Andúril 2 coming to Sofirn - The general Sofirn development thread

not sure i understand why u want 2 cool white and 2 ww leds??

Tint mixing, and superb dynamic range with 90CRI LEDs.

It’s what the BLF lantern does.

I’m guessing they will install a driver that can control the 2 different tints separately (maybe it comes with such a driver stock?). That way you can adjust color temp on the fly.

Sofirn mentioned a new revision of their Sofirn C8G in the Aliexpress shop with a moon mode an a new Standby Mode.

Does anyone know what die new Standby Mode means? Maybe they removed the annoying instant on when clicking the tail switch? :+1:

I asked them on ali but get no answer…

Usually standby mode means you can turn off the light by the side switch. The tail switch continues to keep the power connected.

I think so, looks like another C8G will be incoming… :smiley:

I will use the first revision as an Host, waiting for drivers from Lexel.

Any news on an updated/upgraded Sofirn SP33?

Since late August there’s ‘rumours’ about a new version with a lower moonlight, a different emitter (XHP50B-3V?) to get to 3500 lm and a type C charge port.

As they come in a 6000K tint now, I hope Sofirn will offer more neutral and/or warmer options. I could need a 4000 - 4500K version.

Ditching the boost driver on the SP33 will be a definite downgrade IMO.

How? Doesn’t a boost driver require more from a battery, reducing runtime?

I’d rather not have a boost driver as I’m not a fan of losing modes due to voltage

I wish Sofirn would design a long range light that’s mountable to a gun like Maxtoch’s X2

As a dealer Maxtoch refuses to allow me making purchases directly due to there being a local distributor.

Nope, overall runtime is the same and potentially higher. The benefits are a set output which gives consistent brightness, moderate heat and increased runtime when compared to a FET driver due to the set output. FET’s can pull more amps which drain the battery faster and create more heat. So if you want the highest output, use a FET driver. If you want longer runtime at a level below the max, a boost driver is better. It depends on your application.

PS, when your battery voltage gets low, charge it or swap a fresh cell in. Then you won’t loose any modes.

I also heard that Sofirn wants to work on an update of the SP33 but so far I don't know about any details.

I agree with BurningPlayd0h that using FET over a 6V boost driver would be quite a downgrade. IMHO, there's not much of a benefit in using a 3V XHP50.2 instead of the 6V version. All you might get is a bit more lumens in the beginning, causing the host to heat up way earlier as currents will be far above 5A compared to the 6V boost driven version. In return you get a much uglier beam pattern (greenish tint shift with coldwhite CCT only) and no regulation at all, i.e. brightness will diminish as the battery voltage drops.

I admit that "losing" modes feels a bit odd when used to FET-driven lights but this is how Sofirn designed the UI/stepdown regulation. In terms of improving the driver they might be able to finetune its stepdown voltage thresholds a bit less conservative, leaving more room for high-current cells to maintain a reasonable brightness level.

TL;DR...my suggestions for an update of the SP33 would be:

  • improved assembly QC (some SP33 show hazy/milky coating on the inner side of the lens)
  • USB-C instead microUSB charging port
  • improved boost driver voltage thresholds for longer runtimes on Turbo/High modes
  • improved tactile feeling of side switch (less cushy)
  • omission of timed stepdown and usage of thermal regulation with at least 55°C as threshold
  • additional ramping mode (e.g. click 5x to toggle ramping mode / stepped mode)
  • optional: Cree MT-G2 6V LED for a nice floody 2,000lm beam without artifacts
  • optional: more tint options on Cree XHP50.2 (e.g. 4.000K/5.000K, 70CRI/90CRI
  • optional: configurable thermal regulation (e.g. click 10x to enter config-mode) to set user defined thermal thresholds (50°C - 70°C)

+1. Not familiar with the madtorch but I’m looking for an alternative to my M61/surefire combo. Great indoor setup but not enough reach outdoors.

@Barry0892: Any news about SC31A?
Is there a plan to add moonlight mode, preferably <3 lm :wink: ?
If so, will this moonlight mode be available from off (i.e. long press) ?

I highly doubt it as long press from off activates LED in switch

Pretty sure the only people who call a 3 lumen low a moonlight.> are vendors who have no idea what a moonlight mode actually is .

Safe to say a moonlight runs between 1 and 1/4 lumen .
Firefly is below that

Low starts at about 3 lumens and goes up to 30? ?? Depends on the size of the light .
The real reason for the confusion is moons are hard to do well and manufacturers just cheat and call lows > moon modes to sell lights.

Depends on how concentrated the hotspot is. 10lm from a full-flood zoomie has so low lux that it might as well be moonlight. Only difference is that it (eg, my Cometa) lights up a way wider area than a regular light with concentrated hotspot. 1lm from a C8 or GTmini would be painfully bright.

My E03 with heavily-diffused film in front also spreads out the light over a wide area, so even its “low” is quite low. Of course, starting on medium kinda kills night-vision anyway, but…

I would agree that “moonlight” mode shouldn’t be defined by the lumens, but by the candela.

I disagree, when I’m using moonlight its almost exclusively to light up things that are close to me (sometimes right in front of my face) so even a very floody beam will be fairly concentrated at that range.

This might be the wrong topic im posting in here, but the Sofirn C01 used to come with a nice 3200k Yuji LED, now the C01S comes with a 4000k SST-20 which i dont doubt is also very nice.
The thing is im only really interested in a 3000k (or close) AAA high cri flashlight, does anyone make those nowadays?
Or is there a place where i can still buy the C01 with the yuji warm white.
Are there any plans for a new sofirn AAA flashlight, maybe even a 2700k one?
id love to add a AAA to my collection but i have a hard time justifying it seeing as i already have other 4000k lights and i would love a really warm white compact flashlight.
Maybe there is a place i could buy an incandescent flashlight from china somewhere? i own a few incandescent lights and i adore them but there are all simply too large to carry for the little light they give off.
Im sure you could fit an E10 incandescent bulb into a AAA form factor light, i might even try to make my own. but i dont know of any AAA flashlight host that would allow that.
