    hello
    3 days ago I replaced 2 halogen bulbs in my bathroom with 50 watt ones.
    previously I had 35 watt but it was always a bit too dark.
    3 days it was working fine and after that the whole lighting system went down..
    it's not the fuse as I checked, I have lights in the rest of the house as normal.
    could the fact that I replaced 50 watt instead of 35 watt be the reason at all?
    how to fix this?
    there are 3 bulbs altogether and it a normal UK 'string' system
    I have no idea where to start with this.
    any advice much appreciated..!

    Your bulbs was on 12VAC or 230VAC. If 12V you damege halogen transformer. Check the thermal fuse on it.

    I think it's very possible it was 12V.
    how expensive is to change the fuse on transformer? and can I do it myself?
    many thanks

    If 12V there are two possibilities

    1. the transformer is traditional with thermal fuse like this

    the fuse is under adhesive tape between the wire's [ in poland you can buy it for 1,5 PLN its few peny in UK ]

    2. the transformer is electronic like this

    and you have to buy brand new for higher power if you like to use 50W bulbs

    check your wiring for melt or bridge contact

    yup. If it's not the fuse, probably the change in the bulb's voltage caused the problem.. some incompatibility.
