SFN55.2, SFQ55, SFN60, SFQ60, SFS80 and LED info

I'm seeing these new LED pop up in a few lights but there doesn't seem to be much information about them yet. Apparently they're made in China but I don't know any more than that. I haven't got my hands on any yet.

This is what I've found out with a bit of Googling.

 

LED Footprint Approx Lumens
SFN55.2 7070 7800 lm
SFN60 7070 8000 lm
SFQ55 5050 3000 lm
SFQ60 5050 3000 lm
SFS80 3535 1850 lm

N=7070, Q=5050, S=3535

SFN55.2 LED


(Photo from Nealsgadgets)


SFN55.2 LED specs

  • 7800 lm (according to Nightwatch)
  • Candela is about 70% of the SBT90.2 (based on NI03)
  • Voltage: about 3V
  • CCT: "cool white"
  • Footprint: 7070

Appears to be somewhere between an SBT90.2 and XHP70.2 LED.


Flashlights with the SFN55.2

 

SFQ55 LED

I can't find much info about this one, other than this Shopee page.

(photo from Shopee)

SFQ55 LED specs

  • CCT: 5000K
  • Lumens: 3000
  • Footprint: 5050?

Flashlights with the SFQ55

 

SFS80 LED

(photo from Kaidomain)

Kaidomain have a MCPCB with the SFS80 and also call it "P35 HI"

 

SFS80 LED specs:

  • About 1850lm
  • Footprint: 3535
  • Voltage: 3V
  • White 6500K / Neutral White 4000K CRI80 (from Kaidomain)

 Seems to be most like an XHP35

Flashlights with the SFS80:


SFQ60 LED

 

SFQ60 LED specs

  • About 3000 lm
  • Footprint: 5050

Some info on this TLF post

  • Footprint: 7070
  • Lumens: 8000

Thank you for the summary, Dave. I have already asked my contacts at Sofirn to find the datasheets for these LEDs. They are highly interested at least in testing SFN55.2. If anyone can help me finding out more about the manufacturer and the corresponding datasheets it would be great.

My first reaction would be to disregard these, they are made by a company we are not really familiar with, there is not much data out there about them and we do not know what production quality is like. But… I would have said the same about the GT-FC40 and it is a fantastic LED. So, maybe we will find out more. The 3535 does not look like it will throw like the XP-L Hi as it appears to me to have a larger square emitting surface. But, I am sure they will be found and tested here.

BTW, nice sleuthing!

Thanks LP. I’ve been though pages on Google but haven’t found any datasheets at all.

Nightwatch seem to have their hands on them, though I don’t know much about Nightwatch either. Perhaps Neal has some contacts that know more.

Mine too! They look like the kind of LEDs you get on a “999,9999 lumens” “XHP90” flashlight.

But I had a Nightwatch and it was impressive quality for the price, so I expect they know what they’re doing.

Hopefully someone with a bench PSU and sphere will be able to test some.

I’m looking forward to seeing data on these start trickling in. Do we know what voltage the SFN60 runs at, and whether or not it has a dome? If it’s a flat 6-12V emitter I could see it catching on in single-LED throwers as an option that’s (potentially) cheaper than an SBT90.2 but more intense than an XHP70.2, which I’d imagine lots of people (including myself) would buy.

Maybe someone with contacts to Mateminco (Freeme?) could ask for datasheets. I know Lexel once used to be in close contact with Mateminco but he has been offline for 9 months now. I try to ask helicoil (Martin) on TLF for he is very active on the Chinese flashlight forum Baidu and frequently posts news about these new emitters. Sofirn said these LEDs were maybe customized for certain manufacturers. That could leave room to hope for warmer tints (4000K - 5700K) if specifically requested. Usually, these LEDs come in 6500-7000K coldwhite tint. If I am not mistaken Simon Mao is in close contact to Getian who are willing to offer any desired CCT on request, e.g. for the FC40 LED.

Getian is hesitant about different voltage configurations though over cost concerns with complex bond wire layouts.

I’m particularly interested in 5050 footprint emitters in 3V and 4500-5500K ~80CRI (Rg > 98 , R9 > 5 , Duv < 0) for high output. A Getian competing HiCRI variant would be nice as well.

I would really love to see a 6V version of the FC40 as an upgrade path for MTG-02 lights.

As far as I have seen, those new China-LEDs are two steps back in terms of efficiency.
Sub 100Lm/W in times where even High Power LEDs are usually over 150Lm/W is not the right way

In this page shows the Nightwatch NSX3E "Extreme edition":

https://item.taobao.com/item.htm?spm=a1z10.3-c-s.w4002-17110364424.12.c9...


