Great little pivoting LED headlamp
Verified Buyer Reviewed by Kurt from WA on Friday, December 12, 2014
I finally broke down and bought this headlamp to replace my big ol' clunky Petzl that used those monster flat pack batteries. I was hesitant going to LED because I knew some of them couldn't really throw a beam very far. This is not one of those headlamps! Good strong beam that really cuts through t... Read More

  • Headlamp

    Good quality. Bulkier than many other models but easy to use.
  • Nice headlamp but not very durable
    Reviewed by Samples from colorado on Friday, September 2, 2016
    It's a good little unit that is powerful enough for typical camping or night walking duties and seems to have long battery life. Only problem is that the mount broke on the light body where it pivots. Likely broke in my pack. The lamp has been on less than 15 trips, so was expecting it to hold up better than it has.

    Would buy it again if I was only using it to walk around the neighborhood.
  • Good lamp

    Nice and bright, only issue is the strobe function that happens before you can turn it off is a little startling, even when you know it's next.
  • Great Light
    Verified Buyer Reviewed by yellowdaylily from NH on Friday, February 19, 2016
    Our first headlamp gave out so I ordered this one. So glad I did. The light options are great with the brightest light allowing us to shine it into the woods on a night walk and see what just made that sound! The band that goes around the head is stronger feeling and easier to adjusts. The only thing missing is the red light that the other one had.
  • Powerful Headlamp
    Verified Buyer Reviewed by Mill Valley Mum from Mill Valley CA on Sunday, January 4, 2015
    I love this sturdy lamp. It's my go to, for sure. The three different settings of steady light are quite different, making them all useful.

    These are the three reasons why I gave it a 4 instead of 5: 1. It's a bit heavier than the other Princetons I have. 2. It burns batteries quickly on can tell when the batteries are waning because the most powerful setting starts to dim and then all three are about the same brightness as the lowest setting after a while and 3. I love the vertical mechanism for focusing the beam up or down during reading or other close jobs. It's not a sturdy design on that part of the lamp. Mine eventually broke right off. Naturally, STP was great about sending me a new one because it was under six months (so STP gets 5 out of 5).

  • “Does this also take lithium batteries?”
    Asked by the piano lady from Washington on 5/2/2015 4:15:31 PM
    • Hi Piano Lady - I believe the lamp takes only regular batteries, but I'm not 100% sure. I love the headlamp - I use it for camping and reading to my son at bedtime.

  • “On the black band/orange housing light, is red light an option? How does it work?”
    Asked by North Country Mom from New Hampshire on 12/3/2014 3:48:37 AM
    • There is no red light. 3 brightness settings and one flashing. I used this light a ton this summer for trail running, camping, and hunting. Loved it, especially for the price.
      Answered on 12/3/2014 7:36:38 AM by Sheldon from Colorado
    • the head band light is controlled in a handy area in the front. You can make it flash or be steady. The red light is also controlled there.
      we camped out on the desert for 10 days and this light was the best. Night on the desert without facilities, well, I say no more.
