When they first came out you could light a room with them !
But they had a real soft red & to me sucked. A fire engine never
looked right. They often had wickid bad moire, so bad we had
to change a few jugs. Took a few months but they did cure them.
Life on them was almost as good as the CC delta sets so lots
of survivors.

This was very visible on an all-white picture like the Indianhead test pattern, where it would look like a big soft-edged pinkish ring (because when overall focus was best, the absolute best was halfway between the center and edges of the screen.) They worked on reducing the saturation of the phosphors, but I don't believe it could be completely eliminated. I can't recall if they did anything to the gun design to increase spot size a smidge to reduce the problem too.
