BLACK DIAMOND Storm 500-R Headlamp, Black

Tiene un error que cambia automático cuando se mueve un poquito , cambia las intensidades y modos de luz

Solid headlamp. Have had several black diamond headlamps however the latch for the battery compartment breaks after much use. A rechargeable unit eliminates this problem. Easy to use weatherproof, very bright.

I would’ve preferred these to be less expensive for the weight and narrower headband width. But the functionalities and the ability to recharge is worth it. I use these mainly for early morning and late evening dog walks and checking out what’s going on in the woods next to my house with the highbeams at night! 🙂 The charge status lights are a little annoying, but they only stay on for a few seconds. Hopefully the next version will have them on top of the headlamp. There’s no need for them to be on the bottom edge shining in your view because you’re not checking on them while they’re on your head! Can’t speak to the long-term charge duration, but I’ve been using them every day for about an hour over several weeks and haven’t had to charge yet.

According to the specs this has a 2,400mah battery. If we generously assume they’re using top-of-the-line LED tech, you can produce about 100 lumens per watt. So at 2.4AH * 3.7v for a lithum battery, their battery can theoretically store ~9wh of energy, slightly less than an iPhone battery. The theoretical maximum amount of light that can produce is 500lm for ~2hr, or 300lm ~3hr, or 100lm for ~9hr, etc.

Take Petzl’s Actik Core light for example, which has a similar battery and package size to the Storm 500-R: 600lm for 2hr, 100lm for 7hr, 7lm for 100hr, seems very reasonable.

There is no way black diamond can >3x these specs in the same overall volume and weight, it’s not physically possible with battery tech today.

And yet… on the 500-R box Black Diamond somehow claims theirs can do 500lm for 7h, 250lm for 19hr, or 6lm for 350h, which would require a battery >21wh, impossible to fit into a headlamp that size. The “ANSI burn time” spec supposedly measures the burn time until 10% of initial output, so they only way they can achieve these numbers is if they *rapidly* drop the brightness from the initial e.g. 250lm down to like 50lm for the majority of the runtime.

Don’t support products that blatantly mislead consumers with bogus specifications. The fact that Black Diamond chose to mislead people this much on a headlight makes me question their integrity and think twice about buying climbing gear or anything else safety-critical from them, I cannot fathom why an otherwise reputable company would burn their brand like this.

To top it all off, when I bought this light I played around with it for like 20min and the electronics promptly failed. It got stuck showing one battery status light and became entirely unresponsive (and it wasn’t in locked mode or any other mode). I had to wait a week for the battery to die before it seemingly rebooted and started responding to button presses again. The charging port flap is also questionably waterproof, I wouldn’t trust it to reliably stay closed on an intense climb or bicycle ride in the rain.

Allonger le fils de recharge serait une bonne chose

Super bright, comfortable, great color light options to not blind others while at camp with a long battery life. This is my second one Iv bought. Not because there was anything wrong with my first but i like to have a back up while hunting. Knowing one is stashed and fully charged is a good feeling.
