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 battery gauge clearly indicates how much battery you have left. Whether you wear with the adjustable silicone strap or attach it directly to a Klein® Hard Hat, this light-sensing auto-off headlamp is the best choice for your everyday light.
