In my front room I have 4 wall lights. Each light takes 2 G4 bulbs. I've put some 2.5w dimmable LED bulbs in them and they work fine. However, I want to make them dimmable and currently when I put an LED dimmer switch on the lights just flicker. The only reason I can think this isn't working is because the bulbs need a dimmable LED transformer. There isn't much room in each light fitting in which to put a transformer (5x5x2cm max). There's also barely any room behind the switch.
The only way I can think to do it would be to smash out the knockout box behind the switch and then somehow mount the transformer to the stud wall. Not really sure how I'd achieve that though. Any advice on this would be appreciated.
