I wish to use a couple of colour matching fluorescent lamps (e.g 4ft 40w
Colour Matching Fluorescent Tube). Unfortunately, these are 40W and 38mm
- which means that they don't fit many standard fittings.

Any ideas where to source a suitable fitting with a high frequency
ballast suitable for these?

A skip?
This size (T12) is effectively obsolete now, having been replaced
by T8 tubes. I also doubt you will find 40W T12 electronic control
gear now, although it might have existed some years back. You will
probably get away with using 36W electronic control gear (I think
both tubes run at 420ma), which you could retrofit into an old
fitting.
