<p>Andrew,</p>

<p>The url you gave leads to a page where you cannot sign up as a member, you only can sign in or unsubscribe. Mail to <a href="mailto:mailman@list.apple.com">mailman@list.apple.com</a> is undeliverable. I'm stuck.</p>

<p>I guess you have to be a color scientist?<br /> OR: <br /> https://lists.apple.com/mailman/listinfo/colorsync-users</p>

You wrote: "I guess you have to be a color scientist?" I guess you can't help yourself making these kinds of jabs? One more and I'm out.</p>

<p>Anyway, I registered and all I see is that I can send an email to the ColorSync users list. Then what? Are respondents going to email me back with their replies individually or is there a place like this forum where everybody who signed up can look at all the interactions? </p>

<p>You send email to the list! The list gets the emails. They reply. You get the email(s). You reply back. Haven't seen any email from you through the list. </p>

<p>Additionally: IF you have more than one email address, you must use the one you signed up with. If you reply using another email address, (email host uses a differing one as default) it will bounce back. </p>

<p>As promised (and mentioned in your new thread): Unit failed CCT:</p>

<p><img src="http://www.digitaldog.net/files/Solux4700K.jpg" alt="" /></p>

<p>This is a 4700K bulb in a Solux lamp they themselves sell, not my own rig. So if you don't like the results and feel it's something to do with how the bulb is housed or installed, this is a 100% Solux solution with no other modifications. </p>

<p>Andrew,</p>

<p>Have you worked with Phillip Bradfield or Kevin McGuire at SoLux to resolve the issue and what was the result?</p>

[digitaldog]

<p>Let's stick to one thread or the other, no need to repeat everything in two places. I addressed your needs for measurement data and I answered your last question the first time asked in that other post. There's nothing to resolve. </p>

<p>I got an email from the author of the paper I referenced here that is for the CIE. The paper is up for public consumption at: <br /> http://www.abhijitsarkar.com/documents/Papers/SarkarBlonde_2013_Colorimetric-observer-categories_CIECentenaryConference.pdf<br /> It dismisses a lot of Franz's idea, the reason he hasn't replied back here after having had access to that paper for 10 days now. Abhijit has read Fran'z paper and had a number of issues with it and we are in agreement on his misunderstanding of D65 as a CRT legacy, gamma etc but no need to go much farther. <br /> Franz's ideas of 5000K for both print viewing and display can be easily dismissed in just the first two pages of this paper, something I originally posted on before Franz took us down this huge and unnecessary digression on Solux CCT ratings in two forum posts here on PhotoNet and over on LuLa.</p>
