Can anyone post beams hits comparing this to the k40m, tk75, or other larger lights? I don’t have any of these “dream lights” and curious how this compares as I save up.
Got my other two. All four had excellent finish with no flaws or dust. Sold one, presenting one to a friend tomorrow, gifting one and keeping the best highest amp one for myself. Overall pleased with this purchase. Can’t wait to compare it to some other throwers with optimum weather conditions. Have two builds going one with a SR90 reflector the other is a 1405 with an aspheric lens adapter to 75mm.
I might be able to that later tonight against the K40M and the SD75…
Oh wow, the protected 26F batteries i have fits really tight in the tube! I had to really squeeze the tailcap down quite hard to screw it back down
And nearly blinded when shined on a beige wall a few feet away. Can’t wait to get out to test it’s range later, makes my C8 look floody! Efest 2500 unprotected a slightly loose fit, springs stiff enough to handle recoil. Nice looking case, holster, and remote switch. Packed most excellently with care, thicker plastic outside the box than anything else I’ve ever received, you can tell somebody cared about everything with this light start to finish!

I noticed on mine, there are two resistors - one on another, and top one is flipped over. I was able to take them off one at a time, and both are R100's (0.1 ohm each). So if this produces a true 4.3A at the LED, then:
Adding an R400 should result in 4.84A at the LED
Adding an R300 should result in 5.02A at the LED
In Dale's post of#951, he tried a R050 (should result in 8.6A) that popped the XP-L HI, then a R140 (should result in 5.84A)
This is all theoretical of course, using Ohm's law: "V = I * R", but thinking of trying the R300... I think in almost all buck drivers, there will be a surge/spike that will exceed the stable measured current for a moment, so may be better to be a little conservative.
I just did an emitter current check, with a pair of Panasonic PD’s at 4.06V it showed 4.43A at the emitter, real time.
Ok, the R300 is working, at least so far. From earlier post, stock:
tailcap: 2.43A (on the SANYO GA's - note: maybe not a good reference to determine what's at the LED...)
Throw: 245 kcd (taken at 5m, best # I could see but had difficulty getting a good reading - large jumps with movement, etc.)
Lumens: 1292 @start, 1255 @30 secs (doesn't drop much - good buck driver and good MCPCB/heat sinking)
Now, on KP 3400 protected as-is with the R300 added:
tailcap: 3.24A
Throw: 259 kcd (taken at 5m, little better reading, just not sure...)
Lumens: 1428 @start, 1404 @30 secs (doesn't drop much - good buck driver and good MCPCB/heat sinking)
Gotta try those GA's though, also with the R300 added:
tailcap: 2.87A (on the SANYO GA's @4.21v - note: maybe not a good reference to determine what's at the LED...)
Throw: 255 kcd (taken at 5m, roughly)
Lumens: 1401 @start, 1357 @30 secs (doesn't drop much - good buck driver and good MCPCB/heat sinking)
Ok I got a little better comparison shots than the ones with the rain the other day , with my old version(stock driver and dedomed XM-L2 U2) vs the new GB light…………

Tomorrow I will try something, it seems that the tail current measurement is all over the place, depending on the cells used. I’ll put the loop back on the mcpcb and see how the tail current matches up to emitter current with some different cells. If it’s as it should be, emitter current shouldn’t change much at all.
I can’t view them photos
Not sure why not. The pictures look fine to me.
Well, not fine, but awesome! 
here too.
just a quick test, try to see the topic using a proxy
My tracking info has not changed since November 22 still preparing to ship WTH
:bigsmile: no possibilities to buy one?
I just swapped out the forward clicky switch in favor of a reverse clicky. MUCH better!
I used a small Omten style switch, the spacer works with it and it just required a new rubber boot with the full knob on the inside. I cut a thin slice off (about 1/16”) the knob and it works perfectly. 
Not able to take beamshots today 
I wasn’t out riding so most likely next week I’ll take beam shots against the K40M and SD75
Mine showed up last night, and am truly impressed. While I don’t have a real thrower to compare it to this thing is amazing. This is also my first in series light.
Thanks robo, Amanda and maxtoch for a very well run group buy!
I've been comparing this M24 against my M12 modded with an XPL-HI, and the M24 is definitely better focused, noticeable brighter smaller hot spot. My M12 has been disappointing in throw with the XPL HI. So in the M12, I have a XP/XM adapter that doesn't fit quite tight in the reflector hole (slightly too small so it can move around). Also, the M24's XPL HI is noticeably more inside the reflector. So I sanded down the centering piece and made sure the wires cleared the reflector base - all looked improved/better. Tried it - no difference.
It seems pretty clear the M12's reflector can't get low enough, so the easiest solution would be raising the MCPCB. Before that though, I compared the M12 and M24 reflectors - the M24's reflector is deeper, just by a little. The M24's reflector in the M24 doesn't sit down on it's top lip - it's up against the LED centering piece, as it should be. So I tried the M24 reflector in the M12, and it doesn't fit - near the top lip there a ridge that's not on the M12's reflector, so can't try that.
So it looks like the M24 has been correctly fitted and tweaked for a very good focus with an XPL HI - they did reflector mods and had a custom fitted LED centering piece made. It looks like they made the M24's reflector slightly longer to get the XPL HI further into the reflector to get that tight hot spot. For us modders, we have to do it the hard way, propping up the MCPCB/LED, and playing games with centering... Ugh.
Put that M24 back together and go shine it at something Tom, it will do the job…lol
Just joking, I appreciate you and Dale doing all this testing and letting us know the results in case we ever need the info.
