    I've had my low voltage down lighters installed for about a year now. Over a short period of time I've had 2 failures which appears to be the mr16 lamp holders.

    I've purchased some new lamp holders but I'm not sure how to swap these over as the low voltage transformers (jcc 4030) are prewired from the factory.

    Any advice would me much appreciated.

    Thanks.

    If pre-wired directly on to the lampholder tails!
    Then isolate circuit, prove circuit is dead at primary supply side, using an approved voltage indicator (two probed/pole)
    Cut into tails on secondary side of trany, strip conductors back, connect each tail of lamp holder to tail of trany in a connector, enclose connector within a enclosure such as a choc box. Then re-energise, if lamp does not work and connections are good, then it is likely the trany needs replacing also.
    The cables of the the lampholder should be secured in a manner that prevents heat dissipated from the lamp effecting them.

    All sorted now thank you.

    Tempted to swap these for led units in the near future as they run so hot.

    Wise idea, the LED products have made vast steps in recent years.
    A little more expensive but in time you will get your money back and you will immediately reduce the risk from heat!

    You may also have to change the low voltage drivers to LED compatible ones.
