Beamshots:
Spillbeam comparison at ~.5 meters from a wall. Both lights are running on 2xCR123A with OP reflector, on Hi. The WT1 is focussed for maximum throw.

Beam observations:
The Fenix T1 produces one of the smoothest beam profiles I’ve seen for a Cree emitter, while still maintaining considerable throw.
The Regal WT1 still shows signs of rings even with the OP reflector installed, so I recommend running it on the smooth reflector for max throw.
My first edition WT1 has a slightly misaligned emitter, leading a darker semi-circular region on one side of the hotspot. I’ve seen this before on other lights, and I think it stems from not having the emitter/star sitting perfectly flat against the heatsink. My second edition WT1 is well centered.
The Fenix T1 is brighter overall, with a broader hotspot and wider spillbeam than the WT1. However, The WT1 has a more focused hotspot with further throw.
Note that the WT1 can be slightly defocused into a broader hotspot by turning the head counter-clockwise relative to the body tube.
Overall Output:
For overall output comparisons, here are the results of a "ceiling-bounce" test in a small windowless room, with my light meter on the floor near the base of the light (which is shining upward in candle-mode). Both lights are on primaries with OP textured reflectors installed (and as always, the WT1 is focussed for maximum throw):
Regal WT1 (1st Edition, OP): 7.0 lux
Fenix T1: 9.2 lux
As you can see, the Fenix T1 is definitely putting out a lot of light.Note that the second generation WT1 should be out soon (and Dealer claims to have increased output by ~10%). UPDATE: Just received my new second edition WT1, and my lightbox tells me its overall output has increased by ~13% compared to the earlier version.
Throw/Runtime Measurement Method:
Throw values are the square-root of Lux measurements taken at 1m using a light meter. Note that my lightmeter tends to report lower absolute values than most, but I have verified it is linearly responsive over the range of intensities in question.

RCR x 2 on low: 6,200 Lux
CR123A x 2 on high: 10,650 Lux

CR123A x 1 on high: 6,650 Lux
CR123A x 1 on med: 1,850 Lux
CR123A x 1 on low: 530 Lux
Regal WT1 (2nd Edition) - Q5 - Smooth Reflector
18650 x 1 on high: 13,350 Lux
CR123A x 2 on high: 13,400 Lux
Throw observations:
The second edition Regal WT1 throws about ~13% further than the original WT1 (both on the smooth reflector). Overall output (as measured by my light milk carton lightbox) also shows ~13% increase for this new WT1.
Even the first edition Regal WT1 throws further than the Fenix T1. Although with the OP textured reflector installed in the WT1, the throw is just slightly higher than the T1 (at least as measured by lux @1m).
The Fenix T1 is an impressive thrower for its size, although the beam is bit more diffused with a wider hotspot than any of the dedicated “thrower” lights out there.
I’ve added the single battery D-mini Q2 Digital with smooth reflector for comparison purposes. As you can see, it doesn’t throw quite as far as the T1/WT1, but with a Q5 emitter it should be pretty much equivalent to the OP-textured T1/WT1.
Runtimes:
These runtimes charts are different from my other reviews - they represent throw, not overall output. Since my home-made milk carton lightbox doesn't accurately capture overall output on these intense throwers, I have adjusted all my relative output numbers to initial throw (measured as the squareroot of Lux @1m). This allows you to directly compare the relative throw of each light over time on the graphs below (although you can't directly compare these graphs with my other reviews).

Note: For the runtimes, the WT1 is using the smooth reflector for maximum throw. With the OP reflector installed, initial throw is pretty similar to the Fenix T1 (as determined by lux @1m).
Runtime observations:
Just a reminder again: the Fenix T1 produces more overall output than the first edition Regal WT1 on primary CR123A. The graphs above are throw-adjusted to lux @1m with the smooth WT1 reflector. With the OP reflector in the WT1, the initial portion of the curve would look about the same as the T1.
The second edition WT1 has ~13% more output and throw than the first edition, but with similar runtime.
On Hi, the Regal WT1 has very flat regulation on primaries, and a typical decay pattern on 18650.
On Hi, the Fenix T1 also has very flat regulation on primaries, with a nice long moon mode.
Both lights performed as expected on 2xRCR - flat output, but short runtime.
On Low, the current-controlled Fenix T1 lasted considerably longer than the the resistored-low mode of the WT1 (as expected). Note that although the WT1 throws farther than the T1 on low, their overall output on primaries is actually similar (again, the runtime graphs and lux numbers above relate to throw, not overall output).

全是歪歪扭扭的洋文:lol
凑合着看呗。基本上没问题。 t1的橘面 过渡自然 实用不错.
wt1聚焦好 全是歪歪扭扭的洋文:lol 也不帮忙翻译好:lol 看起来很累的 :lol :lol :lol :lol 自己顶顶。
[ 本帖最后由 伊莱克斯 于 2008-1-19 22:20 编辑 ] wt1光斑要好，亮度高时间久呀。 WT1的主要优势是聚光和续航。图表很有参考价值。 看不懂:Q 看图就能知道个很大概了 回楼上：
Regal WT1 (1st Edition) 第一版 就是标题说的旧版
Regal WT1 (2st Edition) 第二版 就是现在卖的新版
新版电路有所改进。亮度提升。
