Convoy S21B with 10A driver

Is the Convoy S21B with SFT40 and 10A buck driver a stupid and dangerous idea?

I understand it will get very hot but is it still safe for short bursts (less than a minute) at 100%

I am new to this forum and I also have very basic knowledge about flashlights so please excuse me if I ask stupid and unreasonable questions

Fwiw I’ve been running an sft40 with 12A FET driver in an L21b. Larger host for sure, but so far hasn’t posed any problems.

That’s a great thing to hear now I’m convinced to try the Convoy 10A driver with the SFT40.

I actually prefer the M21B host but I wanted a compact flashlight to show off to my coworkers who mostly only use AA flashlights.

Thanks for the info

If I may ask, besides Convoy, is there any other brand that gives us the option to choose the LED and driver we want?

For budget flashlights, Convoy has the most choices by far.
Other great budget brands are Sofirn and Wurkkos, but they don’t offer nearly as many options.
I don’t know much about more expensive brands, or if you’re interested in spending more money. :money_mouth_face:

Emisar/Noctigon (referred to as Hanklights) also offer loads of driver/emitter options, they are enthusiast-oriented lights that perform and cost a notch above Convoy/Sofirn/Wurkkos, for lights in the same form factor.

I just checked out Hanklight and I really like their dual and triple channel flashlights

Have you considered the sft25r? I’ve one fitted in a S21G titanium host with 8A buck, it gets rather hot after prolonged use at 35%, but not unbearably hot. I recon it throw slightly farther than the sft40 with the same reflector cup and driver, so there’s enough wow factor for the colleagues, if not more :smiley: and more reasonable power wise for the size of the host.
