Nichia 219B vs 219C

It seems there is a >=90 CRI version of the 219C now, how does it compare with the 219B?

Maybe greater efficiency at a slight loss of prettiness? Would love to see some photography comparing both if anyone has any.

I just got a 3×219B S2+ built by @merlot and the difference between that and my Fenix is incredible.

the 219c is not pink (tint is above bbl), as the 219b 4500k (tint below bbl)

maukka has extensive tests of 219c and 219b in the thread this photo links to:
.

fwiw, the 219c is a 9050 LED, the 219b are available in 9080.. the 80 is the red portion (R9 CRI)

personally, I remove 219c leds and replace them with 219b

How significant is the efficiency difference between the B and C?

The efficiency is not all that different, its more that the 219c can be overdriven to around 1500 lumens whereas the 219b tops out at around 700. The tint and cri of the 219b are lovely though

the 219c is about 20% more efficient,

a 219c 4000k D240 is 20% brighter
than a
219b 4000k D200

when both are at the same power level

In a multi emitter light, you can mix different colour temperatures of 219c to achieve 219b like tint but keep the 219c efficiency.

The one upside to 219b over 219c is that is has noticeably more intensity/throw over 219c. The difference far offsets the loss in efficiency if throw is what you are after.

Never thought of mixing 219Cs for a better tint. Would 4000K and 5000K be a good mixture? Can you do that with a triple, or does it need to be a quad? I don’t recall seeing anyone doing that here.

I’d rather use my flashlight around the house than turn on the lights.

I tint mixed a Noctigon Meteor M43 WITH 219C 4000K and 5000k, 50/50 , and the resulting tint is a beautiful 4500k with no more green. I have also done it on a quad with the same results. In a triple, it will also work but may not drop your DUV as much since it won’t be 50/50 balanced. In a triple you can even try 3000k +4000k +5000k

Okay just saw this thread and trying to make sense of it. So I have from Kaidomain a 219C (4000K, CRI92) and a 219BT (4500K, CRI92). 219C was ordered 1-1/2 years ago and the 219BT was ordered last week.

So after reading this thread, the 219BT is around 1500 Lumens and the 219C is around 700 Lumens? Is this correct?

Also, which one has more intensity/throw? 219C or 219BT??

if the 219c is D240 it makes 240 lumens, at the reference power level
if the 219b is D200, it makes 200 lumens at the same power level

which one has the tint you prefer?, which one is greener?

depends on the beam patern and power level

If you build two identical lights, you would be able to judge by shining each light on a target, and decide which one looks brighter, to your eyes.

My guess is the 219c will throw farther, simply because it produces more lumens.. brighter but greener..

both the 219c and 219b are similar in dome size, there is not a big difference in the beam they produce

the more significant difference is that the 219c is Greener, and slightly brighter. But the 20% difference is not a significant visual difference, whereas the Green Tint is obvious

no .

In my experience mixing 219c 4000k and 5000k resulted in a neutral white that no longer required a Lee minus Green filter. It is am improved tint that is very close to the BBL compared to 4000k or 5000k on its own. There are different bins of 219c, and can’t confirm which I was using.

So although this mix in my opinion is a good mix, it won’t be as rosy or far below the BBL line like 219b. How far it deviates from the BBL is really a personal preference. The larger the gap in CCT, the lower the DUV will become, but CCT will probably drop as well. Compromise to be made.

Okay, thanks for the info and I’m starting to understand… kinda. LOL I know, I need to do more research on that graph output and will when I have a moment. Big Smile Tint wise, I prefer rosier as the emitter is for my Lumintop EDC18. I’m wanting to replace the XPL HI 5000K which I like, with something warmer for the time being.

Man so many variables for the Nichia emitters. Back in the beginning, I thought okay, just grab a Nichia 219 and I’m all good to go. Then found out about all the options, tints, and numbers! Easy but not easy! LOL

> Tint wise, I prefer rosier

219b is rosier than 219c

however the 4000k 219c is warmer than the 4500k 219b

I personally always choose the 219b over the 219c, because rosy tint is my preference… but

4000k will be warmer and yellower than 4500k, which will look bluer

I would still choose the 4500k 219b over the 4000k 219c, because the C looks muddy, and the B looks cleaner and clearer

so 219b 4500k yes
219c 4000k no

the 4500k 219b is uniquely versatile.. it is the gold standard, for me.. though I confess I have a dalliance with 219b in warmer color temperatures..

Okay, I will try the B out and compare it to the C when the B gets here as it was shipped out already. By the looks of it, I think I will like the C. Will be great because it is getting darker nowadays with Falll around the corner. Smile
