I have a big ceiling light, with 30 small 10W 12V G4 bulbs. I haven't had it installed yet, but wanted to ask if it would be safe to use a dimmer switch with it (30 bulbs might be too strong otherwise). I don't want to damage the transformer as the light was very expensive.
It has a very heavy transformer. It is round and has a diameter of about 20 cm. Is that likely to be a "wire-wound" transformer?
I bought a 400W dimmer, but it says not to use with a wire-wound transformer.
I have rang several qualified electricians and they all give me completely contradictory advice. Some say it is dangerous to use a dimmer with such a light while others say it is perfectly safe and won't damage the light as long as I use a dimmer with more than 300W.
