Does anyone else think that the modern 2100lm 87 CRI “Utility Cool White” lamps, as GE calls them now, seem to be more blue and have a higher color temperature than the older 60 or 70 CRI tubes. I was wondering if that is just the way the phosphors are, since I don’t have a 2900lm 87 CRI lamp to compare it to, or if it is a problem unique to the 2100lm lamps. I might just be seeing things though.

If it is true that they do have a higher color temperature when you look at them, they would make a great replacement for the old “4500 White” lamps from the 1940s, as those also put out 2100lm.

I think they are supposed to be 4100K but because they use deluxe phosphors and the fact it is often applied very thin it makes the colour bluer. I notice this in the Sylvania CWX especially the 34 which looks more violet

I note the CWX, C41, etc etc looks more purple, as LightingGuymentioned.
