It is a little like getting a Snicker's candy bar in Japan. You fire into it expecting a good ol' USA type Snicker's only to find it has about half the sugar... not what one is expecting... and at first, a bit disappointing, but one may find they like it better over time... we shall see.
Interestingly, American-branded candies in Asia (Taiwan from personal experience) are usually slightly less sweet. Same goes for sodas. Many of them are quite enjoyable.

And then there's this… Diet Coke with fiber…

Sounds like you need to salvage the emitters by dedoming them and selling them as 4300k!

;)
There will be no dedoming by us... unless I can convince Henry, but I doubt he will want to do that. What the end user chooses to do is up to them. I may try it on one just to compare on the sphere... a 5000k domed and dedomed side by side might be an interesting experiment with actual data from the integrating sphere. I'll have 3 built out to play with next month.

I found everything back in the States too sweet when I returned... though that was decades ago. The only "sweets" I eat now is licorice imported from Finland, which isn't very sweet.

Right from Nichia's Data Sheet. The 5700k should NOT be hitting right smack in the middle of 5000k especially with the narrow bin we have. Nichia is either playing silly buggers or figured that since most flashlight manufacturers lie about everything, they might as well join the bandwagon. It isn't how we do things here. It is why we spent tens of thousands of dollars on an integrating sphere rather than $50 on some light meter or better yet, some phone app.
We expect our customers to actually KNOW what they are getting and not give them some regurgitated info from a data sheet... which is often wrong.
Yes, data sheets **** me off when they are inaccurate... so in general, they mostly **** me off, but Nichia's have not been this bad in the past regarding Kelvin temp... which makes me think they mislabeled the real.
It isn't that they are bad emitters. Far from it. The 5000k is very nice in my opinion, and I will be putting some in a few lights for myself to play with, but they are NOT 5700k.

Did you call Nichia and discuss the discrepancy with them?

The rotaries have a stainless switch cap now? Where have I been? When did this happen?

I've removed the dome on a few 519a emitters. I used the slice and scrape method. Pretty easy as long as the emitter is fully exposed. The quicker method of flipping the dome is rumored to introduce air between the glass and phosphor and reduce output. There's also a theoretical a risk of completely ripping the glass off the phosphor.

I suppose the wrong stickers were pasted on some party and someone from the management does not want to admit the mistake. All subordinates are subject to it.

Some large companies hate admitting mistakes, especially such small. For example, what happened in Fukushima and how the engineers and company management acted. Now they generally want to drain the radioactive water into the sea.

I'm waiting for the new NVSW219C-V2 with a flat dome

I received a shipping notification for the NB27 I ordered. I am amazed that it was completed in a week. Did you happen to have parts in stock? Or was the NB45 I ordered last time just extremely late due to some trouble? In any case, I was waiting for it to arrive by the end of June, so I'm happy with this speed.

I didn't realize the standard (black) Rotary cap is stainless steel now. I thought that was just a special run with raw stainless and that the normal part is anodized aluminum.

However, I just held a strong magnet up to the caps of two vintages and found:

2022 Rotary = mildly magnetic = probably stainless steel
2011 Rotary = not magnetic = probably anodized aluminum

Maybe something to do with the thin wall next to the assembly access hole (the small hole filled with a rubber plug)?

It makes sense. Stainless on both ends where it's most likely to land if it's dropped. Aluminum everywhere else.

Now I feel silly for passing on a raw stainless rotary tube because I figured it added weight over the standard one!

ETA...

Aluminum tube from 2011: 37.69 grams
Stainless tube from 2022: 50.60 grams.

For the full light w/16340 installed, it's about a 12% increase in weight overall. (103g old style, 116g new style)

Blackened stainless since May 11, 2020.

It depends on what emitters we have mounted, which one of our staff is waiting to be bailed out of jail, and if one of us is currently on a bender... which might lead to having to be bailed out.

I see, this time it was the result of various factors progressing smoothly. I was lucky because I was prepared for a delivery time of more than 5 weeks.

My (now second) sapphire lens coating on my HDS Rotary has micro scratches again. :(
Emailed two times, no response ...

Same here. I'm not sure if was worth the upgrade from the regular lens. Other light makers that use sapphire, use one side coated AR, (which is installed towards the inside of the light) or non coated.
