I'm also a Fenix guy, but have considered an Olight headlamp. I just haven't found one that I'm willing to spend my money on. I'm just not a fan of some of the features they're headlamps have to offer and like so many flashlight/headlamp companies, they try and hook you with the "unreal" output on turbo, only to realize it only lasts for 30 seconds or a minute.
Luckily for you, you were gifted one to try and see if you like it.
I did recently purchase an Acebeam H17 from Vinh with 519A 4500K LEDs and am really liking it so far.
