When I needed to get a new light for Survival Run Nicaragua in early 2016, I spent quite a bit of time looking at the current options, and decided that the Black Diamond Icon is hands-down the best for what I do….18-36 hour runs and some mountaineering. (You are referred to my earlier article for a more generalized discussion of the characteristics that should be considered.)
It is very bright at 320 lumens, but can be dimmed to a spark. There are brighter lights (but not many since the 2017 version of the Icon bumped up to 500 lumens from the 320 lumen 2016 version), but you sacrifice an unacceptable amount of battery life. A lot of people will tell you do don’t need this amount of light….and 90% of the time they’re right… but in difficult navigation and very technical trails you will be happy to have more lumens (“my gun is too big” never said any cowboy ever!)
It’s battery life is good. You get 9.4hrs on bright according to the Outdoor Gear Lab review, with which you can see 80m. Life goes to the rafters as you dim the light… days and days. This is plenty for running a full winter night, given you will likely only use the brightest setting half the time at most.
The light pattern is good… wide bright, with only moderate dimming to the edges. Lots of peripheral light, but the pattern is not wide enough to light up you eye lashes (trust me…that sucks).
It uses AA cells. You can get these anywhere in the world. Rechargeable, non-swappable lights are convenient….until you forget to charge them or need to go longer than they can deliver or they accidentally turn on. And many hard races require you carry spare batteries. If you do feel the need for a rechargeable light, Black Diamond offers one as an add-on product.
There is a lock on the light, so it won’t accidentally turn on. Genius.
Sure it’s heavier than many lights….but the straps are good and it carries with great balance. And, apart from for the very smallest ladies, 232g isn’t really that much… HTFU.
It is adequately waterproof for almost any occasion. I’ve spent quite a while swimming in mine. Rain won’t ever be an issue. For serious canyoneering you may want more….but that doesn’t sound like your goal. Sure, it’s expensive (USD100) but compare that to how much you spend on race fees, fuel to the races, food, bribes for your crew….and it is irrelevantly cheap if it gives you a slightly better race. Also, this is far less than the top-end lights from Petzl or Light in Motion.
Cute extra: red LEDs so you don’t wake your significant other when trying to sneak out for an early training session.
