Advice needed please

[roman]

Hello,

I have installed 3 chandeliers and 6 wall lights (27 bulbs all together 60W each) under one double dimmer swich (chandeliers under one and wall lights under the other) but they burnt after a while being turned on.

Does anybody know if I need a transformer to make it work and what kind? I would really appreciate all ideas.

Thanks

I found a double dimmer 2 way 1000W on each side. Hope it works. Thank you for all replies
