      Comments about Princeton Tec EOS LED Headlamp:

      GREAT LAMP BUT IF I HAD A CHOICE I WOULD BUY THE BLACK DIAMOND SPOT. ITS A BIT LIGHTER AND I LIKE HOW IT ILLUMINATES. THE PROBLEM IS THERE IS NO SENSOR THAT SHOWS YOU WHEN THE BATTERY IS LOW. IT WILL JUST GET DIM AND EVENTUALLY GO OUT. ONCE I WENT CAVING WITH MY FRIEND JEFF IN FLAGSTAFF AND AFTER A FULL DAY WE DID ONE MORE TRAVERSE DOWN A SMALL SLOT WE HAD TO TURN BACK CAUSE IT WENT OUT IT TOOK A WHILE TO GET THE BATTERIES IN AGAIN BUT WHEN WE DID I WONT LIE THE SUCKER IS BRIGHT BUT THE LED WILL ONLY LIGHT UP WHAT YOUR POINTED AT. I LIKE THAT ITS ADJUSTABLE. GOOD WHEN YOUR HIKING OUT AT NIGHT. VERY SIMPLE AND LONG LIFE. ITS ALSO H2O PROOF TO A METER SO DONT WORRY ABOUT THE RAIN. FITS NICELY UNDER MY ELIOS VISION HELMET FROM PETZL TOO. BUT I LIKED IT SO MUCH I BOUGHT 3

        Comments about Princeton Tec EOS LED Headlamp:

        Great headlamp. I highly recommend LED lights with regulated power supplies, like this one. My old Petzl just got dimmer and dimmer as the battery wore down. The Princeton Tec's regulation ensures that the power output remains much more constant, so the light will be bright even if the battery is low.

        Comments about Princeton Tec EOS LED Headlamp:

        The three intensities plus the flashing light meet all of my requirements. I use the various intensities for DIY projects requiring spotlight for my work. The blinking feature is great for walks since it floods the pathway with light but conserves energy. It's also handy as a flashlight.

          I have about 5 Princeton lights and have no complaints but this one now is the main one I use. I typically keep it on a lower level to conserve battery but when you need the light it is there.

          Comments about Princeton Tec EOS LED Headlamp:

          This light is bright! And it stays bright for quite a long time. Unlike some others this model has a voltage regulator in it; so, it tends to stay brighter longer. My only complaint is that the light comes on at the brightest setting, which can really ruin your night vision if you're not expecting it. Wish it started out low and then got brighter. This is a great light.

                I used this headlamp as my main flashlight backpacking and was very pleased with it. It wears comfortably and the light is strong and effective. I have not been able to test it for battery life yet, but I have high expectations for its durability. I am looking forward to using this lamp on my next trip.
