Updated some of the info on the Nichia 219s. As rojos pointed out not all Nichia 219s are Hi-CRI, only the H1 type. Due to this they are only available in bins up to B10. 

If I can find enough info on the SSC-P7 I will add it.

SSC-P7 added. Sadly, I do not have enough information to add the Z7, I will continue to search for more info but I doubt I will find it.

Epic job Scaru!! Smile Cheers man!
The S2, S3, binned Cree XPG were unavailable when they first appeared because,
FourSevens (4Sevens) bought all the production!!!
i`m sure i read that the Seoul Semiconductor P7 is now discontinued…
………………. SSC Z7

Speak on this?

Sorry for the late reply, I hadn't noticed it. Surprised

They are actually available from my favorite source, Illumination Supply. 

https://illuminationsupply.com/cree-xpg-bare-90-cri-q2-bin-7b-3000k-p-61...

They are rather inefficient, and are 3000k so very yellow. It's all a matter of personal preference.

I actually already said that it was discontinued in the write up. Wink Thanks though.

I think the Luminus Devices LEDs should be in there and maybe the title should have something like Cree & Luminus LED Data sheet thread....   Or something like that,   or not.  Just thinking out loud.

 

Thanks for making the thread. Honestly, I never would have thought of something like this.

The reason I can't add the Z7 is there is no lumen testing on it that I know of. I guess I could use the emitter lumens...

Links to all of the LEDs and their datasheets added. Does anyone have a link to the SSC-P7 datasheet? The one on their website was taken down.

Do you guys think I should add MC-E/SST-50/SST-90?

I have SST-50 and SST-90, and don’t know anything about them. SST-50 neutral.

My LED comparison thread with links.   Scaru - this links to Illumination supply.

 

I think the SST-90 & 50 should be there, since they are still valid leds and still used. Probably the MC-E as well, but less so, since it's about dead.

Oops, I guess I had the wrong thing in my clipboard. Thanks for pointing that out OL. Smile I just added the MC-E and I'll do SST-50 next.

A writeup on the SST-90 would be worthwhile. It’s wicked bright!

2 different data sheets on the SST-90, with graphs, if you need them.

Thanks, I already found them though. But in other news, SST-90 has now been added. Big Smile

Any more suggestions on LEDs to add?

Thanks…pretty helpful.

No one, after lighting a lamp, puts it away in a cellar nor under a basket, but on the lampstand, so that those who enter may see the light.

Killer info, Scaru. But I would put an addendum on the SST-50 entry. I have watched my chief of police buddy in Virginia show off his, and without a doubt, most of his 800 lumen+ SST-50s died — all except one. Selfbuilt (I think) reviewed the M31 Triton and called it the brightest SST-50 made. I have searched far and wide and what I found seems to confirm what our own 2100 said about this emitter: that on paper it does well, but not in real life. I have yet to see one of these really excel, and doing so would require a chunk of an engine block for heatsinking and active cooling like in the Microfire Pioneer II version…

I guess it is little wonder why Olight opted for the SR51 (a U2 XM-L) over SR50, knowing this.

To get a high-CRI LED generally requires an increase the the red part of the spectrum. Rather than tweak the phosphor mix to get the red boost by converting more blue light to red, most makers seem to be adding a material to the phosphor layer that filters out part the non-red part of the light. That is why high-CRI LEDs are not as efficient as normal ones.

Is wikipedia wrong then? 

" If several phosphor layers of distinct colors are applied, the emitted spectrum is broadened, effectively raising the color rendering index (CRI) value of a given LED."

Or does that simply mean that is one way of doing it?
