Functional quality at a good price

This BD headlamp is a steal at STP. For a similar Petzl or Princeton Tec you'll pay 2-4x what this one costs. Changing batteries is easy, and the headlamp has multiple intensity and directional adjustments. I've used it camping, hiking, and even for some work around the house when I had to kill p...

  • Good product but a little annoying
    Verified Buyer Reviewed by Rosey from Sebastopol, CA on Friday, September 1, 2017
    Obviously a well-made product, very efficient on batteries, but in my opinion there are just too many settings and it's hard to keep them straight. But it's easy to just ignore them and go for the ones you need- I just use the bright setting and the red setting.
  • awesome

    I decided to upgrade my headlamp - my old one was difficult to turn on and off, and it didn't have the red light feature. This one is absolutely fantastic, especially for the price. It has a many modes and is super easy to operate. It's not too heavy and is comfortable to wear. Highly recommended!!
  • Comfortable, functional

    Wanted a compact head lump with red light. Read the instructions! There is a special storage mode which helps prevent accidental turn-on in a pack. Very comfortable to wear. Bought two more as gifts. Great value. Using Sanyo eneloop NiMH rechargeables.
  • Really nice headlamp, red LED is great

    I wanted specifically a 'headlump' with red LED for night vision, long battery life, and less bug attraction. I'm glad I read the instructions since there is a non-obvious lock mode which helps prevent accidental turn-on when in a bag or pack. I used it on a week long river trio with one set of NiMH Eneloop rechargeables and it has plenty of battery left. I'd like to buy another. Strap is comfortable too, nothing hard to poke into your head after a while as some designs do.
  • Great

    Love this head light. Small compact with multiple modes with a dimming feature that is quite nice to conserve battery. It does have a lot of modes and only one button with different click sequences to activate them. If you think this would be annoying to you this is not the light for you.

  • “How do batteries get inserted, do the + ends go up or down?”
    Asked by Mac dumey from Missouri on 12/24/2015 9:16:12 PM
    • The batteries go in lengthwise in this item. There are + and - indications in the item.

  • “The image of the Plum band light shows a fourth, small bulb down and to left of central bulb. What is that. No red lens, correct? Several reviewers mention liking the red light option.”
    Asked by North Country Mom from New Hampshire on 12/3/2014 3:53:01 AM
    • I returned my Cosmo and got the Spot instead as it had better specs and the build appeared better. But, to answer your question more directly, I believe that the little bulb to which you refer is a small red light for reading, etc. Since I no longer have the exact model I cannot be sure.

    • I have the green model of this headlamp, but I think the light modes are the same for both. Yes, the small bulb on the bottom left is the red "night vision" light. You have to hold the button down for a few seconds to get the red light to come on, and if you then very quickly press the button twice the red light will also flash. To get it back to the white light, you hold down the button for a couple seconds. It is a little tricky to get the red light to come on and then turn it off, but it is a nice option if needed.

  • “Is it OK to get this wet.”
    Asked by Biker Chris from California on 5/12/2013 5:47:43 PM
    • The headlamp is protected against splashing or sprayed water from any angle.

  • “PREFACE: In the headlamp market, "regulated" means an on-board computer chip regulates the voltage so light stays fairly consistent in brightness over about half the battery life, after which voltage regulation ceases and the brightness gradually dims until dead. If this device is "regulated", the manual and/or packaging will use that exact term as defined. QUESTION: Is this device "regulated"?”

    • This is not a regulated headlamp.
