    Comments about Princeton Tec EOS LED Headlamp:

    Before I purchased the Princeton Tec EOS, I compared it to several models that were on the market and the EOS was and is still is one of the lightest and brightes LED headlamps in it's class. I have used the EOS for about two years now and even currently there is no headlamp I think is better for general outdoor use. The things that make it a good headlamp are: the power output is regulated, uses commonly found AAA batteries, easy to use with gloves and most importantly it is one of the few lightweight headlamps on the market that is waterproof. The only thing that would make it better would be if teh EOS had a top strap.

    Bottom Line Yes, I would recommend this to a friend

    Comments about Princeton Tec EOS LED Headlamp:

    I've been using two Petzl Tikka XP and two Princeton Tec EOS for outdoor activities and on the job in a research lab during the past ~3 years. Both of them deliver excellent lighting and battery lifetimes. However, both Princeton cracked at the same spot on the housing after less than one year of use. The metal screw/thread and the plastic housing don't go well together and what looks like a reliable way to seal the housing on the first glance turns out to be a weak spot after a while. First the waterproofness went and now the cracks have to be duct taped so you don't cut your fingers when switching the light. In comparison both Petzls still work fine.

      Comments about Princeton Tec EOS LED Headlamp:

      I bought the EOS headlamp as a replacement for the Quest headlamp and have no complaints. Its very light, has 3 different beams plus a strobe if needed for emergency times and with the LED the batteries seem to last extremely long. I take it everywhere, from day hikes to multi-day kayaking trips.

        Comments about Princeton Tec EOS LED Headlamp:

        We have many trails that are day and now night accessible with the Princeton Eos. Moreover, I frequently walk our two Samoyeds at night. The light reflects the eyes of our forest denizens and has kept us from many close encounters with skunks. Our way is clearly lit and many fellow hikers have asked the manufacturer's name so they might purchase one. Mine held up for 5 years and recently failed after taking a major blow affecting the switch. Bought another and have no regrets. Great product!

        • Hiking

        Comments about Princeton Tec EOS LED Headlamp:

        I got this light because of its stronger LED and semi-light weight, but mostly for the water resistance. I do adventure races a few times a year and water is hopefully always involved. I also (personal preference) don't like a strap going over the top of my head, just around it like a headband.

        I have kayaked in some serious swells during a rainstorm on Lake Mead with this light and it never faltered. I have also swam at night with it. Every now and then it would go under the water with me a foot or two with no problems. I have had it for almost two years now and the beam is still bright, centered and goes a good distance. Great for biking at night. I can also use the light underneath my helmet (no over the head strap).

        The platic housing used for adjusting the angle of the light from your forehead is also well made. I bought a different brand light for my wife and the plastic housing cracked after a couple uses.

        I would definitely recommend this lamp to others

        Comments about Princeton Tec EOS LED Headlamp:

        If you are looking for a bright light that can also last a long time this is the light for you. However be very careful with it and don’t put it at the bottom of your backpack because if you set your backpack down on a hard surface it could break the plastic and water-resistant ability of the light. I have gone through two of these lights and I love them just don’t be too rough with the headlamp it could crack. Great for rainy weather and seeing far distances.

          This is the BEST headlamp that I have found!!! I have had it for two years and have found no faults!!! This thing is bright, three settings and excellent battery life. Still not sure what this whole, "regulated" thing means but I guess it is important to some people.

              Comments about Princeton Tec EOS LED Headlamp:

              Ok so this headlamp is really a good deal, however im a big adventurer and it took a lot of abuse. somehow i ended up with 3 of them. so i kept one with my backpacking gear, canyoneering gear and one in my jeep.

              its adjustable and sturdy, but my next purchase will be something more water proof, i canyoneer a lot which means im rappelling down waterfalls and not all are huge and raging most are a steady stream, it said its waterproof to a meter so i purchased a few, and they worked excellent its first two seasons, then i started haveing problems with corrosion inside and the buttons not working, i think im gonna trade up to the BD Spot, and another one which can withsatand more water, i have one left and i love it but when i tried to contact princeton tech they fell Short on CS, and really couldnt help me nor could suggest other options.

              this really is a great lamp, i will recommend it just because i know what kind of abuse it can handle, its really a great over al lamp.

              Got this for a steal [...]. It is VERY bright and operates on easy to find and install AAA batteries. the straps are easy to adjust and the tilt mechanism is simple to use. My only compliant is that it's a big large but an awesome value given the brightness and price that I paid.
