FL1 Standard. Effective range up to 270 m. A flashlight that will survive even an explosion!

The body is made of aircraft-grade aluminum, thickened by about 20% compared to standard flashlights, and hard anodized in black. The design meets the IP67 standard (total resistance to dust ingress and resistance to immersion in water up to a depth of 1 m for up to 30 minutes). Resistance to falls from a height of up to 1.5 m. On the head, in front of the reflector, there is a steel crown, which allows the flashlight to be used as a weapon in a close combat situation. Thus built, the flashlight will perform in the toughest conditions.

An advanced electronic circuit controls current consumption, so that the flashlight shines in the selected mode with the same power almost until the battery is completely depleted. An Advance Temperature Regulation (ATR) system protects against diode overheating in the highest mode.
