I recently moved into a new house and have had 5 halogen light fittings fitted, they are 12v fittings which are fitted with a step down transformer, they are not fitted to dimmer switches just standard switches. I purchased from a well known high street store and have had an electrician install them. 2 weeks after fitting them one stopped working so I replaced all the bulbs and still nothing. I had the fitting replaced and that is working fine now. Now the same has happened to another 2 fittings. The wiring in the house is 6 months old and the fittings have been wired correctly so I am a little unsure as to why this keeps happeing.
If anyone has any ideas or suggestions I would be very grateful.
Many thanks in advance
