Talk:Color quality scale

Untitled
This article is very incomplete, and is NOT neutral as it gives de impression that the NIST work in progress ("possible answer to the criticism of the widely used color rendering index") is an advancement, when in reality, the NIST proposed "CQS" (Color Quality Scale) is trying to make the newer commercial offerings in LED lamps (and CFL'S -Compact Fluorescent Lamps- could be helped also) LOOK better in numbers! While the NIST investigations and future proposed standards have some merit, they contain serious loopholes at the same time, that mostly tend to make the newer lamps "score" better in the numbers. It comes with no surprise, since the scientists at NIST are being "helped" by the lighting industry, no less(!) as it is mentioned in their webpage: "A Color Quality Scale (CQS) is being developed at NIST with input from the lighting industry and the CIE (International Commission on Illumination)"...

And thats not all; it continues saying: "...to address the problems of the CIE Color Rendering Index (CRI) for solid-state light sources and to meet the new needs of the lighting industry and consumers..." (SO PUT THE INDUSTRY NEEDS AHEAD OF THE CONSUMER!)

A couple of examples will show that the proposed "CQS" have indeed manipulations of the criteria in order to make some technologies "score better": (taken from the webpage of the NIST:) QUOTE: "Problem: The CRI penalizes lamps for shifts in hue, chroma (chromatic saturation), and lightness, in all directions, of the reflective samples under the test source (compared to under the reference illuminant).

Solution: The CQS will only penalize a lamp’s score for hue shifts, lightness shifts, and reductions in chroma. Lamps that increase object chroma relative to the reference illuminant are not penalized because these positive effects are generally preferred."

REALLY???

Another one: "Problem: The CRI can result in negative values for some lamps. Solution: The CQS imposes a 0-100 scale."

GRRRREAT!!! Lets save some poor color rendition products by eliminating their NEGATIVE C.R.I. values!!!

The terrible color rendition of many of today's CFL's and LED lamps needs to be fully exposed, so that the consumer is aware and avoids wasting money in underdeveloped lamps, all in the name of the ecology and preservation. amclaussen.

 * First of all, the talk pages is not a blog for personal opinion on the subject of the article. Secondly I find the use of what I must assume to be irony to be highly misplaced here. However, you bring up some interesting points, if you deem them notable put them in the article, but please keep your personal commentary away from wikipedia - it is neither needed nor appreciated. --Thorseth (talk) 13:06, 17 July 2011 (UTC)
