My Ultra arrived today.
The beam pattern really is as different from the standard E2D LED Defender as I've been led to believe. This is a good thing, since it differentiates it further from the other TIR'd lights.
The body and tailcap are fully E-series compatible which I was expecting/hoping to be the case. The knurling may be slightly more aggressive than my other like new E2L and L4 bodies. There is a second spring attached to the head.
For those interested in aesthetics, the anodizing matches quite well between body and tail. The head has a noticeably darker color, when viewed in really good light. It's very utilitarian compared to the natural anodizing of the E2L, L4, and LX2. I'm also very glad they've included the two-way clip on this iteration, since I've standardized on bezel down for all carry lights.
The tint is definitely greener than I would prefer, but this isn't much of a surprise. I've always really liked the white tints of my LX2 and E2D LED.
As expected, the level switching is performed in the head. I prefer the 15 lumen low of the LX2 over the 5 lumen low of the E2D LED. I'll know more about this low after it gets dark enough to see more than just the spot.
It slaughtered my LX2's reading at one meter of 9.30 Klux by delivering 18.36 Klux. Both lights were run off fresh CR123 cells. Oh ya, I'll be taking more measurements at 100 yards with this sucker in the near future.
