Black Diamond Ion

Compact headlamp

Brand: Black Diamond Gear Reviews

Model: Ion




Our take At just 1.9 ounces including two AAA batteries, the redesigned Ion is the perfect just-in-case light. But unlike most just-in-case lights, this compact headlamp is more than an insurance policy: It boasts a respectable 100 lumens and also includes Black Diamond’s low-power red light for close-quarters use. Testers kept it in their packs for after-work cragging sessions that had us hiking down scree fields and steep trails in the dark. It has serious staying power, lasting up to 180 hours on low, and includes a lock mode to stop it from accidentally turning on in your pack. Bonus: An IPX8 waterproofing rating means it can be submerged a meter underwater, light on, for up to half an hour.

Trail cred “It’s so light, there’s no reason not to carry it,” says one editor who took it on trail runs and trad climbs in Boulder’s Flatirons. “I liked the simple, one-piece size adjustment on the back of the strap, too.”
