Luminus SST-40, a N4 BA bin tested

[mattlward]

From what I have read, there is almost no tint shift. I may try one that way in a C8, just for giggles.

I picked up a pair of these in 6500k from KD. Not sure why I did it, really hate anything below 5000k. Mounted one up and tested it, very bright but just can’t handle the tint. So, now they will sit for an eternity in my LED box. Maybe someday someone will ask for a mod with that tint… Would love to see these in 5000k - 4000k.

Dedome?

Why not just dedome them?

Doh!

Just do it!

Got just shy of 160kcd in one of my C8s.

Just got my hands on some P2/ AA binned( kit 752)(VL voltage binned) emitters from those.

In a M2x host, they start at 8.5 amps with a VTC5 battery and they hold! over 2k lumens and the incledible 370k candlas folks with the lovely pinky 5500k tint( inder M2X default glass)
A default M2X compared to this looks like a joke, literaly

I just received five SST-40 from this seller on Aliexpress, they turned out to be the real deal. There is of course no specific information about tint/bin but with my unscientific testing they seem on par with the one I bought from KD.

There is also a bit of green in the lower modes just like the one from KD. The MCPCB’s is not very good but that didn’t come as a surprise. The price has gone up a bit I payed $1.69 a piece.

Price is going up folks, $1.69 when I ordered first time and now they are $2.09.

[Mitko]

2$……Arrow ones i payed 5.78 euros each , before VAT

Yet they aitn greenish at all, (when dded), more or less something like 2A bin( not realy but close)

I havent tested non dedomed version so far :)(

Anyone else order from the other not so great aliexpress seller? They are still selling at $1.60pcs but I’m worried I’ll get fakes.

[Newlumen]

Most people order sst40 from the kaidomain.

[mattlward]

The KD are real, unfortunately they are also 6500K. But, I had to try a couple.

[Pok]

My KD last ordered 10pcs, fail to dedome in gasoline and toluene.
Bond wire came off and stick into perfect dome.

I reflowed 3 pcs (from ali seller) yesterday, dedoming them later today…

Can’t answer thas queston, but maybe this is an answer to you next question:

I myself bought LED’s from Ali seller Shenzhen Great Technology Co. Ltd, but on the star was written:
on the + side: CREE
on the - side: OT-LED

[Mitko]

Those are the same stores BLF fellas, i know OT LED rom the time when they started, at first ( the store owner is called Amanda) they provided me even with the exact bin, but then they business expanded and they started selling fakes, factory reject and bad binned emitters, youll never find anything good in there now

Typical corporate illness, callled more profit and greed: thats the main reasos we have those random global econ crysis if you ask me, too much greed

You know, there was a time when this store have found 1304 Cree chips with the impossible bin and 96 CRI, and they were great….now, they care only for more profit, not the quality

99% of the buyers dont care the the emitters bin and quality as long as it “shines”

Sellers like RMM and IOS are rare as hell, Mouser for instance dont know exacly that they are selling, i had several quite long chats with their support, and believe or not i do believe that most of BLFers will work ways better than those ppl

Can’t find them either.
Maybe Mitko bought them all.
Or he was joking?

@Mitko

I got some from Arrow too: 7500k the highest bin,

The main difference is: when properly dedomed( its not that easy though, at least those samples) The tint didnt shifed much, like only 1000k or something , thus resulting in the best cool white tint( accoarding to the BLFers), like 6000k 1D or so, paired with an the AR glass even i like it.

I tried keeping it at about 7, 7.5 amps tops, to awoid burn-outs

Paied with a good fed dd driver it resulted at arround 2050-2080 lumens( at 7 amps) WHEN DEDOMED, measured with my spectrometer, candelas ( in most knows hosts) are as follows
C8 - 162000
X6 - 108000
L2 - 315000
B158 - 269000

I`ve modded a M3x torch with it too, using a boosted default driver at 7.1amps and it ended at 335k candelas

A very good emitter, especialy if you aint at a good cool white tint after dedoming, simmilar or even an idea better than W2-W3

Thanks for this. Wait, so does a dedomed sst40 throw very similar to a dedomed xpg2? I would t think it would, but looking at your numbers on those host,especially the c8, it seems like a xpg2 would give similar results. I think I remember seeing you get like 175 kcd on a c8.
