DALI, 0-10V, ?

My parents have a lighting installation in their living room which
is about 40 years old, consisting of 3 x 6' T12 tubes behind a 19'
long curtain pelmet, running from Transtar control gear (which I
presume from the starting behaviour is either rapid start or
semi-resonant start gear, but the control gear is completely potted
so I can't tell for sure). (This is UK 240V mains.)

They don't use these lights because
a) they don't like the colour rendering, and
b) they are too bright much of the time.
I looked at the tubes, and they are Philips colour 29, which has
really poor colour rending (51). Tried shopping around and no one is
stocking 6' T12 tubes anymore, and what stock people did still have
left was 3500K as 6' tubes are rarely used in homes, rather than
2700K which I'm looking for in a living room when mixed with filament
lighting. So it seems to me that there's nothing in the form of tubes
or control gear which is worth saving here, and I might as well start
again.

So I'm thinking of what I want in a replacement system. I want a
system which is dimmable, and an IR remote control dimmer would
be nice. It would be difficult to use anything other than 6' tubes,
but I will probably use T8 as T12 are all but obsolete in the UK
now, and there are no T12 fittings or control gear available now in
any case. So I guess I'm looking for a 0-10V or DALI controller
which handles a remote, and suitable electronic dimming ballasts.
Ballasts I can find, but has anyone got recommendations for a
suitable dimming controller?

Also any recommendations for 6' 70W T8 tubes with a 2700K-2900K
colour temperature and CRI of at least 80.

Drop me a line at my work emnail addy below and I'll sort you out some
lamps, ballasts, controls etc on Monday. We always have a good pile of
'spares' in the lab.
