The light was great and very bright and I just couldnt pass it up for the price I found it at. But I recently sold it for the new Petzl MYO RXP and I couldnt be happier. The Brunton's beam is just too narrow. I got caught on a hike at night on a pretty rocky and technical trail, and the narrow beam just didnt show enough of the trail. It really needs diffuser of some kind. Plus, by having the 4 AA's on your head, its alittle heavier than normal. Nothing to unbearable but it really needs a third strap to keep it from slipping..It comes with a separate battery pack for C-batteries but that was just to heavy to carry.

This is a good headlamp. It is solid and the removable battery packs are a nice touch. It is very bright, though it doesn't seem to have the same illuminating power as the xenon bulb headlamps I've used in the past (although batteries last many times longer when running an LED than they do with a xenon bulb). I have not used this lamp enough to comment on the battery life, but the mechanics and ergonomics of it are good, and it is lightweight, comfortable, and sturdy.

Great headlamp. Comfortable to wear, and very bright. I was a bit surprised by this light when I turned it on. Compared to some of my previous Black Diamond's this one is right up there and compared to some models, even brighter than them. It's of average weight with the four batteries, however I think this would be really heavy and even uncomfortable with the attached C batteries. The regular batteries last quite long. My only complaint is with the focus of the light. It is somewhat of a narrow beam, so if you are looking for a wider beam for night-hiking this might not be the perfect light for you. Great for cave explorers.

I've used the L3 for 2 years now after my other expensive (Primus) headlamp broke and this L3 exceeds my expectations. Originally I had been skeptical of Brunton brand headlamps but after reading other reviews I changed my opinion. This is about the brightest led headlamp you can get besides the ridiculously expensive L5 lamp. The L3 really is impressively bright and has incredible battery life. The only thing wrong here is the price.

I use it three times in a 8 to 10 hours night trips (include Via-Ferata and rock climbing in total darkness!)
and the light is so stong that you can see the next marking on the trail in total darkness!
(a 100meter ahead). and I useing the same batterys that came with the headlamp!
this is the strongs headlamp I ever used. and I used three stong models of Black Diamond (Moonlight, Nightray and Helion).
this is the best!

Best light I have ever used in every way. Not too heavy for the head, amazing battery life, EXTREMELY bright for any light and very impressive considering it is an LED. Highly recommended is you want a stellar light and not ULTRA expensive.
