The Optik High-Power Headlamp from NAPA features the latest Cree LED technology. This compact headlamp has a 120-lumen output to illuminate the entire work surface. The long-range beam is effective up to 100m. To help reduce neck fatigue, the compact head design tilts 90 degrees and ratchets into the desired position. Powered by 3 AAA alkaline batteries (included) the Optik High Power Headlamp will provide a 3.5-hour run-time.
