    Great little headlamp for the money. Very light on the head and the beam is very usable, no weird artifacts and nice compromise between spot and flood. Brightness is just about perfect. I’m using it every single day morning and night feeding animals and dealing with firewood, and the battery lasts me a few days before a recharge. Lithium battery so far works great in the cold, which is not the case for alkaline or nimh. I wish you could swap in different batteries on the fly, but thats not really what this headlamp is for. The micro-usb charging is very convenient, seems like I always have at least one other device that also runs on this cable, so its easy to find.

    Don’t love the built-in battery or more precisely the fact I can’t carry a backup with me. What I did was bought a small portable battery charger to throw in my back on camping trips because I prefer this light over others for most activities. So my opinion is that this headlamp is great for general purpose (around camp, work around the house, walk the dog, short runs). Do not buy this if you are running for longer distances (longer than an hour) or if you are using for trail running (no throw down the trail). Good hiking light because of battery indicator, good runtimes, and comfortable. I didn’t think I would use the 400 lumen boost, but it really is a nice option to have and I have used it to extend that reach of light to see the things making noise beyond 25 yard mark. This would be a 5 star for general activities, but I gave it 4 stars because I would prefer that it have the ability to carry a backup.

    On a side note, I highly recommend another headlamp from Fenix for runners, HM50R. The HM50R is also is a great hiking headlamp. Buy a backup rechargeable battery for the HM50R (ARB-L16-700) and easy to carry with you to always have a backup in a light that has great throw and spill beam with power.
