If you want something more complete, have a look at
http://catalogue.maplin.co.uk
and search for CK23A in the order code=20
section- looks like a sensible solution- costs about =A330, about 1"
cube,=
=20
and seems to integrate most of what you need for wired control, copes with=
=20
lights from 10W to 600W, and 30A x 10ms surges.  It's 0-5V (or 0-1)
instead=
=20
of 0-10, but that's easily modified if you already have a suitable
controll=
er!

I've not used one, but the data sheet looks promising=20
https://catalogue.maplin.co.uk/help/pdf/files/zax27.pdf,
it might be worth=

considering (bearing in mind that once you try one and like it, you
could=20
probably get them cheaper in quantity elsewhere!)

OTOH, if you have plenty of time on your hands, the hut.fi one will=20
probably be a bit cheaper- I'd guess around =A310 per channel excluding
cas=
e=20
and PCB?

I hadn't noticed that part before- I'm thinking one of those connected=20
straight to a PIC would open up a lot of possibilities...
