Beam Comparison - Headlamp


Battery Life vs. Beam Distance - the above graph shows how beam distance at the brightest setting degrades as battery life runs down. We use the ANSI FL-1 battery run-time spec, which says run-time for the high mode is finished when brightness degrades 90% from its initial value. The ANSI standard is more stringent than what headlamp manufacturers use. They consider high mode run-time still OK so long as there's enough battery to produce light as bright as a candle placed 2 meters away (0.25 lux). We think the manufacturer's approach is deceptive and misleads consumers to believe the high output mode produces a long-distance beam much longer than it actually does.

                                       Black Diamond Icon: we measured the maximum beam distance as 82 meters and the ANSI battery run time for the high setting as 9.4 hours.
                                       Black Diamond Storm: we measured the maximum beam distance as 78 meters and the ANSI battery run time for the high setting as 7.8 hours.

Black Diamond Icon
The Black Diamond Storm was updated in 2016 to with improved optics  56% more lumens (250 vs. 160 before)  and is more waterproof IPX67. One thing we don't like about this new version is that one of the buckles on the strap  see right side above  faces in and if you have a tight strap that buckle is annoying.

Pros Bright, wide spotlight, clear/smooth optics, long battery life, robust designGood trail finding and close proximity beam, easy to use, waterproof
Cons Heavy, bulky, and expensiveMore expensive and heavier than the higher scoring Spot
Bottom Line Very bright with a wide beam, this model is bulky and heavy with an even heavier price tag.Ease-of-use and storm readiness are this model's strong suits, while it dips in performance when compared with the Spot.
