    Bit of a weird one this but can I use something like this http://www.tlc-direct.co.uk/Products/VE753.html to power a light fixture which has 2x 8v 2w miniature candle bulbs in it?
    The existing one is knackered and the light manufacturers are shut until 4th Jan and even when they are open they take an age getting back to you.
    I don't fancy just trying it as the lamps are in the region of £40 each apparently :eek:

    2W they are small :eek: yes it should work with such small lamps, Freidland make bell pushes containing a small festoon lamp for illumination.

    I would advise first measuring the voltage coming out of the transformer. Although rated as 8 volts it might be higher than 8 volts.

    Also these are seldom rated for continuous use ( in that the bell push is pressed continuously ) and may run hot if continuously supplying 4 watts of power.

    Yes they will continuously power a small lamp in the bell push but that lamp is a lot smaller than 4 watts.

    You'd be better off with something like this:

    http://www.tlc-direct.co.uk/Products/SK660095.html

    You can set it to 7.5V. I'm sure half a volt won't make any really difference, and it has plenty of capacity for your lights.

    It's a lot cheaper than a bell transformer too.
