The new NightRay uses five Superbright LEDs to light up the night. Its center LED is lensed, allowing it to project a beam of light, while the other four LEDs offer brilliant proximity lighting. You can toggle between a two LED or a five LED option and the output can be adjusted using three brightness settings including strobe illumination. The NightRay's streamlined battery box holds 3 AAA batteries and is easy-to-access. Weighing only 90 grams, the NightRay is our lightest and most compact, full-function headlamp.
