Built for cold weather, Princeton Tec's Apex Extreme Headlamp powers through the dark. Batteries are stored in a remote compartment that can be kept close to your body for optimal battery life when the temperature drops. This also reduces the weight on your head. Four ultrabright LEDs and one Maxbright LED cut through the darkness with either a powerful spot beam or a bright flood. 275 Max lumens. Includes battery meter. Uses eight AA batteries (included). Runs up to 200 hours on low. Wt: 14.7 oz.
