    Strap your Princeton Tec Fuel 4 70 Lumen Headlamp to your head and comb the campsite for enough firewood to get you through another better-left-untold story and the rest of the whiskey. This bright, versatile light may be small, but it can throw out some serious light from its compact frame.

    • 70 lumens reach up to 39 meters so you can see from one end of camp to the other
    • Focused wide beam is bright up close but drops enough light on the sides to let you use your peripheral vision
    • Tight design means this lamp weighs in at at a very packable 2.75 ounces
    • Single-arm asymmetrical arm bracket shines light wherever you need it without having to angle your head
    • Oversize power button is easy to find in the dark or with gloves on
    • 146 hour burn time (on the low setting) keeps you out of the dark for a long time
    • Water-resistant construction means this light won't die if you get caught in the rain

    Decent Headlamp

    • Familiarity: I've used it several times

    I've used this a few times since purchase and it's worked as expected as a headlamp. I haven't (yet? luckily?) had the battery door issues other reviewers have mentioned.

    My favorite part was that this COMES WITH the batteries - so you're good to go with one purchase! Nothing worse than getting new equipment and then having to make another visit to the store before you can actually use it!

    Excellent headlamp

    • Familiarity: I've put it through the wringer

    I picked this up on sale and use it regularly, for field purposes it was ultimately replaced when I upgraded to the Princeton Tec Tactical Quad Headlamp. I made the move to the Quad solely for the fact that it had interchangeable filters. Say red for night activity when not wishing to disturb wild life (an excellent choice for truly low impact camping) but also the green filter for reading topo maps at night as yellow or even clear light can obscure contour lines. Back to the light at hand, it's bright and its light. With some replacement batteries the fuel could easily pass as the only light source you'd need on a back country trip. Though it may not be in my pack anymore, it is still what I wear when working in dark corners of the basement or finishing up late night yard work. It has a permanent home in the glove box of my truck.

    Excellent headlamp

    Let There Be Light

    • Familiarity: I've put it through the wringer

    This is a decent head lamp for the money...especially when you find it on sale for $20. My wife and I both rock the Fuel and have never had an issue. This is a straight forward light. We have worn them when the rain was pretty heavy with no issue. These things are great to have around the house when the power goes out too because of a storm.

    Like some of the reviews here have mentioned. The battery door could break, but for me that has not been an issue, and if it will break I know that P-Tec will take care of me!

    Light and Bright...with a few kinks

    • Familiarity: I've put it through the wringer

    Decent all around camp/backpacking light. Brightness is good enough for me although I wouldn't try to do any serious cave spelunking or anything like that. Battery life is awesome and really saves this lamp from a lower rating. The main flaw is, of course, the dreaded battery door. It broke on me during a camping trip through Utah a couple months ago and really frustrated me. However, princeton tec has amazing customer service (another redeeming feature) and sent me out not one but 10 replacement battery doors! I'll definitely be set for life, but it is a bit of an inconvenience that I now have to carry around a spare battery door in case the inevitable happens.

    I think its worth the price (especially if you can pick it up off SAC) but be prepared because the battery door will most likely break on you sometime in the future.

    Reilly. Did they send you another functional light and needlenose pliers with the 10 doors to fix your light in the dark? Sending out extra doors isnt warranty and speaks of obviously known design defect. The entire line of Princeton Tec lamps that use this door desigm is worthless if you need to depend on your ewuipment.

    Nice little lite

    • Familiarity: I've used it several times

    A great little light that fits most usage. Girlfriend bought one of these on a deal at the GoPro games this june and they let her make a custom color combo for about 20 bucks! Still has that great princeton tec warranty. Have not tested the weather-ability of this piece yet though.

    From the Lab: FUEL Headlamp

    FUEL puts out 70 lumens via four 5mm LEDs. This headlamp keeps its stable asymmetrical single arm bracket and easy to find power button. FUEL runs for up to 146 hours on three AAA batteries.

    Decent output, poor construction

    • Familiarity: I've put it through the wringer

    I had one of these for a couple years, and thought it was pretty good most of the time; it had pretty good output, was light and easy to operate; but the battery door was ridiculously hard to open, then it broke off

    my battery doorbroke quick too...

    Mine broke as well. Called up Princeton Tec and they sent me, free of charge, not one but 10 (yes ten) extra battery doors and pins...a little overkill but I'd say I'm set for life haha.

    Good lamp, questionable durability.

    • Familiarity: I've put it through the wringer

    As a few of the reviews have already stated, this lamp doesn't stand up to much and the battery door has now broken on mine. In addition to that, it now has a short somewhere in the wiring and works intermittently. Haven't had any major drops and was well taken care of during use.

    Battery door breaks

    • Familiarity: I've used it several times

    The door to the battery broke off after using it for 2 months. It's useless now unless I duct-tape it shut. I always knew this would eventually happen, so I wasn't surprised when it did.

    Other wise, great light. Used the blinking mode for bicycling. Would like it to have a red mode. Give it 3 stars for breaking.

    way too bright

    • Familiarity: I've put it through the wringer

    If you are searching for something you lost in the forest at night, this is your headlamp. If you are trying to blind your friends at night, this is your headlamp. I can't even point this at the bill of my hat on low and have it be as dim as most other headlamps. There are three brightness settings and all of them are stronger than most headlamps. Just don't buy this if you don't want something ultra powerful.

    From the lab: PTec FUEL Headlap

    Updated for 2012, putting out 70 lumens via four 5mm LEDs. The stable asymmetrical single arm bracket and easy to find button remain. Runs for up to 146 hours on three AAA batteries.
