Our ratings (out of 10)
1 to 10, compared with the whole market. Each says what it's based on. How we score
Brightness
From maker's figures 8/10How much light it gives at full power, for finding your way in the dark. 8: Clearly better than most.
Maker's figure, 750 lumens with no test standard stated on Black Diamond's product pages: the 500–799 band, the most a maker's figure can score (maker's figure). Its instruction sheet gives 4.5 hours at this level.
Runtime
From maker's figures 10/10How long one charge or set of batteries lasts at a level you can walk and cook by. 10: The best you can buy for this.
Black Diamond's instruction sheet (linked from its product page) gives 20 hours on Medium (200 lumens), the longest it gives for a mode of 80 lumens or more: the 10 h+ band. High (750 lumens) lasts 4.5 hours. The product pages show only 80 hours, which is the 35-lumen Low mode. Needle Sports prints the same table.
Weight
From maker's figures 4/10How much it adds to your pack and your head. 4: A bit below average.
Black Diamond lists 114 g (US and EU pages and the instruction sheet agree) for a lamp with a built-in battery, in the 110–149 g band. GO Outdoors, Needle Sports and Alpinetrek give the same 114 g.
What reviewers say (out of 10)
Ratings marked * are from reviews and are not part of the trip score. They are reviewers' scores, not our own measurements. How we score
Comfort*
Estimate: only 2 reviews about comfort (fewer than the 3 we need, so never above 8) 8/10How comfy and steady it sits on your head.
2 reviews on comfort, e.g. "stays secure and stable on my forehead without having to over-tighten the strap, with little to no bounce on steep, rocky descents".
Ease of use*
Reviewers' average 8/10How easy the buttons, modes and lock are, with gloves too.
3 reviews on ease of use, e.g. "When you're wearing gloves they're not the easiest, which is a shame as it's likely that's when you'll need them most!".
Reviewers disagree on this.
In short

Weaknesses

- Short at full power: 4.5 hours at 750 lumens (Black Diamond's figure)
- No AAA backup: it runs on the built-in rechargeable battery only
- 114 g puts it in the 110–149 g weight band
