I received today, and just tested outside the Eagletac SX25L3 MTG2.
Overall it is a very solid and well designed light.
If you're in the market for just one very solid premium quality, but not very overpriced light, I would recommend it.
If you're a flashaholic and want to try something new. This is not the light for you.
The reason being is it's a light that is a jack of all trades, but master of none.
In terms of output, given the ratings of my other flashlights I feel confident that the the ~2400 lumen rating is accurate.
In terms of throw I'd say it's edges out the SRK slightly.
In terms of flood it loses to the SRK.
In terms of beam profile, there is a better defined nice round beam, with no artifacts. The transition from hotspot to spill is noticeable, but not at all jarring.
The UI is excellent. The build quality superb.
I highly suggest ordering the Kit version of this light because it comes with a second tailcap that has a rear switch. This rear switch allows you to control the light in the same exact way from the rear as with the side button.
Both switches are electronic, not mechanic, as such there has to be some standby drain, but given it's 3x18650 I highly doubt it will ever be an issue.
It will fit even the longest protected panasonic 3400mAh batteries easily.
I'd rate the light design as a 9/10. There is really no good reason why it can't be somewhat smaller and shorter.
I do have two gripes about the "Kit" while the second tailcap with switch is by itself worth it (imho) the holster, and the color filters are not.
The holster is open topped with just a plastic rib to hold the light in place. I find it awkward to take it out, and put it back in. I also don't find it to be all that secure.
The color filters are plastic, and not of a high quality. In order to install one you have to take off the stainless steel bezel, thereby exposing the lens. It is also easy to cross thread and ruin the threading on the plastic lens retaining ring.
It would have been a simple matter to extend the bezel by another 2mm, extend the threading of the plastic filter retainer by 2mm, and allow the filter to be screwed on top of and into the steel bezel.
All in all, a very good solid light, but I can't wait to get it modded, and will be thinking hard about whether to keep the dome on, or get rid of it. On the one hand the dome helps with the overall output somewhat. On the other hand, without the dome, the light would have more throw, but still with a rather wide beam. Decisions decisions :undecided:
