  1. We have inherited premises with a number of Fitzgerald batten gittings T8 x approx 450 mm long. I am told they are not made anymore – is this true. How do you get rplacement tubes?
    If all else fails what is best option to fit a space approx 550 mm wide where obviously a 600 mm fitting wont go?

    1. You’re right, the fittings are no longer manufactured, but the tubes / lamps are still available for purchase. If the fittings are good, all you need to do is to buy the standard T8 tube with that length. One of the best ways to do it is to go to your local wholesaler(or visit us in Archway, North London) with one of the lamp tubes and purchase at least 1 or 2, then try them on…
