This site has different flavors of the 219 and other Nichias. They list a 5000K "white". They also list a different Nichia NS9W383 with a 130 degree viewing angle. Might be better for floody lights.
Just an FYI. Might be costly to get them to the US, might be cheaper to get a European member to post them to a US member.
Those 219 are not high CRI, just in case anyone thought that they were.
Ledrise has 5000K 219 for less than $2/piece and shipping for LEDs is free if you spend about $12. Free shipping is slow. You can spend a little more for faster shipping or you can tell them you're a BLF member and try to work something out.
My testing of the ’219s that Illumination supply has been shipping lately shows that they are in the 4000K-4200K range. The only ones that were around 4500K were from earlier batches. I don’t know of anybody that has makes high CRI LEDs in the 4500K and above range.
Texaspyro, how do you test the temp range?
I’m still trying to figure out what I like. I have a decent range now of different temp lights but to tell you the truth, other than the extremes, I don’t think I could tell the difference between my neutral Crees and Nichia without comparison side by side.
Not hi CRI, so if you’re going to buy a 5000K LED might as well get an XP-G2 which will have much better efficiency.
I also have a couple of formulas that calculate the CCT directly from the CIE color coordinates generated from the color sensor readings. They don’t seem to be as accurate at the moment…
The xpg2 4c will give the nichia 219 hi cri a hell of a run for it's money and is much brighter ... some of the best crees I've ever seen and I think the cri is very high on these too the color rendering is very good .

I just recieved this triple for a build and other than its a Nichia
219 i dont have much experience with this LED other than
what i have listened to. Im hoping its the shiz-t and i see or appreciate some of the hype..lol
In the same package is a high CRI XPG2 triple
powered at 2.5 amps per led.....just in case
If anyone cares to decipher feel free.
2.5A per led? Isn't that too much? I thought XPG fade at 2A.
Previous XP-G R5 perhaps not 2.5A The new XPG2 R5 have
been driven north of 2.5A Its well above spec and and
over driven. Im sure there's a few folks on here much more
experienced that can provide exact numbers..
I see I misread. You mentioned "in the same package" and I assumed that it was a regular old XPG triple from Illumination Supply. I didn't think IS sold XPG2 triples or high CRI XPG triples, let alone high CRI XPG2 triples.
Can you link to where you got the high CRI XPG2 triple? Thanks.
Afaik they don't. LEDsupply has some XPG2s in series or you can try reflowing.
Those are not high CRI either. Darkside said that he got
and I was hoping to find out where he had gotten it.
Wanna bet? Loser buys any light the winner chooses,... say
$20.00 max ? I'll try one of them Sipik XM-L zoomies or somthing..
Whats high CRI?
The cree XP-G2 are available in Available in white, outdoor white and 80-CRI white.
Notes:
• Cree maintains a tolerance of ±7% on flux and power measurements, ±0.005 on chromaticity (CCx, CCy)
measurements and ±2 on CRI measurements.
• Typical CRI for Cool White (5000 K - 8300 K CCT) is 70.
• Typical CRI for Neutral White (3700 K - 5300 K CCT) is 75.
• Typical CRI for Outdoor White (4000 K - 5300 K CCT) is 70.
• Typical CRI for Warm White (2600 K - 3700 K CCT) is 80.
• Minimum CRI for 80-CRI White is 80.
The Nichia I had been buying is 92 CRI
CRI is Color Rendering Index. The higher the CRI, the more accurate the color rendition.
EDIT: The 3up XP-G2 mentioned is 70 CRI.
Betting whether or not IS sells triple XPG2 hi-cri boards? Sure I'll make that bet. :D Show me a link.
I said XPG2. ;)
That’s XP-G, not XP-G2.
Edited it.
Still, 80 CRI is about it for Cree leds, yes?, No?
