    I was working in a kitchen taking quarry tiles of a floor. I had the light on all day. I sensed a burning smell and thought it was one of my power tools. However, as the light seemed to have dimmed I looked up and saw this!
    The bulb still worked (the light was dimmer due to the mass melted over it). All parts of the holder/wiring were all in tact. It did not trip. A new (clean) bulb is working too.
    Any ideas what caused this??
    :confused:

    Have a look at the light fitting and see what's melted.

    Bulb wattage (and thus heat) too large for the shade / fitting?

    Most likely, it's the white plastic cowl around the socket that's melted.

    That's crazy, that plastic is supposed to be a thermo-set rather than a thermo-plastic! (that is to say, a plastic that won't melt/bend but goes straight into burning).

    Perhaps you've hit the nail on the head with "supposed to be". Could we be seeing the results of using a fake (as in non-BS) lampholder?

    I was an apprentice telephone engineer when I left school.

    At one stage I spent a while at a large group switching centre in Esher, Surrey.

    On the first floor was a big manual switchboard with probably 40 or so all female operators. The best job was changing the jacks and jack cords when the wore out. Each cord had a counterbalance weight under the switchboard. To get to this one had to crawl around among a sea of loverly ankles…

    Oh, Matron!

    ;)

    Never mind the ankles. What were the higher-up bits like? ;)

    I know, trust me to lower the tone.

    A telephone engineers' joke there....
