"When I buy light bulbs they always list the color temperature but not the lumineous flux, what's the relationship?" Hi! LED and LASER module design and manufacturing tech here! There is a small correlation with LEDs and luminous flux - the ones with higher green peaks (2700K-~4000K CCT) will have a higher luminous flux at full power as green (~552nm) is where the lumen is weighted and those tend to have more output in that converted color range versus the cool white (which have a little less green and a bit more blue.) This really only applies to phosphor-converted LEDs, RGB combo LEDs are narrow-spectrum in emission, and you can't really describe them by luminous flux, rather photon flux or radiant flux per output channel, as the luminous flux will always be highest from the green LED, no matter what, due to the weighting of the lumen in the green wavelengths.
