If you have to have the lightest headlamp, the Black Diamond Ion is it. Weighing in at a feathery 1 ounce with battery.
The new redesigned Black Diamond Ion is a great ultralight headlamp. It is small enough to stash just about anywhere, plus the reflector-housed, 1/2 watt LED casts a far-reaching beam for finding your way.
The Ion has a pivoting head that angles the light anywhere you need it, and a replaceable 6-volt battery provides power for 15 hours at the low setting and 3 hours on high. The Ion is unnoticeable in size and weight, but don’t let its diminutive size fool you—this two-setting headlamp is tough and durable, able to withstand apocalyptic levels rain and sleet.
Slim half-inch elastic headband adjusts with a slider to fit over a different size heads, hats or climbing helmets. A switch on the underside of the light toggles between On and Off.Burn Times
