A durable headlight with Auto-Focus Technology to deliver optimal lighting in any situation so you can get the job done. The distance-seeking infrared sensors automatically adjust between Spot Mode for lighting precise areas at a distance, and Flood Mode for lighting large areas at short distances. You get hands-free performance in multiple ways: use it as a headlight with the cloth strap, on hardhats and helmets with the silicon headstrap, or mount the light on metal surfaces using the magnetic base. The polycarbonate body and IPX4 water-resistance provide durability to handle any job, and the storage lock prevents battery drainage from accidental power button presses. It runs on 3 AAA batteries (included), with up to 37 hours of runtime using Energy Saver Mode.
