I bought several Cree XR-E Q3 5A for home lighting projects.
Nice color, but still a bit too cool white for me.
What should I get? Will 6X be sufficient an increase towards warm white?
What about the natural white Seoul P4? Its 93 CRI looks attractive, but it is only 60 lm.

Any suggestion for a source for MCPCB mounted warm white Cree XR-E in continental US?
I know that ledlightingsupply has some, but this time I won't be able to reach their USD 100 minimum order quantity.
 
5A is warmer then sunlight and even my "warm white" flourescent lamps.....are you sure you need warmer? perhaps what youre looking for is more yellow in the spectrum? because 5A has alot of red?

I have Q2 5A from ledlightingsupply, and Q3 5A from dereelight, and both look very cool compared to my CFL and incan.

@ Sgt LED: I haven't tried 5B, but they have the same CCT as 5A so I don't expect a big difference.
 
If you want warmer, try 6A or 7A. I have a 7A and use it in a mule for 100% flood. It is very warm and easy on your eyes. It has a strong yellow/brown tint though.
 
There was a press release last week from CREE about further subdividing their warm/neutral bins that follow ANSI C78.377-2008, with each bin being something like 75% smaller than current offering, and 90% smaller than ANSI to allow for precise color matching.

I have not seen mention though of the new labeling, has it been posted?
 
I haven't seen or heard anything about this bin split. Can anybody who knows something start a new thread with a link or something?

EDIT: New thread about it here.

Cutter now carries some Q4 5C XR-E.
How does 5C compare with 5A?
Marginally warmer of course, but is it as good Re. color rendering?

Color rendering relies solely on CRI scale, not in color temperature (kelvin degrees). Warmer tint does not equal high CRI, only lower temperature. A piece of crap blue-tinted emitter painted in yellow, is still a low CRI piece of crap in a different color.

All Cree Cool and Neutral white series has 75CRI, warm series has 80CRI nothing better for Cree. Add some amber, red or green leds to catch your likes.

I find that the 5C looks more like sunlight than the 5A. I haven't noticed any real difference in color rendering between the two. On a white wall, I prefer the 5C, but in practical use, it doesn't seem to make a difference.

yeah i notice 5A is more red than yellow, anyone can post picture comparing several cree warm bin such as 5A, 5B, 6A, 7B etc?

thanks.
 
EngrPaul had a bunch of differnt emitters in Fenix E1s for sale a while back, it seems like he has withdrawn the sale as well as removed the info, perhaps you can pm him?

I'm sensing some angst here. Is there anything you want to talk about?:D