 

The description (in Chinese), translated, gives these info

NS33FE: 3x SFS80 6500k LED, max 24A current, 6200 lumens, 60kcd (490m)
NS34Mini: 4x SFS80 6500k LED , max 24A current, 6800 lumens, 70kcd (529m)

How do you know that? Have you tested it? I understand why the SFN55.2 might not be efficient with it’s very low vf. Combine that with a linear driver and yh it’s not gonna be great. At turbo it seems pretty similar to 7x osram 2mm. Pulls about the same current with similar output.

That’s at close to max output. I don’t think a dedomed XHP70.2 will be much different.

I tested the SFN55.2 in a NI03 and got near makes no difference 29 amps at probably 3.3-3.5 volts (6912 conservative Lumens) with the included 26800 battery. I’m thinking of trying a 30T to see if I can get more since I know that 26800 is really working hard at that drive current. Until someone officially tests one in a sphere to prove it, I’ll put my money on the table that the SFN55.2 will be as bright (or brighter) than a 70.2 with less power consumption. Take off the dome and it will be even less output.

Nice legwork Dave! I am excited to see more of these high power Chinese emitters in flashlights. Hopefully we can get some data sheets soon.

You called ?

 

Night Watch LED reference chart 2021 first edition ...... Thumbs Up

 

LED reference chart ( most but not all special "Eastern" editions )

 

Columns from left to right


LED - size - luminous area - bead voltage - cont.rated current - max.safe current - cont.luminous flux - max.luminous flux - luminous flux density - retail price


Last column = remarks ....

 

If you are looking for examples of lights using some of these new LED's check out the TLF.

( that said ... a number of lights allready mentioned on the TLF ... have not yet " arrived " at the BLF ... )

 

This information was provided to you by way of the Baidu Community ... with special thanks to Night Watch ( aka Night Patrol ) ... 

 

Cheers,

 

Martin ( ... just a messenger ...   )

I would also be reticent regarding LED lifespan… until this is verified by a trusted 3rd party.

For some reason, the luminous area values in that chart seem to be way off for at least some of the emitters.
SFT70 = 7 mm²
XHP35HI = 5.9 mm²
SFS80 = 5.3 mm²

Interestingly, the lm/mm² values seem mostly in line with values in my tables. Two wrongs make a right?

Thanks! This is great.

From the image, these ones are discontinued or will be soon:

  • SFS80
  • SFQ60
  • SFN60
  • SFQ75

The chart also has some 11mm * 11mm LEDs, like the SBT90.2 but more floody:

  • SFH55 14200 lm!
  • SFH43P 8900 lm
  • SFH40 8000 lm

We need to find a cell that can handle 62A for the SFH55

Im really torn on buying this new FT03 (mateminco version) with the SFN55.2

 

Can anyone who has a light with one of these LED's share any information? is it interesting / WOWing / fun? I have all three LED variations of the FT03 (one with SFT40 not sst40), any reason i should even be considering the SFN55.2 version? 

 

If so, better to run a Molicel P42a or one of the QB26800 batteries i have laying around? I would need to buy another battery tube though, thats another $10.. thats $60 for an FT03 that does (7000?) lumens. Is that compelling? I don't know.

Well, if the NI03 is any indication of performance to the ft03, I say get it. You won’t be sorry. I don’t think the heat sinking is as good though on the ft03 so your duty cycle on higher modes will be lower. Use the 26800. I really like that cell and it’s probably diminishing returns to use a P42A.

That’d do it!

Other option is LiPo cells, which can often discharge at 100C. With a 5Ah cell that’s 500A!

LiPo has some major cons over LiIon but I don’t see why there aren’t hotrods that use them.

My NI03 Valkyrie with SFN55.2 has arrived in the US.

Tempted by the ft03, but they didn’t offer 26800, and I love nightwatch fins/knurling.

As long as their aren’t weird colors to the beam, I think I’ll like it a lot. I don’t have an SBT90.2 to compare to…

You will like it. Good beam also. 100 times better than xhp50/70.2 and throws great.

Pretty excited. Wish it would show up before this weekends trip.

I hope to use it boating. I have tried so many lights for the range inside an aspheric thrower. We will see. I will try to get pictures, probably October though.

Kaidomains Custom P35 SFS80 4000K version can’t take the 8 amps that they tell it should. I fried one, reflowed the second one with more care and it also fried at 8A.
