You should be talking about Sichuan Province in China, which is far away from my city. 
Thank you Simon for the offer.
Nevertheless, it would be nice if it was also available in your shop.
If it becomes available T3 with MAO coating I would definitely take advantage of it.
There’s an M4U listed in the new items, any news on what this is? Is it just an M3 with integrated charging?
It’s actually a different, older model. The M4U head is slightly smaller, plus it’s Micro-USB compared to the M3 which has no integrated charging, and the M3-C which has USB-C charging.
M4U also uses a mechanical side switch and Biscotti firmware, which is quite unique. I can’t think of any other lights from an enthusiast-grade manufacturer that use a mechanical switch on the side.
That’s hilarious
M21G XHP70.3 HI 2*21700 flashlight available
2022/9/6
M21G
M21G with batteries
How many cd M21G XHP70.3?
what type of driver does the M21G use?
Nice, now I want a M21F with XHP70.3 HI 5000K. Please, make it happen Simon! Or even the XHP50.3 HI with the same 6V 5A driver.
GT-FC40 uses a 12V 4A boost driver. XHP70.3-HI uses a 6V 8A linear driver.
But the output current is only 5A
I know, what I really want if the XHP50.3 HI 5000K-5700K in the M21F. While not as throwy it should have higher output than the SFT40 and better tint.
8A linear or 5A how Simon stated earlier?
@tactical_grizzly, I don’t think it uses a linear driver for the 6V LED lmao.
It probably uses a buck driver.
Simon, why can't we have in the LED options a Yinding 5050 or G50 as Haikelite calls it which is an excellent throw LED with a luminance higher than Osram CULPM1.TG and an output higher than 2000 lumens?
[quota=Fedtro]
Simon, perché non possiamo avere nelle opzioni LED un Yinding 5050 o un G50 come lo chiama Haikelite che è un eccellente LED a focale con una luminanza superiore a Osram CULPM1.TG e un'uscita superiore a 2000 lumen?

By now the new generation of Chinese LEDs is equal if not superior even to Cree or Luminus so you who are an innovator could try to make some products and see how customers respond ...
It could be buck driver also. I would estimate that it could regulate 8A output to about 6.4 battery volts before it drops off. Then only lower modes.
12V boost driver would work for XHP70.3 HI also and regulate max output for whole battery range, but Simon would need to source 12V mcpcb’s with electrically insulated thermal pad. GT-FC40 mcpcb wouldn’t work.
M21G uses an 8A driver for XHP70.3-HI as stated on the product page.
The 5A driver Simon is referring to here is in M21F, not M21G.
I could be wrong about it being linear. That would be awesome if that’s the case! Is there some technical reason a linear driver would not work?
Right now I believe it’s linear because of the price point, output current, the fact that Simon usually (not always) uses linear drivers where emitter & cell voltages are similar, and this light’s similarity to L6 (which uses a linear driver with XHP70.2 as far as I’m aware).
Simon, can you tell us whether M21G uses a Buck or Linear driver with XHP70.3-HI?
Simon confirmed below that it is a BUCK driver!
Hi Simon, I would like to buy B35AM 4500K but would prefer side switch and USB-C charging, for example as in my favorite Convoy host, M21F.
Is that a good idea wrt reflector/driver design consideration, and if so, could a one off be done? Thank you.
