Anyone know where I can order a T5 ballast? to run a single 54w T5 tube.

Best I can find is "Watford Aquarium" who want £25.84 for a Osram
Quicktronic Ballasts. I am sure this should be cheaper if it wasnt an
aqurium supplier - yet the local suppliers I have asked all do not stock T5
fitting?

Assuming you're in the Watford area, try Polar electrical

Buying from specialist shops (even if I know the owner) is normally not
a cheap option
