The Femto Duo is a two-in-one safety light integrated into a versatile helmet mount. Evolved from our popular Femto series, the unit features a front and rear light coupled by a composite matrix junction that’s compatible with nearly all vented-style helmets. The LEDs are housed in a super-compact, lightweight and durable machined aluminium body, and the high-grade polycarbonate lenses provide side visibility and double as the power button.
The front emits 15 lumens, while the rear puts out 7 lumens; both feature three different output modes. With easy to replace CR2032 batteries, the Femto Duo is a simple front and rear lighting system for increased nighttime visibility.
