Hi Mal,

It's these:
http://custom1.farnell.com/cpc/product.asp?catalog%5Fname=CPC+Catalogue&category%5Fname=&product%5Fid=261650
(conveniently the website makes no mention of Crouzet, so can't search for
it with that term :-((  )

It talks about a PWM output, and it will accept 0-10V analogue inputs so
you may be able to sort your dimming solution out. Otherwise, have some of
the outputs wired through manual dimmers in fixed positions and select
which output is enabled based on your time-of-day criteria.

Anyway, just a thought :-)

Tim.
