Also did S2+ M3 M21A M21B.

I’ll risk it, much improvement in output?

300-400lm I think – I’m basing it off this:

I gained around 300 lumen with an R050 on the SST40.

The FT03 is still brighter, its driven quite hard

Overaggressive throttling? Could you or someone else explain this a little bit better?

In what reviews I spotted of the SST40 based S21A, when you engage Turbo Mode, it almost immediately starts stepping down, pretty much negating anything useful of that mode.

Wow, so bad?

I have to replace the driver in my nephew's S2+, torch predominantly used with the short tube, guess I won't mess with thermal throttling in that one. The other driver, though, is another story.

Good info. I just ordered a few of these and I’m sure I will do this mod.

These drivers with the stepped modes look like constant current linear mode FET drivers like led4power’s. Is the other ‘ramping’ driver from convoy mentioned above also this type of driver? The description and UI seem strange. Is the current limited to 8A?
