I thought the MacAdam ellipses were inclusive of all the preceding “quadrants”, i.e. sm4050e includes the bottom-right quadrant of sm403, sm4070e includes quadrants from sm4050e and the bottom-right quadrant of sm403. Or looking at it another way, the Rank defines how tight to the BBL the tint is. Is this correct? If so then sm4070e would not guarantee a significantly negative DUV but rather just increase the range of the _potential _ tint further away the BBL.

Hmmm good observation. You might be right… Sad

Any chance of sm4550e 4500k instead/also?


I’ll find out. I imagine this would also be a popular option?

I’d be interested in 10 x sm4550e if they become available.

azhu, I see you updated the OP – you’ve put me down for 219c 4000k but I’m only interested in 219c 4500k (if that happens).

Yes I saw your comment above so I added a note after your name (sm4550e)

I’m pretty sure we’ve never seen a 219C 4500K in a flashlight ever. Are you sure it’s even possible to source this? I realize it’s in the datasheet but sometimes finding these in the wild are like a unicorn.

Yeah I’ll need to find out if these are even available. Currently awaiting a response from a source.

I’m looking at page 5 of this datasheet, where the 4550s stop at R8000. Is that one out of date?

Oh well spotted, I completely overlooked that. That’s probably a deal breaker for me. Let’s see what azhu comes back with.

Yeah if there’s a 9050 4500K 219C I’m totally in. But I don’t think there is Sad

Datasheet might not be up to date.
I don’t know if spec are corrects but RovyVon : The Aurora A6 has a 4500K tint and a CRI of at least 90 thanks to the Nichia 219C R9050 LED.

There has never been 119C/219C 4500K R9050 since it was born and (soon) gone. If there was 4500K R9050, then I must have brought them to BLF. Unless there are special bin which is very unlikely to happen.

If I’m not mistaken, the rank numbers just indicate a minimum CRI value, not maximum.

Ah I never thought of this because R8000 to R9050 is quite a difference. This is the beauty of having a Spectrophotometer Thumbs Up Beer
I really should start saving for one.

For $250 I was able to get a used ColorMunki Photo. It is an entry level model that uses the same sensor as some of the higher X-Rite models. It also goes by the name i1Studio but that model generally costs a bit more. Given your location it may be harder to source a good price used one but worth looking at.

I know myself and 1 or 2 other forum members who use this hardware. I documented some of my early experience with it here and maukka was very helpful in his replies as well:
