Quick Guide to Popular LEDS - UPDATED FOR 2024

Only I now realize it, but you forgot to add the 3v version of the XHP50.2

Might be a good idea to specify XHP70.2 as well, instead of 70.x, as I haven’t seen any flashlights using XHP70.3 HD yet, other than mods.

“Sophia” 5mm led were Chinese made High CRI Yuji alternatives that were used briefly in a new batch of Sofirn C01 lights and I believe they are the same ones as sold by rngwn. Yuji and Sophia led are both discontinued AFAIK.

LUXEON V2 and LUXEON V were regarded to have decent even tints in contrast to the egg yolk cree rainbow.

The decent-tint only applies to the 4040 Luxeon V. The V2 sounds like an upgrade but is an unrelated 3535 emitter.

I’ve had the V2 in 3 different CCTs, and they were quite tint-shifty, about what’s typical for a low-CRI domed emitter. It’s got more tint shift, lower output, and lower CRI compared to a 75CRI first-gen XPL-HI, so nowadays there is no reason to use it at all. Heard from at least one other modder about how much more tint-shifty it is compared to the V.

May not be news to others, but I just found it: a summary of various LEDs on Reddit by @alumenum:

Nice find!

For the new folks here, I will note that this list is from Feb 2022, before some of the currently most popular emitters (519A, SFT40 95CRI, XHP 3rd gen HI, etc.) entered the game.

That thread is linked at the end of the original post as well. It is very insightful

Available from KD in 5700K : http://kaidomain.com/219C-V2-5_58W-1800mA-800-Lumens-SMD-3535-LED

Very interesting, 5700k isn’t my favorite, but I am glad there is finally an R9050 variant marked in the datasheet and is actually available.

If it becomes available in 4000-4500k R9050 I might buy some, to put into a DM11.

The Niwalker N01S will arrive at my house in a very short time. And I would like to know if someone can tell me what LED it has. I put the best photo I have found of the LED. If it helps, when it arrives I will post better photos.

What’s the approximate footprint? Looks like one of those custom round-die SFT40’s, or its larger 7070 variant by LMP.

I don’t know what footprint it has, I don’t have the flashlight yet. But by the size of the flashlight head (5.7cms), the lumens (1800/2000lm) and the estimated range (1100 meters), I think it should be the size of an SFT40. I don’t know why not all brands indicate which LED they use exactly.

According to ZeroAir it’s Osram NM1

You are wrong. The flashlight you are talking about is the N01, I am talking about the N01S.

Looks like 5050 so probably a P50 HI or one of those clones.

“Chinese round die emitter”, it’s essentially a placeholder and does not mean much, because most of the information about these Chinese round die emitter is opaque.

2 Thanks

I asked them about it, and they only gave vague words “New high-performance emitter”. And as said, there is no actual name for these emitters.

1 Thank

They are probably made by San’an or some other OEM. San’an is one of the biggest LED producers in China (owns Luminus), so I’d deduce a lot of these mysterious LEDs like SFP, SFQ, SFH, P50, P70 etc. are produced by them for others without labels (or publicly available datasheets). The binning for these is pretty erratic also and you might get lucky and get a good one or not so much and get a green, and/or lower performing one.

1 Thank

The Niwalker N01S arrived today. It’s gorgeous, incredibly beautiful the finish it has, it looks like ceramic, it’s incredible, I love it. As for the LED, I would say that it is somewhat smaller than the SFT40. According to my Opple Light master 3, it has 5500K, 65 CRI, and emits around twice as many luxes as a Convoy M21E, measuring both at about 4.5 meters away from the lux meter, at that distance I took the following records:

Natfire SF2 (LEP): 30,000 lux
Astrolux MF02 (XHP35 HI) : 27,000 lux
Fireflies T9R (Osram W1) : 25,000 lux
Niwalker N01S: 19,000 lux
Haikelite MT41 (Osram PM1) : 11,000 lux
Convoy M21E (SFT40 6500K): 8,700 lux

I think the performance it has is really good, I am delighted with the purchase and highly recommend it.

Actually SanAn never made emitters, LatticePower also, they only made dies/chips. Emitter manuf such as Luminus, ChangDa (manuf of SFQ, SFY, etc) made emitters.

LatticePower may make and sell both chips and emitters.

Most good Chinese emitters can be assumed to have chips from either brand, but different emitter manuf end up making very different products.

1 Thank

This would explain the different but similar round die I found in SFT-25R and W5050SQ3.

So according to your information Luminus seems to be the emitter manufacturing department of Sanan. (Luminus belongs 100 % to Sanan)

What surprises me is that LatticePower seems to list a wide variety of emitters on its own website. If they don’t manufacture them themselves (only the chips), who makes the LEDs for LatticePower?

O I get it right, ChangDa manufactures other LEDs like SFH73, SFN55.2 and so on? Can you confirm that the Luminus LEDs like SFT-40 or SST-25 are actually made by Luminus themselves or are they made by ChangDa and just relabeled for Luminus?

Do you have any sources to back up this information? Then I can adapt my tests and change them slightly if necessary.
