The Lightbar headband is comfortable and feels more like wearing a baseball cap than a bulky headlamp. Enjoy all-day comfort with a lightweight design. The Lightbar headband has a 210° range that shines brighter than most traditional headlamps. It does this by utilizing an array of 2835 LED lights that are powerful enough for any job but not enough to prevent you from carrying out your work. It comes with 4 brightness levels, is durable, can easily be cleaned, and has 5 hours of light (requires 3 AAA batteries and is not the rechargeable unit). You can also purchase an additional Lightbar rechargeable battery (USB) to get more battery life. The Lightbar Headband comes in 3 models (Lightbar, Lightbar Sport, Lightbar Pro) and is perfect for working on projects, hiking, climbing, fishing, etc.
