I installed a new set of lights from Next about a month ago called Lana. They are supposed to use 20 Watt G4 bulbs, I made the mistake of putting in 25 Watt bulbs in and it seems to have created a problem. Despite restoring the 20 Watt bulbs, the lights now go off after about an hour. Can anyone suggest what could be the issue and how I can resolve this please?

Thanks

G4 lamps, would suggest 12V transformer.
Transformers normally have a maximum rating, as you have exceeded the required/maximum rating as instructed by the manufacturer, by using 25W lamps instead of 20W lamps, You could have overloaded the transformer, it could well now be that you need to replace it.
