The Story of SC31 Family

I’ve come full circle. Back to simple is better. I don’t, and never did use any of the andruil functions other than ramp. The last convoy I ordered is a simple off/on 4 mode. Works perfect.

SFT40 needs a deeper reflector, otherwise it can't produce long-distance light.

we don't have plan for that, if you like 18350 tube, SF40 is a good choice for you.

Is the strobe on the SC31T constant or alternating frequency?
It would be better if the turbo and strobe mode were also memorized.

I would like to see a single tail e-switch version of the SC31 Pro with Anduril 2.

Yup, me too!

You mean with an inner tube like a FW3A?

You guys make an amazing product and are always innovative

Yes, it would need an inner tube. It would be very popular.

Maybe Sofirn could pull it off better than Lumintop did. Seems like a lot of moving parts just to get a tail E switch though. It would be nice if Sofirn made a slick little 18650 light under 100mm long with charging.

SC31T strobe is alternating frequency. SC31pro will switch to Anduril2 when it's the right time.

A 10cm long 18650 light? I am think about it. TIR len to make head short, tail E switch makes short tail. But I am not sure if it can be under 10cm.

You are losing sales to light painting photographers by using alternating frequency strobes. Constant frequency is more preferable.

A SC31 Pro but with a tail e-switch instead of side switch would be very popular.

Probably not. The shortest 18650 lights I got are the MH20s (there are some shorter ones, but not by much), but it’s a side-clicky. Any tailcap-with-switch eats way too much length with the movable parts and spring.

You’re almost at 7cm just with the cell and contacts. Add springs at both ends, make allowances for protected cells and even button-tops, and it’s even more. Even a shallow TIR is at least 1cm high. Add a pillar/shelf for the LED+pcb, a driver, etc., and it’s a tight fit.

The MH20 gets away with some length-trimming because it needs button-top cells, as the contact patch on the driver is just a shallow Au-plated button, not a spring, so that’s only a few mm vs lots more for a compressed spring at the driver.

I think some Folomovs were just a few mm shorter, but can’t recall details.

A switch in the tail? Probably not easy.

The Folomovs had terrible heat handling due to the small size. Same goes for FW series. Small dimensions and low thermal mass isn’t a good thing.

What need these SC lights is have Constant current drivers without pwm and the possibility of having firefly mode under 0.1lm

Doesn’t stop people from bitching about it. They want 5000lm “sustainable” turbo from something the size of an S2+ while staying cool to the touch, and having 3hr runtime at those levels, too. Oh, let’s not forget massive throw from such a small reflector, with “usable spill”. :person_facepalming:

I’d prefer side switch. Wowtac has one, A6. Shorten the SC31pro tail cap and make it a TIR. A6 is 98.5mm long, sustains 400 lumens. I know you can do it. :+1:

Just received my green SC31 pro from aliexpress, wondering if Sofirn makes a green color 18350 tube for this? I couldn’t find one.

Nope. I’ve been down this road with Sofirn. Your only option is to buy a green SP40 which comes with the green 18350 tube.

Thanks for the fast answer.

So they have the colored tubes but won’t sell them! :expressionless: But they sell colored magnet caps for it :expressionless:
