I have not been impressed with the overall fit and finish of the lamp, but it gets the job done.
As might be expected, the battery pack is quite large. Four AA batteries, kind of large. I bought this model because a lot of my other emergency gear runs on AA batteries, and I have a good solar charger. That sort of ties me into that form factor. Sadly, there are not many good AA options, as they headlamps all run on either AAAs or CR123 lithium batteries that cost as much as a mortgage payment.
This light does get quite bright, and the focusing ability functions fairly well. However, the LED housing gets very hot, and mind you, is stuck to your forehead. The actual focus dial feels very cheap and doesn't stop at either end of its travel, which makes you feel like you've broken the thing. If you adjust it past either end of the adjustment, you might lose zero and end up thinking, again, you've broken it. I feel like this could have been better designed.
I will be using it until I can afford to replace it, at which point it will be left in my garage instead of in my emergency supplies.
