Sofirn SC31 vs SC31B

LightObsession · 2019-10-26T17:52:42.000Z

Thanks for the comparison.

I should receive my SC31B in two days.

I also would prefer direct access to low from off, but couldn’t pass up the Sofirn combo price for the SC31B.

PiercingTheDarkness · 2019-11-14T09:47:35.000Z

Just thought I’d add that the SC31B lumens tested on High are no greater than ~~760~~ 840 at turn on and ~~720~~ 815 at 30 seconds. This is the cool white version. The 4000K version would be even lower

Modes are Eco, Low, Med, High

Measurements taken a a PVC lumen tube calibrated with maukka lights. Battery used was a Samsung 30Q

Has a firmware bug currently where turning off on Medium switches back on High

Yet again another overrated flashlight from Sofirn. They used to be almost spot on when they first began.

EDIT: cleaned, re-calibrated my equipment and used a new 30Q for the new lumen measurements above.

And yet no one cares about the firmware bug or the “700 lumens” (ill wait for a few more testers to confirm)

It is literally the best deal simple to use USB charging lamp right now

Haters can hate, but ive given a few to “muggles” and they dont give a damn about what some flashaholic thinks

Very few know it’s 700 lumens. It’s good to actually know what you’re buying so you know a genuinely rated light at 1000 lumens is a better upgrade in the future.

I’m trying to do my best fighting a marketplace filled with fake ratings. I’m probably one of the few store owners in the world that sell lights at their true rating.

Bearbreeder · 2019-11-14T05:22:56.000Z

Oh you mean yr test tube numbers that dont mean a thing in the real world?

I mean BLF flashaholics swore up and down that the sc31b has no stepdown, yet they COULDNT EVEN NOTICE a halving of lumens by eye

Sofirn SC31B Step Down Malfunction 18650 Flashlights

The high-to-medium thermal-management timed step-down does not seem to work on my new SP31B. Can someone else who owns this model check theirs to verify my observations? I purchased a Sofirn SC31B during their recent Facebook promotion. It has four levels plus hidden strobe, last-level memory, USB charging, and a selectable button backlight. Very basic interface, a gift for a non-enthusiast friend. Thermal management consists only of a timed step-down from high to medium at three minutes. Upo…

The difference between 700 and 1000 is minimal in real world usage

Maybe you should “go after” convoy for their RECURRING biscotti issue that bins the light into a single mode group

Now THAT is a real firmware issue for the last 3 years, yet convoy keeps selling lights with the issue

https://www.reddit.com/r/flashlight/comments/bymyt3/beware_convoysimon_is_still_selling_drivers_with/

Do you even own a sc31b?

PiercingTheDarkness · 2019-11-14T05:42:50.000Z

The thread you linked to has my video actually showing the test of the step down and lumens lol so that must mean I own one. I also sell them.

I love the Sofirn lights, I sell almost every model but I’m still going to test and post the results.

I’ve heard about that issue on the Convoy’s yet I’ve built and sold over a hundred flashlights using that driver and haven’t seen it myself. Just like ToyKeeper says that it happens randomly on some but not all.

Bearbreeder · 2019-11-14T05:52:39.000Z

Are you gonna go after convoy for their “lies” lumen claims on the s2+ too?

I mean not only is there a firmware issue that locks the light, they only put out around 700 lms too on the 8x7135 despite claiming “1000”

The sofirn “firmware” issue is pretty benign in comparison

Theres been 3+ instances of newly bought s2+ on here and reddit in the past 2 months having this issue

convoy s2 problem LED Flashlights – General Info

I just received a convoy s2 from simon. When I took it out of the package I unscrewed the light to take out the safety paper for the installed batteries. It worked great. Then I unscrewed the flashlight again to look at the insides and get familiar with it. Now it will not turn on unless I unscrew the top half. And even then it will intermittently work. What happened ? I didn’t unscrew the led part only the battery part?..( UPDATE) I have fixed this problem. I was playing with the memory modes a…

Notice how no ones is helping the poor guy

Time for you to take the flamethrower to convoy!!!

