List of budget lights with constant current drivers?

I have been thinking of the M21C non U as I have read great things about it’s driver.

Thank you for the options!

EDIT: I didn’t realize the M21C-U was the same cost as the non-U. I prefer side switch lights.

The T9R - Man how do you use that light though? I guess if you just never look directly at it, you can maybe forget how ugly it is?

Also I can’t understand why they have a FET mode on the NOV-MU. Already someone on Reddit has fried emitters.

I thankfully have not fried mine during runtime tests, but I could see that being a concern. I’ll probably never actually use turbo on mine. It’s got a FET because they plopped the exact same driver in several lights without any modifications. Honestly, even if you’re not going make hardware changes, I would probably eliminate the FET channel using a custom config file. But in talking with loneoceans, I don’t think he even knew that the driver was going to be used in something like the NOV-MU. I’m sure he would have gladly tweaked the config if they had approached him about it.

Yeah, he doesn’t like FETs much to begin with, does he?
The driver is just entirely poorly suited to the NOV-MU. 6A is awful low for 21 emitters, but the FET channel wide-open is probably a bit much. Especially with how good 21700s are.

I love DC constant current drivers.
The ones I’m using are Convoy’s new 5A and 6A drivers, ramping drivers, Sofirn SP31, SP32, SP33V2, SP33S, SP35, SC21 and C01S. Furthermore, SP35 and SC21 can operate stably with constant current even with an external power supply from USB (excluding turbo). I use SP33V2 as a lumen standard.

I forgot another important thing.
When Anduril is physically turned on, it always starts with 7135 X1 and there is no PWM (however, manual memory mode is OFF). I often use this brightness regularly. It’s also useful when comparing flashlights.

Is there a list of current Convoys that have the 5a/6a drivers? I realized that the store listings don’t always put it in the title/product description, and I had to message Simon for clarification.

All power sources is measured in watts, but not in rigged flashlight world :smiley:

Armytek flashlights and headlamps…

Convoy driver sold separately on Aliexpress
It is in Accessories (1) of “Convoy flashlight Store”.

The convoy driver mentioned here is not the 5A driver in the s2+, right?

That’s just a linear driver, no buck or boost?

My complements to OP, best question posted on this forum in a long time.

Great replies also.

Convoy’s 5A and 6A drivers are perfectly linear. It seems to be mainly used for S2 +.
Interesting is the 4-mode driver for the Optimus T2, which works as a constant current boost driver (0.5A) for eneloop and as PWM (1.5A) for lithium-ion batteries.

Perfectly linear? I’m assuming you’re referring to the output…

Still doesn’t answer my question. Is it a buck, boost, or does it just burn off the voltage (linear drop off)?

They're linear drivers. The 22mm 8A driver is the only buck driver from Convoy for 3v leds.

Convoy’s 5A, 6A, and ramping drivers are constant current driven by current sense resistors, operational amplifiers and FETs. Since it is a linear drop-off, the control is output as heat. Not buck or boost.

Any updates regarding the “list”?

The buck driver is used in what convoy lights?

Have there been any new lights released with a constant current driver since last year? I’m only aware of TS22 and SC33.

Convoy has an s3 now with 719a or B35AM emitters plus several other 719a lights that are using boost drivers.

I’ve tried most Convoy models, but I’m unfamiliar with the S3. Is it basically an S2+ or is there a clear difference with it in some way?
