I've been carrying my G2X Pro this week at work. I really like that light. If Surefire would make it to accept an 18650 I would carry it more. I use a 16650 in it.
The E2 head assy's (integrated) reflector does fine with focusing traditional incan tower modules as it should; just not the case with LED tower modules. And according to LF, no matter how hard they've tried in refining its LED towers, maintaining a decently tight beam profile (as with the incans) is just not possible.Could you explain why they don’t maintain good focus with a tower module? Maybe show a beam shot of what you are talking about if it’s not too much trouble? You have me curious now.

I have two of such towers modules: one with 319a (4000K) and another one with XPG2 (S5). The latter seems to focus better than the former with the said head assy, but the same is not true with the former. Problem is, the latter module is custom made (BTO) only. So with the former, while the beam profile is very usable at short range, at long range the hotspot simply becomes too weak to cut through the distance, and hence rendered useless.

The light from an incandescent bulb originates from a single point, and shoots light in 360 degrees in a sphere, and the reflector gathers it from all angles and shoots it forward.
When we stick an LED on a little stalk and slide it into the spot where a bulb was, the little dome on the LED projects most of the light forward and not a lot is caught by the reflector unless the reflector is setup specifically to gather light from an LED instead of a bulb. Sometimes people use thin washers or shims to adjust the standoff so the tower module doesn't protrude as far into the reflector and more of the light hits the sides to project forward.
I got my hands on a Surefire Millennium Turbohead and tried it on my M3 (essentially making it an M3T) with a Lumens Factory LED tower module and was unimpressed. A setup like a Malkoff Hound Dog with its nice deep reflector is specifically made to gather and project the maximum amount of light forward. That's also why we see a lot of optics on LED lights instead of reflectors.

LPC, or Low Profile Carry made by Thyrm.That's pretty snazzy! What clips are they? I could use one for my 6P.

It comes with an aluminum washer and O-ring to fit different models. It actually fits the MD2 the best, using no extra parts or spacers.
The 6P needs an O-ring to take up the slack in the gap between the tail cap and body.
The Surefire L2 is awesome! I had one for awhile. Great light to keep in your bag as it's good at just about everything. My work bag used to be a Maxpedition Sitka before I took to carrying my laptop all the time (now it's a Hazard4 Switchback, same sling-style, but larger and with a built in laptop compartment), and I'd always have the L2 in the outer pocket. At one point, I had an L2, A2 and L1, the 2-stage trifecta. The A2 and L2 have long since been sold. Great to hear the old Surefires still getting love.I did for about 4 years, a stock L2. Used it for work & as an EDC. Great light, still is as it's tied to my EDC backpack as I type this. It often finds it's self on/in my GO bag depending on my mood & needs. It's on the pack now because of the 123a batteries being more consistent as a power source in cold (freezing) and below temps. Not a true EDC as it's only with me if I have the pack w/me which is often but not always
It doesn’t. As seen in the comparison photo below, the LPC does not completely shroud the button.Does the Thyrm LPC allow a light having a z41 to tailstand?
Hi, is that a max vision and did the switchback fit without using washers?
