Light Your World With The New BD 1/2 Watt Cosmos Headlamp

Post by blogger | August 30, 2007      

To rock your world you might need to light it first. This excellent new model Cosmo headlamp from Black Diamond flew in over the transom a few days ago — it’s impressive.

The object at hand — or in this case, on the head. Louie reduces his carbon footprint by turning all the house lights off. Headlamps as a carbon offset? You bet.

Available in November, this new version of the Cosmo model uses a single 1/2 watt LED for the spotlight mode (1st in the industry), instead of one watt’s worth of LED. Result is better battery life with a super-bright beam that’s just slightly weaker than the 1 watt version. How? A good reflector is key to getting light out of devices like this — I learned that from automotive lighting.

Additional moderated and less “spot” light is provided by a pair of smaller LEDs to the sides of the middle larger one. You change brightness settings with half-presses of the on/off button — eight settings in all including that wonderfully obnoxious but potentially useful flashing mode.

    Hey Lou:

    Looks promising. Right now I use the BD Xenix IQ which I’ve been really happy with. What kind and how batteries does the new Cosmo use?

    And what’s with the sticker hanging off of that laptop? Say it isn’t so!

    I applaud Louie for having a Teletips sticker on his computer, it shows open mindedness. However I do question his diet….what is that a Hostess Zinger in his hand? I hope he’s not training for any upcoming rando races.

    Teletips? Just testing you guys and seeing if you’re really looking at our photos!

    The Cosmo uses 3 AAA. I’d rather it was 2 AA but that’s life…

    Am I the only one who likes to walk around the house at night with a headlamp on? There so handy! I have the BD Spot and I love it. I tested it with about 4 other like models and it was by far the best.

    Nice eye for the Hostess products Carl.

    I think that’s some kind of mongo burrito, but he could have substituted it for a Zinger while I was memorizing the poetry on the Teletips sticker.

    What’s making me chuckle at the moment is serendipity. Mitch over at Teletips published an embarrassingly flattering intro to a video interview with me, and I swear on my ancestor’s graves that I didn’t know anything about his plans on writing that even though the Teletips sticker appeared on WildSnow at approximately the same time it showed up on Teletips. As they say, vibes… At any rate, the interview and stuff are here if anyone wants to check it out: (defunct link removed)

    Perhaps more tomorrow about this.

    Carl, the Teletips sticker didn’t quite make it to the computer, but I think it’s destined for an even more honored location: the Nalgene.

    Nice eye Lynn (I know that one is glass, but we won’t go into that). You are very correct, the sticker is floating there….not on the computer per say….just sort of sitting there…..almost as if it was staged by the photographer to “grease the flex point” if you will. However I will say that not sticking is not committing….so until I see it on Louie’s Nalgene I’ll remain a skeptic. I doubt that there is any room on Louie’s Nalgene anyhow…my guess that it is 100% full of stickers with no sign of Lexan. If I had to guess the stickers on Louie’s Nalgene I’d say NOLS, Cloudveil, Marmot, Black Diamond, BCA, and Wildsnow. But wait, I remember a post maybe a year ago when Lou denounced the Nalgene and sang the praises of old pop bottles…maybe Louie doesn’t even have a Nalgene. If you read this entire ramble than I think you better reconsider your work load. Is it almost time for ski season yet?
