The study was not about preference but about what light when dark adapted looked most "white".
In terms of preference under the black body ... Was the preferred color point at all CCTs in another study.
And here we go, yet another person clueless about the study making a conclusion on it. Your point is what?
Care to provide a link to the studies you are talking about? I just read the thread again, and the only reference to a specific study was to one by the "LRC". Don't know what that is...the link in the OP to a page about HID and "pure white" perception was not a study at all, as far as I can tell. And nothing was listed about the methods they used...
Maybe we are just talking about two different things...I've just been responding to what has been linked to and discussed in the thread...if you have an actual scientific study to reference, that link is long overdue.
My point is simply that you cannot assume that just because one study finds "pure white" (a nebulous term, at best) to be a certain temperature, doesn't mean that you can assume other people will agree. As many posts have already discussed, changing any of a number of parameters in the test can dramatically skew results. And given that it is a matter of opinion anyway, a study cannot PROVE something that is subjective.
If you have a reference, I would definitely be interested, perhaps it will change my mind on the matter. But just repeating yourself, and saying people are ignorant or clueless, is not really adding much to the discussion.
