Last warm white LEDs I tried had even poorer colour rendering than 'white'. And a rather unpleasant greenish hue. Warm white - to me - means a bias towards the red end of the spectrum.

This is a topic driven far more by folks with an axe to grind than by science, a combination which doesn't make for quality Wikipedia pages.
I've been using Osram Silverstar for years and they actually do what's claimed. Not sure about the blue-tinted bollocks, though. Mostly bullshit, I would suspect.
Thanks to everyone for their advice. In the end I've put up some new fluorescent fittings with high frequency ballasts and everyone who's seen them so far admits they can't notice any flicker. Can always bypass the ballast and retrofit LED tubes later.
