The built-in 1800mAh li-ion battery pack provides up to 8 hours on the high setting or up to 147 hours on moonlight. When depleted, the battery can be recharged in only 3 hours.
Ergonomic Controls of Three Light Sources
Harness the power of illumination with three different light sources. The primary white light gives you up to over 400 feet of throw, which is great for getting situation awareness or when using SOS/Beacon modes in emergencies. The auxiliary white light is great for close-up tasks and has a high CRI rating, so you can see objects in their most vibrant colors. Red light mode makes it easy to preserve night vision. All these options are accessible through two buttons located on the top of the lame – they are different shapes, making it easy to identify and utilize each.
Safeguarded and Ready to Travel
Take your light out backpacking or to different jobs with peace of mind! Lockout mode will protect you from accidental activation when transporting your NU31 in a pocket or backpack. The IP66 rating gives you ingress protection from dust and water. With a durable front aluminum housing, you can trust your NU31 can stand up to wear and tear while you’re on the move!
