This may be because of the platform review, I just tried it, the UK page should be able to display normally.
XHP50.3 HI can be installed in S21G
The four LEDs are connected in parallel.
Does S21G use the same reflector as S21A/S21B?

Hi Simon, the new M1 models with XHP70.3 HI seems very enticing to me. Do you have plan to produce some other colored shell of M1? I like the idea of 18650 XHP70.3 with moderate sized optics. M1 ticks all the boxes apart from the plain black aluminum shell. Even a grey or sand colored would be better for more variety.

Adding to this - I’d love an M1 18350 tube. It would be somewhat similar in size to a KR1. That light just fits perfectly in my hand and has a great “feel” to it (albeit it’s naturally shorter so the 18650 KR1 would probably be similar in length to an 18350 M1).
I’m tempted to do a mod to the M1 tube to shorten it for an 18350 but I’d much rather have a stock 18350 tube

Simon, what would be the main changes / improvements between an aluminum S21G vs S21B? Also, will it be easy to install TIRs in the S21G? Thanks.

I understand and I like this design. If the head of the light was copper with a titanium bezel and body that would be amazing!

Hey Simon I know you were considering discontinuing the M1 when current stock runs out, but a few different colors and an 18350 tube might be just the thing to revitalize this model! Please consider it.
Thanks

Yes! There is a lot of appeal of a small light with big output. M1 with XHP70.3 ticks a lot of boxes.
1 Thank
yes, the same
Sorry, the previous reply was wrong.
This reflector is special in that it is tapered rather than cylindrical.Otherwise it cannot be installed.
Only the 23.3mm TIR lens is suitable for S21G, but the glass lens needs to be removed,So the head is not waterproof.

The stainless steel buttons of the S21G have been improved over the previous ones.You can directly replace the light switch with the original ordinary switch.
Because the thread of the S21G flashlight is also conductive, you can’t completely de-energize the switch by hanging the tail loose one turn.
If you don’t use the flashlight for a long time, please remove the battery from the flashlight.
