Weighing just 3.3 ounces, you'll barely know you're wearing the LEDLENSER H14R.2 Rechargeable Headlamp. But if you're jogging, cycling, or walking the dog after dark, drivers will know—because they'll see the headlamp's rear-facing red LED light, an important safety feature. The lamp delivers a maximum of 250 lumens with low, high, and boost settings, and tilts to put the light right where you need it. Runtime ranges from 3 to 40 hours, depending on the brightness level selected. A multi-function switch on top of the lamp controls power and brightness settings. Its IP57 water-resistance rating means you'll have nothing to worry about if the headlamp briefly ends up under water.
