    Fluorescent lights and relays

    Hi all, I've just been to test a number of faults and have found a number of classrooms have relays on fluorescent lights? Can anyone think of a logical reason why someone would have installed them like this? Thanks in advance.

    Changing fluorescent tube fittings to pendant.

    Hi, I have removed 2 strip light fittings from the attic ceiling and would be most grateful if anyone could give some advice as to wiring some pendant fittings. The single wire seems straight forward but am not sure what to do with the double wires. Many thanks
