While many lights have more throw than the CL1H, I don't think any single-die LEDs are brighter overall: that is, have more throw+spill combined (lumens).
I think the CL1H is your best choice. It is clearly brighter than others in its class: after all, it is being run at 1.2A, while competitors don't go over 1A. This of course leads to a shorter runtime, but I don't think that is an issue, as a) it still runs for almost an hour, b) it is still extremely well regulated, and c) the CL1H is very well heatsinked, so the extra heat generated does not cause a problem.
The brightest CL1H is the CL1H v3 3SD Q5. The v2 is an older model not available any more, and has some annoying flaws. The 1SD and 2SD pills are equally bright - the difference is the number of modes (first number in name). Q5 is the brightest LED currently available from Dereelight. They recently had a run of R2s, but they were not premium tint, and are sold out. The CL1Hs whose names start with M take more battery types, but a) they run at 1.1A, so are not a bright, and b) are very well regulated, but cannot acheive the D versions' regulation with any battery type.
You stated that you want a light under 150mm (CL1H v3 is 140mm), so I will not go into the "throwers." The WT1 is out of your range - it is 154mm long. The shorter of the two new U2s is far out of your range at 165mm. A far better alternative to the WT1 is the Tiablo MA6. I have one, and it definitely works as a "wow light." It is 5mm shorter than the WT1 and only 1mm wider, putting it in your length range. It throws far better than the WT1, and has multiple modes with a great UI. The UI is excellent for everyday use, but cannot be turned on for less than a second, as clicking within 1 second will change modes.
You may find that while the CL1H is pocketable, it isn't all that comfortable in your pocket. You will probably be even more amazed with some of the tiny lights only 1/4 the CL1H's volume, and half as bright. Two very bright (and relatively cost effective) EDCs are the Fenix P2D and the Nitecore Defender Infinity.
PS - lightreviews, linked earlier, really is an amazingly complete site to look through. Be sure to note spill lux readings as well as center lux readings.
