Nichia 219 on Cree XP-G star

FYI, I didn't realize I could put Nichia 219's on a Cree star. I'm probably the last one to knowEmbarassed, but just in case someone else doesn't know, here's a photo.

I've been using the Nichias on those 10mm stars, but I wanted to use them in a P60 drop-in and I got a couple 16mm XP-G stars. They work fine.

That looks good.

You've really taken a liking to those nichia leds haven't you. But then from the spec sheet data they are nice!

the CRI difference is that great, that you can actually notice the difference lol!

But seriously, you get CRI but also get to eat the tint cake too (not too warm)

Where do you buy blank xpg stars? Why not just use the 10mm stars? Are they too thick? I’m thinking of doing a nichia 219 build myself.

Here. The reason is a P60 drop in will hold a 16mm star perfectly so that the LED is centered. The same cannot be done with a 10mm star. However, it would still work but chances are you LED would not be centered.

How does the color of these LED’s in real world usage compare with say a neutral 3C xml? Moving from cool white to neutral I saw a hugee difference that made me never want to go back to cool whites again. Is the difference between the cree neutrals and this LED as great? I’ve been wanting to try these for a while.

where do u get raw led’s and how did u center it?

I have NICHIA 119. it has no dedicated thermal pad like 219. didn’t even found MCPCB for it.

Not sure if this helps but there was a discussion of it here.

Thanks scaru :bigsmile:

never saw it before

When the solder paste melts, the surface tension will pull the LED into place.

They carry a lot of different MCPCB’s. I believe they’re located in France.

Nichia 219 (4500K 92CRI):

Cree XP-G R4 (4200K 75CRI, tint of this LED is almost identical to the 219):

Cree XM-L U2 (?K 65CRI):

Cree XM-L T5 (5000K 75CRI 3C?):

Cree XM-L T5 5A (4200K (supposedly) 75CRI):

Midday Sunlight (~5777K 100CRI):

Sorry about the blurriness in some of the pictures, I was trying my best to keep the camera steady without having to go get my tripod out of the closet. I hope you can see why everyone is nutty over the 219. White balance on my camera was set to “sunlight” (not sure what Nikon classifies as sunlight, but you get the idea). The bottle is a gold/brown color that many LEDs wash out to a green or yellow color. The top is beige brown and the only LED, IMHO, that makes it look correct is the 219.

KLowD9x,

Wow thanks so much for the pics!! They really told me what I needed to know. The 3C actually looks pretty good compared with others, though there’s just something about the Nichia that looks so much more natural if you do a direct A/B comparison. It looks like I have to start saving for another mod…

Nichia does a good job with colors but I would prefer a bit more higher Kelvin temp.
Too bad, it is not possible yet.

I have just one nichia dropin and I drive it modestly at around 1A or a bit less.

Not sure why OL didn’t link his other excellent thread.

Modesty perhaps?

Perhaph I haven't been watching the threads, LOL. Too busy in the shop, but others usually have the answers, so I don't worry too much. Nice to be looked after.

KLowD9x Thanks for those photos!! Absolutley what we needed. You should make a thread on those. Gives no doubt as to why high CRI beats any low CRI "tint".

If I make a thread on this, I will be sure to set up a tripod and be a little more similar in my pictures and less blurry. If there are more requests for this, I will get out the tripod and the white towel and make it happen. I’m glad you all found the pictures helpful. The surprising thing to me is even though the 129 and XP-G R4 neutral are almost identical in tint, they render colors in a completely different way. Which is very obvious in the pictures.

that would be very nice to do, nice pics
