Therefore, having survival gear that can entertain a range of climates is what you should aim for, and with the Storm headlamp, it is what you will get. You can’t predict the time nor the place of an emergency. It is an excellent choice if for all day and night outdoor activities, and therefore would be an ideal choice to keep in your survival kit should you encounter any future emergencies. The Black Diamond Storm headlamp is a robust and waterproof headlamp that offers survivalists with eight different lighting options, including RGB night vision mode, and has a peak of 350 lumens.

Mine is the opposite the whine is loudest at full power.Black Diamond Storm Headlamp Product Review Also, somebody said they heard the whine when dimming. Just sitting here web searching about the high pitched whine ringing. My new 500 has it, but I haven't been outside with it because it's raining hard out there. My previous Icon 320 Lumen also did not have the whine. My wife has the Storm and it does not have the issue (EDIT: I later found out it does hum, but I can't hear it when on my head, see my next comment).
Black diamond storm headlamp problems upgrade#
It would though be nice to upgrade as the lumen output on newer models has jumped quite a bit since I bought the ReVolt. If what Black Diamond and user Jordan Whitley say is true that this is normal, and it bothers you that much, I'd return it for a refund and potentially buy from another company.ĭoes anyone know if the new Black Diamond Storm head lamp has this same issue? Is this only an issue with the recent Icon models? My three year old Black Diamond ReVolt doesn't do this at all and has been quite reliable. I am hoping that I'm an outlier and an exchange would resolve (or nearly resolve) the issue. not sure how I'd like that after exposure to it for long hours. Indoors it's quite loud but even when I am outdoors and using it, just walking along it sounds like I had a loud blast go off in my ear and they are ringing from it. I am still torn on whether to return or try to exchange as my headlamp is quite loud in all settings on the single bulb function. Thats the game with Switch Mode Power Supplies. You should be able to start at a low brightness, and gradually increase the brightness and you'll hear that noise get higher pitched and higher pitched until you reach a point where you cannot hear the switching at all, since the switching is back out of the audible range and the brightness will continue to increase.Not really a problem, just kind of a design issue and annoying. It may sound like a high pitch whine, but it's actually the power supply switching very quickly at a certain speed (in the KHz normally).
However occasionally (and it depends on the design), when the light is dimmed, those pulses can end up in the upper end of the audible range, so on some lower settings, the switching frequency has gotten so low that you can hear the switching taking place. In full brightness, or even half brightness and above, the switching is so far out of the audible range (in the MHz) that no one would ever be able to hear it. The LED is actually switching so fast that your eyes can't actually notice it, however when the LED is dimmed very low, the wavelength (pulse-width) begins to decrease more and more, so the OFF time is longer than the ON time in each cycle. They make that whining noise because Black Diamond uses a Pulse Width Modulation controller to take care of the LED dimming and brightness.
