With seven, ultra-bright, white LEDs, the Streamlight Septor LED Headlamp features three levels of lighting for a wide range of applications including up-close detail work and long-range viewing. Adjustable straps help secure the light to any head size, and a 90-degree tilt mechanism allows you to point the light exactly where you need it. Durable and water-resistant construction ensure extended use, and the Septor Headlamp runs on three "AAA" batteries (included). Weighing just 4.72 ounces, the Streamlight Septor LED Headlamp fits comfortably to your head with the included rubber hard hat strap, leaving your hands free to perform electrical work, set up a tent, look under the house, consult a manual, and more. You can use the Septor Headlamp anywhere you use a regular flashlight, but you'll have both hands available to perform the task at hand. This headlamp produces 50 lumens of light with seven LEDs, 25 lumens with three LEDs, or 9 lumens with one LED.
