PETZL E+LITE Headlamp - Ultra-Compact Emergency 50 Lumen Headlamp, Designed for Hiking, Climbing, Running, and Camping

I just got this lamp, so I can’t possibly report on battery life or long term durability. But I can tell you why I instantly fell in love with this thing!REASON FOR PURCHASE: For exactly what it is - an emergency back-up light source.ACTIVITY: Casual backpacking - never on trail after darkMy primary light source is a rechargeable Fenix headlamp, which has more than enough burn time to get me through a multi-day backpacking trip. However, I was still carrying a spare charged battery just in case……That spare battery weighs 0.7 oz. It has no other function. Just hangs out….This E+lite, on the other hand, only weighs 0.9 oz. (without the case). AND it can actually DO stuff!*It’s a stand alone spare lamp. And it even has a fold out stand if you like.*It has safety strobe modes in both white and red (which my primary lamp does not).*AND it has a whistle! A whistle that is smaller, louder, and clearer than the 0.3 oz whistle I was already carrying on my pack. And if you’ll notice, the red slider button on the whistle is actually a key that opens the battery compartment! Are you “blown away” yet?*By golly, you could probably even use the headband to hog tie a chipmunk or something! The possibilities are endless!From now on I’ll be leaving that free-loading spare battery at home… It was sorta’ needy anyway…always getting recharged before each trip… Nagging me… It won’t be lonely though, it can hang out with my retired old weak whistle, and their new friend, the Petzl case. Now the case is clever in it’s own way. It has a handy belt loop, even sports a cute illustration of how to signal SOS or OK. It weighs 0.7 oz. I’ll keep it for kayak camping some day. As the lid is held on tightly with a rubber band, so it’s splash proof. But it won’t be necessary for storing the lamp in a handy spot in my pack, as the included lamp stand is also made to fold over and protect the face of the lamp.A great deal of thought and detail went into this little lamp. The switch, while different, is easy to operate. Of course it is not super bright, but it’s not made for trail finding or shining deer. It’s a very adequate SPARE. And the use of pill batteries means it has a long shelf life and it can LIVE in my pack without worry of it leaking battery acid. Always packed and ready to go, and looking out for me in case one day I forget to recharge my regular lamp before a trip, or even forget to pack it!

I bought this for an emergency kit that I'm trying to keep as light weight as possible without sacrificing too much capability. Out of all the lights I personally inspected, this one met my expectations. It weighs in at 0.9oz for the headlight and strap. With the included case it weighs 1.6oz total. The light is compact and offers 2 brightness levels(15lm and 50lm) a red light(not the brightest but usable) and 2 flashing modes(one white, one red) honestly your headlight doesn't need the power of the sun. The 50lm output is sufficient for moving in the dark. Even the 15lm output will light up a dark room enough move around without tripping. The run time of this light is also great considering it takes 2 CR2032 batteries. The batteries aren't the cheapest, but I'm not complaining. When you want the best you have to pay for it, and in my opinion this is the best ultralight headlamp period!

B4 you buy back up batteries...It takes 2 CR2032 NOT CR2s as listed..Its light and bright and has an O ring in the battery compartment to keep it watertight. The long narrow head strap is comfortable hanging around the neck keeping it accessible. Finally the double OFF switch is convenient so you don't have to cycle through all the White lights to get to the Red lens in the dark

I am a backpacker, so weight is very important... but so is performance. I decided to upgrade my first generation e-Lite, and I am glad I did. My primary motivation was the additional brightness. My old 3 LED models still works great after years of service and I expect this one will do the same.This rugged light delivers enough light for anything you need in the deep woods. The switch design is easy to operate, even in winter. It is almost impossible to accidentally switch the light on in your pack (hate when that happens). I loop this light onto my hammock ridge line for convenient access and hammock lighting.Pros:Lightweight, functional, decent amount of light, red/night mode, waterroof case, good battery lifeCons:Requires 2032 batteries, not as bright as heavy headlamps

I purchased the Petzl after posting a query here, to which I received very helpful feedback from a half-dozen owners who have used and reviewed the product. (Thanks again, folks.) I was looking for a headlamp to use indoors as a reading light, and I wasn't sure how well this would serve the purpose. Turns out that it suits my needs quite well. The advice I got from most who responded to my query was that the high setting would likely be too bright, but the lower mode should be okay. Well, maybe my old tired eyes are weaker than theirs, but I've ended up using the high setting somewhat more than the low. The e+Lite is not perfect as a book light, but for me it's better than expected. Its light weight makes it easy and pleasant to wear, the angle of view is generally good, and the illumination is adequate (often in both modes). I'm a satisfied buyer.
