Am breathing nichia!

Technically 219a and 219b r9050 are rosy as well. That's what Nichia was all about. However r9080 definitely has more red but i wouldn't say rosy

I didn't know there was an sw and swk. Does that mean sw is r9050 and swk is r9080?

I am 74 and not into flashlights other than having a bedside 6P with recently purchased Malkoff cool white M61 dropin thanks to me re-discovering this forum. I have always thought the brighter the better. I want to thank you guys for educating me on the beauty of the warmer tone offerings. I recently purchased from another forum member a MD2 with a 219BV2 Nichia dropin. All I can say is WOW, what a difference when compared to all my other lights. I have a new favorite color choice.

Yep, that's how it starts ...

Maybe it would be worth deep diving into Color Temp and Tint.

First things first, color temp are tint are not the same despite many people using them interchangeably.

Here you can see the two dimensional nature of these two and how they relate. If color temp is a line on which a light falls warm to cool then tint is a perpendicular line to color temp and describes the quality of green to magenta. The color temp line is called the black body and the closer a light is to the black body the more neutral the tint. By definition the higher the CRI the closer to neutral tint a light will have. Remember CRI is a measure to how close a light is to ideal, but high CRI is no guarantee to a neutral tint.

All this being said what does this mean to our lights? Well manufactures place LEDs into bins in which they expect the light will display. Nichia has a page on how they bin here: https://www.nichia.co.jp/en/product/led_color.html

So lets take a look at 219A and 219B tint bins:

So we can see that a emitter can actually have a lottery but we would expect all emitters to fall somewhere in that area.

Now enter the SW45k which is a special bin:
On average we expect an SW45k to be more rosy than an SW45

Does anybody know where one can purchase 219b LEDs particularly in the 4000k cct?

 

[WalkIntoTheLight]

Of course it would work well, but it would depend on the driver used. For example the 219B isnt a big fan of being put behind a FET driver especially with a high drain cell. The same can be said for the 219C but it is more resilient.

219C quad-emitter lights with a FET driver are pretty popular. It seems to work well, even with a high-drain cell. Gets really hot, really quick, though.

Nothing but Nichia!

9080 means minimum 90 CRI Ra, and minimium 80 CRI R9 (red)
Tint is a separate factor than CRI. Rosy is a kind of Tint. Red is a kind of CRI.

Some N219b are more Rosy than others.
Some N219b have more Red CRI than others.

the middle light is sw45:
it looks rosy right? and the 219a 4500k 9050 on the left does not have pink tint at all, see that?

now look at the same light that is in the middle above, second from left below, next to an sw45k.
the sw45 is Less Rosy than the sw45k, but they are both 4500k color temperature and both are 9080 CRI

219b 4500k 9080 sw45, has more pink tint than 219b 4000k 9050

I lived with the 219b 4000k 9050 for several years, in Maratacs, Tools, and modded lights.
then one day I met the sw45k and I thought it was waaay too pink. Now I LOVE it, and think the 219b 4000k 9050 is waaay too yellow.. lol!

Im not consistent, my preferences change depending on the time of day or night

I like 3500k at night, but find the color too warm during the day..

I'm not consistent, either. I find that if I don't fancy a particular emitter, all I have to do is wait a while and I will discover an appreciation for it. The 219b 4000K R9050 is straight up yellow. Nothing rosy about it, no matter how many beams I cross. At first, I didn't love it, but now it's my night time creeping light. Too warm for anything else.

Would you have gone 4500?

 

[Modernflame]

Would you have gone 4500?

Oh, yes. Although I have room in my heart for both, I prefer the 4500K R9080 (sw45). Sometimes it does look a little too pink, but I only notice it when the ambient light is much cooler. It's perfect outside at night.

 

[INFRNL]

thanks for the insight on the differences in emitters.

I agree with what modern is saying as others also have. To me the 219b r9050 is my go to, but there are different times of day or particular tasks that I do prefer the other emitters. there is no one emitter for all scenarios

well said, I feel the same

I have lots of different lights with N219b, some 3500k, some 4000k,
the majority are 219b 4500k 9080,
and that is the one I EDC and use most, it is my personal grail LED

nothing wrong with the 4000k, at night
during the day.. not my first pick

 

[NPL]

Has anybody ever mixed 4000k and 4500k 219b for a mixxed cct closer to 4250?

Anyone tempted by an EagleTac D25c 2015 219b, PM me for a link.. not affiliated

What colour temp? 9080?

 

[INFRNL]

it's the 2015 model so it should be R9050 and should be 4000k if I recall correctly
