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.
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.
