Any sparkies in the house today? A quick question...

I have some MK grid dimmer units which have failed, and they look to be over £20 each to replace. :eek: There are some Varilight "Uni"-grid dimmer switches at about £6 each, but I need to know whether they'd fit the existing patresses and grid plates that the MK are fitted in.


MK Grid Dimmer

Varilight Dimmer

Will it fit or do I need to think about replacing mounting plates as well?

Thanks. :smashin:
Most grid dimmer modules now come with adapters to fit whatever yolk you have.

However, Varilight are good, but if i had MK, i would fit the same again.

Yu just need to look at how long you have had them for.

You pays your money, you takes your choice.

I've had the MK dimmers about 11 years and out of 6 grid dimmers I have, 4 have failed (refuse to push-on). @ £22 a pop for the MK I don't think Varilight could do much worse @ £6 each!

Thanks for the reply.

Great result for you, it will also help with their R+D to improve future products when they pull apart the failed ones.
