Originally i had 2 spot lights running of a normal on-off flick switch. I wanted to be able to dim them, so proceeded to change the switch to a dimmer switch. Before I turned the electricity back on i noticed that the transformers above the spots were "non-dimmable", so i chnaged them for dimmable transformers and at the same time changed the light and wiring arrangments for new ones. I then turned the electricity back on to find that the lights didn't come on at all. I read the instructions for the new lights to discover that they are "dimmable without the need for a transformer", so i removed the tranformer from the circuit and wire it as the instructions said. The lights now come on, but they are not dimmable. I know the switch is OK as it came straight out of service in my lounge where it worked perfectly well. So, does anyone have any ideas why the lights won't dim?
