As per subject. My other old CRTs go dim but all the trinitron ones go
green. Is there a simple explanation?

The green phosphor tends to be the most efficient, if you've ever seen a
green fluorescent tube you'll see what I mean, the green is about 2x as
bright as the blue and many times brighter than the red.


Either that or the human eye is most sensitive at the green wavelength.



It is, that's the other part of the equation, but the lumen rating is
substantially higher for the green than even for white.
