Initial impressions of the H600Fd III. 1000x times better than the POS Fenix headband. Was surprised at how comfortable it is and much prefer the top strap going from front to back rather than side to side.
Tint is very nice. Near identical to my ~4700K SC62w, my $1 CCT measuring app shows 4750K on H1 and H2B and 4500K on M1 and M2A which pretty much lines up with what user maukka measured in his awesome review. (yay 1 dollar lol) Not too cool by any means, but wouldn't want to go cooler. Slightly cooler than all of my Nichia 219b lights, did not compare CRI but CRI does seem better compared with my SC62w.
Output...man, it's hard comparing a frosted lens side by side with a regular lens. I guess maybe since the frosted lens is more diffuse and lacks that hotspot, it's not going to look quite as bright, but I believe ZL specs. Very bright and just awesome though.
I never knew how useful a quality headlamp with a good beam could be until now. I wore it for awhile last night, and it just works so well and very comfortable too which I was surprised at. I've been holding lights in my mouth or halfway tail standing them and blinding myself for so long when working on something, this is literally a treat now. When Zebralight comes out with a 90+ CRI lamp with even better runtime and output, I'm in, no question, take my money now. The H600Fd III is a 5 star, home run.
