NEBO Einstein Features The Nebo Einstein headlamp delivers up to 100 lumens of output bright enough for close-range tasks like setting up camp field dressing game or navigating dark trails. Its internal rechargeable 3.7V lithium-ion battery means users never need to stock up on disposable batteries making it a cost-effective choice for frequent outdoor use. Recharging is simple and keeps the headlamp ready to go for the next hunting trip camping excursion or late-night chore. The compact 1.75-inch width keeps the unit low profile and comfortable against the head during extended wear. At a mere 0.25 lbs the Einstein adds negligible weight to a hat or headband making it easy to forget it is even being worn. Its hands-free design frees up both hands for tasks like loading a firearm setting up a tree stand or preparing a meal at camp. The black finish keeps the headlamp low visibility for nighttime hunting or tactical applications where minimizing light signature from the housing matters. For anyone who needs dependable rechargeable hands-free lighting the Nebo Einstein headlamp is available for sale at GrabAGun.
