Product Highlights

Lightweight, powerful and affordable, the Black Diamond Cosmo headlamp delivers performance lighting for backpacking and camping. Multiple brightness settings and a strobe feature make the Cosmo a versatile backcountry companion.

A durable, rubberized toggle switch on the top of the Cosmo's housing makes the headlamp easy to operate. At its brightest setting, the Cosmo's DoublePower LED bulb produces a beam that reaches over 130 feet. Additional settings allow you to regulate the length of the beam for increased burn time and proximity lighting. By using the Cosmo's lowest, most economical setting, you can expect a burn time of up to 250 hours. A strobe setting produces a pulsing light for emergency signaling.

The Cosmo requires three Alkaline AAA batteries (included). Even with the batteries, the Cosmo weighs just 3.2 ounces.

An elastic headband adjusts to enhance comfort and ensure that the Cosmo remains securely in place while in use. The housing of the Cosmo is hinged so you can angle the beam as needed for the conditions and the task at hand.

Water-resistant and suitable for all-weather use, the Black Diamond Cosmo headlamp is available in your choice of colors.

Colors available: Bright Teal, Dark Shadow, Matte Black, Plum, Process Blue, Ultra White, Vibrant Orange
