Suited to both bare heads and hard hats, the LEDLENSER iH5 LED Headlamp is a lightweight, compact, simple light for professionals in industrial and mechanical settings. It's a versatile tool that can run on a single AA-size alkaline, NiMH, or li-ion battery. Change the beam between flood and spot with LEDLENSER's Advanced Focus System, and point the light where you need it with the 60° tilt capability. Select high power (200 lumens, 4.5 hours runtime) or low power (20 lumens, 35 hours runtime) with the push-button switch. The headband's rubber lining keeps the lamp securely in place on your head, cap, or hard hat, and the light can be detached from the headband and clipped on to clothing or used handheld. The iH5 carries an IP54 water-resistance rating and can withstand splashing water with no damage.
