Hi,
I wrote to the group a while ago about brands of dimmer switches and
have now opted for an MK single plate 2 gang dimmer. It controls standard
wall lights on one switch and mains halogen ceiling lights on the other.
Unfortunately I could not find the cheap MK model that doesn't cope with LV
halogen and had to go for the all singing all dancing model. Anyway, when I
turn on and dim the wall lights (bog standard bulbs) there is no problem.
However, when I turn on the mains halogens there is a buzzing noise coming
from the switch + the lights themselves (I think it's also coming from the
lights but I could be imagining this). I am used to LV halogen transformers
buzzing as they did in the kitchen of my previous house but I did not expect
mains halogens + dimmer switch to buzz. Is this because I've got an
unnecessary transformer in the equation or am I stuck with it ? Can I buy a
dimmer that will only cope with mains voltages and the buzzing will go away
?

Thanks for any help you can give,
Keith
