I have one of the new 8A buck drivers with 12 mode group firmware and I’ve had this happen once as well.

seems like spring bypass is not very high quality, after short time it just ripped off on all 3 s21a which I had

I guess its because of low quaility insulation on that cable used for bypass, which will become just too stiff(plastic like, instead of rubber…) due to heat damage

anyone can chip in whether there are any safety concerns when the bypass cable snaps?

Probably not. But, the light can be run at a lower level. I have remade the bypass with a larger wire due to this happening on some of my S21As, too. At first, I was surprised it happened because the stock wire looked ok.

I dont think so, you will just lose few lumens on higher levels

I measured 21.48mm with my calipers.  I use Samsung INR21700-48G which fit just fine.

Is the SST40 of this review the 5000K version ? It seems like by the picture

Just got mine in, does anyone know of a clip that fits around the light and is captured by the tailcap?

In this style…

The Convoy S21A can be had with either the “4 modes” driver or the “12 groups” driver.

In the “12 groups” driver instruction it is mentioned: “BTW, do not leave the light in config mode for long period of time, because it will wear out the driver’s memory faster.”

Does that mean that Convoy lights with the “4 modes” driver will last longer than those with “12 groups” driver ?

Thank you in advance.

Probably best asking in a thread that Convoy owner Simon posts in regularly about the driver ‘wearing out’.

yes, IF you plan on leaving the light in config mode… !

If you use it like a light and reconfigure it only occasionally I cant see you being able to see any meaningful difference in driver life
