Westinghouse Fluorescent Tube Colors « on: September 20, 2025, 02:13:35 PM » Author: wide-lite 1000
  I was looking at some old Westy catalogs on Lamptech today and was a bit surprised by all of the different versions of white they listed ! Along with the "normal" Cool White , Warm White and Daylight colors , they also list Living White , Merchandising White , Sign White and Supermarket White .  Anyone ever seen or heard of any of these ???

I have heard of those before. I think some might just be brand names for the same colors that other manufacturers offer.

Sign white is probably 6500K. May be with a special phosphor borrowed from backlight sign tubes having peaky spectrum at red, green and blue, to make sign colors more saturated. Or may be it was just 6500K halo sold under fancy name...

According to this 1979 Specification Guide for North American Westinghouse fluorescent tubes, I see that they list sign white as having a color temperature of 5300K:

Additionally, I have read that these tubes have a CRI of 82. Information is found on page 15.

After reading WWHID's link , It appears that most of these colors are very similar to more "common" colors but with a bit better CRI .

 Living White looks to be 4,300k & 93 CRI

One random thing is that Merchandising White and Modern White Deluxe shared the same abbreviation in order codes of /MWX
