I am looking into an Emisar that uses Nichia 519a LEDs, but I do not see any specs listed on Hank’s website regarding the CRI. Is it 90? 95? 98?
Also, does using a dedomed LED change the CRI?
Does the CRI remain consistent regardless of the color temperature?
Re Emisar lights. If the info is not listed try emailing them Hank has always responded to me.
De-doming warms up the CCT.
Welcome to the rabbit hole, thunderstruck 
I just bought an Emissar D2 w Dedomed 519a 4500K. I am very happy with it, my primary use for this CCT is in the evening. According to my Opple 3 the CRI Ra is 97. Take that with a grain of salt… imo anything over 90 is good.
I am very happy with the LED. I mainly prefer Dedomed 519a after sunset, and Domed during daylight… after numerous comparison purchases… here are some of the domed and dedomed ones Ive tried:
the 3400K, third from the right is my most used CCT atm. It is a dedomed 519a 4500K
for daytime use and also for a workshop light, I like domed 5700K (it is the only 519a CCT I leave the dome on, and specifically for use as a work light)_,
for evening use I like the dedomed 4500K which becomes about 3400K as in the photo… it is a more relaxing color and has less blue light than the 5700K, so it helps get me ready for sleep.
you have to buy and try for yourself, to learn which CCT’s you enjoy, for the settings you use your lights
I dont know and I dont know, but honestly, I dont think it matters… The 519a is a great LED, and any variations are not going to change my mind about that
suggest you buy a light with an LED you want… Use it as an introduction, to determine what you want to try next after that
welcome to the slippery slope…
What is your intended use for the light? Mostly daytime work related, or mostly after dark, after work… or?
IIRC, it varies based on bin and CCT as well as just luck of individual LEDs, but generally 95-98, with 50+ R9, and dedomed 519A usually have marginally lower CRI due to too much red, but overall still high.
Yeah, I’ve read that dedoming tends to push things into rosy-light territory – but some folks like our own @jon_slider clearly prefer it. Me, I’m pretty happy with the warm no-name fully-domed 4000K LED that came with my TS10 for my indoor use cases – outdoors the 6000K SFT40 in my FC13 works best for me.
Different strokes for different folks and all that, I guess…
All of your questions will be answered by the test of the 519A (519-V1) which is planned for the next two weeks. 
My favorite 519a is the 2700k. Dedome that bad boy and you have a beautiful 2200k rosy sunset orange light. Just beautiful.
Perfect for walking around inside at night.
I actually really like this LED and I’m not picky about cct or cri. The tint is great even into CW cct and the output is also very good. It’s not as good as the LH351D 5000K Ra 90 though, but the 519 doesn’t have the bad -duv the Samsung does at low-mid drive current. I have a TS25, and now testing a E75 with the 5000k version. Dedoming lowers the cct and the output, but increases intensity (lux).
Looking forward to what you find!
Thanks everyone for the responses so far. I learned a lot.
I love 2700k since it is close to the old school incandescent color temperature, so that’s what I’m going for with the 519a.
I recently put a 519a 2700K into a light, you may enjoy the photo and info:
I also dedomed it:
the tint moves it below the bbl, making it more orange than yellow
as you can see it makes it a lot warmer too
enjoy whatever you enjoy, lol
