I am planning on build myself a light stick. If you don’t know what a light stick is well then it is a stick that makes light. Hehe. I want to use it for photography and it needs to be about 500mm long. I plan to pack it with leds and 18650s.
My question is, what is the highest CRI LED that is +5000k on the market?
I was planing on using the CREE MTG2 PO but it is only 75 CRI. Ideally I am looking for a +90 CRI that is 5500k.
Any suggestions?
Nichia NVSL219B R85 (90 CRI) 5015k from cutter.com.au is the highest color temperature you are going to find in 90 CRI. Those Nichias are normally binned as 4500k but cutter tested their batch & it came out as 5015k so you won’t find it anywhere else. Cutter search: 219b
Its difficult to make high CRI in high color temperature.
Sorry to hijack this thread, is there any site which from i can order MT G2, 4.500K but 100% sure that its not 4.000 or 5000K, but 4.500K? thanks.
Cree does not provide a 4500K order code in the datasheet. Take a look at Page 3. Mouser does not list that temperature in their MT-G2 search results. I doubt that it currently exists.
Mouser, Digikey, and Cutter are generally your best bet for a wide selection of Cree products that are guaranteed to be exactly what they say they are.
Thank you.
So MT G2 can be bought only on general specs ~5000K or less?
I do not understand the yellow highlighted portion of your post. What do you mean "only on general specs"?
2700k, 3000k, 3500k, 4000k, 5000k.
2700 and 3000 available in 90 cri. 4000 and 5000 available in 80 cri.
Helios-, you cannot link directly to the datasheet. Hot-linking the datasheet results in an error. That's why I linked to the page where you download the datasheet..
Actually you can but the simple post editor will not handle links with spaces. Corrected the link. Spaces are ok using the advanced post editor or just using html code. < a href=“link”>link text< /a>
Ah, thanks. I should have realized, I have to handle links to the reviews and articles on HKJ’s website the same way.
Thanks. It seems that Nichia is the way to go. If I order from kaidoman what is the odds I will get what I am ordering?
Zero. You’ll get a Nichia LED with the appropriate physical shape, but why on earth would they tell the truth about bin & etc? Just purchase the cheapest and sell it as whatever they want.
Is Cutter not a good option for you? Helios- already explained that Cutter has the highest temp 219b’s available.
Have you had a bad personal experience with the Nichias from Kaidomain?
A few members have bought Nichia 219B from KD and they seemed happy with what they got.
No, I have not personally had a bad experience with emitters from KD. As a matter of fact, the one time I ordered an emitter (several years ago) I believe I got exactly what I ordered. That said, I ordered a bottom-bin SSC P7 with a horrible color cast - why wouldn’t they deliver exactly what I ordered 
I am willing to purchase from KD, but I do not trust KD.
Cast around and see what others say. I realize that in SA you don’t have ready access to vendors like Digikey and Mouser at the same price we do in the USA, but to me it’s 100% worth the extra to know what I’m getting.
The only Chinese vendor who I’d purchase from is intl-outdoor.com. Hank has a good track record for delivering the specified tint and bin.
KD sold me the C1 bin, I’m afraid…
No ‘creamy goodness’ as someone put it…
That was a $14.— lesson… 
LXZ2-5790,new led from philips 5700K and minimum CRI of 90,250lm@1A undomed,pretty impressive,but as always,good luck finding them in small quantity.
That one would make a great flashlight! But Mouser does not have the led yet, and Rollinstone157 is still undecided on if he should sell rare Sinkpads, like LuxeonES-Sinkpads...the build stays on the waiting list for a while :-(
I, for one, do not trust KD as a source for LEDs. I ordered a few XML2s in a 5B tint. What I got are much warmer, probably in the 7C area. |(
From now on it will be RMM or IO for me.
Yea. you share my feeling about KD. Cutters just is very very expensive to SA. We have to DHL them due to the post office having sticky fingers.
