The adaptive lighting works well and is uber-useful. the programmable aspect is great too. It took me a few rounds to get the settings the way i wanted them. Advice along those lines: you can set-up 5 different levels of lighting (using different power for the wide beam and the long beam). I broke it down to 20, 40, 60, 80, 100 initially and this wasn't useful. there isn't much difference between 60 and 100 (it's all just really really bright). Instead, I now have my 1st setting on like 1% (use it for finding things in the trunk of the car or inside a tent), then like 5% which is enough to get you around (walking in a campground or on in your driveway), then 10% which is enough to run with on a relatively smooth road. then 50% which will light up the whole street. then 100% just to be obnoxious.
By weight, this is heaver than some other lights. It's lighter than the danged AAA batteries though. Doesn't matter because it's well-weighted and doesn't;t feel like much on your head. My other lights (battery and light in the front), I always had to wear with a hat - like a shelf. This one I wear with a light bandana which saves me some weight and also also the light to come down to my feet and is not blocked (eclipsed) by the bill of the hat.
Seriously, the first tie i ran with this in a group setting t night, the people I cane up behind thought I was a car.

This one does it all. It is a smart headlamp that is equally at home on your head or helmet. It senses what you are doing and adjusts the light to meet the demand. If you are on a trail after dark, the long distance beam is on. Stop to check the map & GPS and the lamp dims to the level needed for that close-up work. Petzl has created "reactive lighting" and has done it very well, indeed.
The headlamp has a rechargeable battery (N.B. it comes with the battery disconnected - you have to open the battery case and plug in the battery before you charge it for the first time). The battery charges from the ubiquitous USB connector (a male connector is part of the battery case). Your battery life can be very short - less than 2 hrs - if your use requires constant highest light output (way brighter than any other headlamp I've ever used, including a Carbide Lamp!), or it may exceed 50 hours of continuous use in the average camping/hiking situation. A slick feature is the ability to replace the rechargeable battery with two AAA cells (at a loss of some brightness and automatic functions) if your rechargeable battery is discharged. Given the ubiquitious USB adaptor for automobiles and backpacking solar panels, switching to standard AAA cells won't be a common choice - but it is nice to have an alternative when necessary!
It gets even better! Petzl has created a program to tweak the headlamp! A free download for Mac & Windows machines, the Petzl application allows you to name your headlamp and the battery, as well as to store up to four (4) "profiles" for your headlamp. The standard is Petzl's "Multi-activites" profile. You can choose to include three other profiles (including ones that you create!). Petzl provides the standard as well as: "around-the-house", "bivouac", "Mountaineering", "Orienteering Race", "Trekking / Hiking", and "Caving/Spelunking".
The only activity I don't believe this headlamp is appropriate for is open-water / white-water rafting & kayaking. It is not "submerged" waterproof though it handled a brief afternoon mountain downpour without harm.
It's fairly pricey until you factor in the cost of disposable batteries. If you use your headlamp often and frequently have to adjust the light level (as I always do when tying on a new fly) your battery costs will offset the price in six months, or less.
It's comfortable and stable beyond what I was hoping. Every other headlamp I've used bounces around while I'm running (it's possible I'm not all that graceful) but this one is comfortable and never feels like it's slipping.
I have few negative things to say about the light (beside the price) but it is worth mentioning that the reactive lighting only seems useful in the forest. Part of my run takes me through a town and I always turn the reactive lighting off for that part of the run. Reflective stripes, signs and even license plates, street lamps, store fronts, all make the lighting turn to its lowest setting. That's not necessarily bad, but it seems like my light is flickering sometimes because of all the light sources and reflective surfaces. Again, the light is doing what it's supposed to, but I really only see the benefit when I'm in rural or backcountry settings.
The computer interface is useful but it's not as intuitive as it could be. On my Windows 7 computer it has been difficult to get installed properly and I suspect someone with minimal computer skills might decide it's not worth the trouble.
I haven't had any problems in the first few weeks, but I worry about the durability of the tiny little clip that holds the battery/USB interface in. You have to bend a thin piece of plastic to snap the battery out. If that clip breaks I think the whole light will be useless, and I'll actually have to replace a large part of the light's framework.
I love that the light locks in the off position for when it gets thrown into a backpack. However, I hate how hard I have to turn the knob to unlock the light. I feel like I'm going to break it every time.
In the end, I'd buy this light again, but I'd probably still lie to people about how much I paid. It's a lot of fun, I have complete confidence while running in the dark and it was worth it to me for that.
