Klein Tools' rechargeable headlamp provides three modes to fit your task: a bright, 22-hour floodlight; a brighter 12-hour focused spotlight, and a super-bright 400 lumen boost mode. You'll know when it's time to recharge the lamp, because the LED lights on the battery gauge clearly indicate how much battery you have left. The adjustable fabric strap is comfortable and has just enough silicone weave to keep it in place. Whether you wear with the strap or attach it directly to a Klein® Hard Hat, this light-sensing auto-off headlamp is the best choice for your everyday light.