Why do you have such a sour attitude? I’m only reporting my tests. How is it different than a review on pros and cons?

You sound like a Sofirn fan boy that can’t handle hearing a little criticism.

Maukka posted that his 3B tint was likely a 4C by mistake which tested 720 lumens on my same light. The Cool white variant tested at 860 - 900 lumens on mine which varied between different builds.

I report on Convoy, Astrolux, BLF among others just the same. I sell heaps of brands.

phouton · 2019-11-14T06:11:56.000Z

BearBreeder I agree the lumen wars are pointless and there’s little real-world value in the 700 lumens vs 1000 lumens. Having said that, it’s valuable for people to know what they’re getting and how a given company’s claims stack up objectively. No need to sling mud at other companies though.

Funtastic Thanks for measuring and reporting, especially since most people have no way to verify the lumen claims.

Bearbreeder · 2019-11-14T06:23:00.000Z

Has anyone confirmed you 700 lumens measurement?

Wake me up when they do

Yr lumens measurements dont really matter too much for real word usage

What DOES matter is the actual graph itself (regulated or not) and actual runtimes

And testing for LVP, and making sure the charger terminates properly and doesnt trickle

This vid matters much more than a test tube number

Its amazing how certain companies get a pass here

Convoy for their biscotti issue, and their “send you a driver” warranty fix

Or astrolux with their lack of warranty after a month or two

PiercingTheDarkness · 2019-11-14T06:25:14.000Z

Bearbreeder:

Has ANYONE confirmed your 700 lumens measurement?

Quite a few on BLF have the same test equipment sold by Texas Ace and their numbers are very close. Same goes for Matt’s who’s recent equipment tested almost the same.

Bearbreeder · 2019-11-14T06:32:48.000Z

But have they gotten 700 lumens out of the sc31b to confirm your numbers …

PiercingTheDarkness · 2019-11-14T06:39:03.000Z

It doesn’t matter what light they’ve tested, it’s all the same because it’s properly calibrated. If I wasn’t confident in my test numbers it wouldn’t make sense to sell my lights below the stated rating.

You could jump on over to Maukka’s thread and inquire from the one who sells the calibration lights.

Bearbreeder · 2019-11-14T06:43:07.000Z

Ummmm so no one else has confirmed your numbers …

Theres a reason why we dont rely on a single data point

Perhaps you got a sc31b with an unintentional firmware throttle …

Note that the difference matters much in the real world, you can see in the vid above that the sc31b is quite close to the sp31v2

PiercingTheDarkness · 2019-11-14T06:51:24.000Z

Did you miss where I said I sold “them” I have quite a few and I test every light before my customers get it.

The SC31B has a much tighter beam so it throws similar to the SP31 but doesn’t have the same spill

Bearbreeder · 2019-11-14T06:58:39.000Z

I didnt miss the part where no one has confirmed your numbers yet …

Since you have a few, whats the current draw on turbo?

Can you tell the difference?

PiercingTheDarkness · 2019-11-14T07:07:13.000Z

Sorry, I’m not going to continue with this point less conversation.

As above someone else agrees that sharing numbers is beneficial

Bearbreeder · 2019-11-14T07:09:49.000Z

Well share the current draw please

Since thats EXTREMELY important so that if someone wants a protected bat, they get one under the threshold

Oh and the LVP test which is extremely important too

PiercingTheDarkness · 2019-11-14T14:16:08.000Z

Any protected battery will be fine even with 1000 lumens.

You can do that. I posted my result of lumens.

Bearbreeder · 2019-11-14T07:24:38.000Z

Im simply asking for the current draw and LVP test, which you of course measured for your customers (especially to see if there is lvp)

I mean thats more important than the 700-1000 lumens as these affect the actual running of the light

Here is a protected bat based on a pana 3100 mah which trips at ~3 amps

Thats damn near what a “1000 lumens” light would draw
