The OAL and increased brightness are neat, but virtually no one will notice any difference in durability or brightness. I love the shape, build quality, user interface, magnetic tailcap, and battery indicators (except their dimness). The beam, clip, and charging are fine. I wish there were a ZWB2 filter over the UV and that the indicators were brighter. I strongly dislike how Turbo is inaccessible below 3 bars of battery.
This is a weird release. The light is good, and calling it “Ultra” makes it sound markedly better than Arkfeld Pro, but it’s not. This is another color option for Arkfeld Pro with a $20 price bump. I wonder how much of that cost went into the goofy coin. If price isn’t a concern and you like the updated aesthetic, go for it. If you like Arkfeld Pro’s color options and price better, you won’t miss out on anything if you choose the Pro version.
