Illuminance: Brightness Numbers

Illuminance: "Brightness Numbers"

Let's please have a debate here.

Do we need a new comparison measure, to replace lumens in consumer selection of most-efficient lighting?

I have sought to inform the selection of LED lighting to replace incandescent and CFL point source bulbs through reported unambiguous side-by-side comparisons. In this I have suggested that a "Brightness Number" be used as the alternative to lumens count. All of my writing in this blog, on this subject, may now be selected through a a new post Label definition, Brightness Numbers .

I think US Department of Energy has the paid-for responsibility to cease misinformation here:
