All I had to do was trim the three little tabs at the front of the optic holder, and fix the new reflector in place with a dab of epoxy. The beam is an 80-degree PURE FLOOD. Very nice! It's like a 1/2-power Zebralight, at 1/2 the price.
The beam has no hotspot whatsoever, but there are a few tiny artifacts. They're not noticible in actual use, unless you're using the headlamp to hunt white walls

Reason: updated old links
edit: Princeton Tec spells the name "Eos", with just the "E" capitalized. However, I've seen a number of retailers (and people, including myself) habitually type it in all capital letters, for some reason.

Do you find the hard transition from light to dark annoying at all? I'm using the Carclo 10170 in my current headlamp build and am planning on diffusing it for a softer edge.
Yes it can be annoying, but the transition from light to dark with the 10170 is the same as with any other reflector. I think diffusing the beam might work well, as long as you don't lose any noticeable output.
I put a Carclo 15degree (medium in the 6, 15, 30 degree range offered) 20mm Luxeon optic (from Photonfanatic a couple of years ago) in my Eos. I have a high CRI SSC in it now. It has a decent spot, but massive corona tapering all the way out to the edge of the spill which tapers off without a hard ege cut-off. It has some artifacts only seen on white wall. I keep the Eos even though I have a ZL H30 due to it's more useful light distribution.
