Halogens dimming up and down on their own. Ghosts?

**howie.hill** · 13th April 2008, 03:16 PM

We either have ghosts or something wrong with our electrics. Room A has 4 halogens and an old school single switch with a dimmer. Room B (hallway) also has 4 halogens and a new Clipsal C2000 switch with dimmer.

Sometimes the lights dim up and down from full to practically none on there own in aprox 1 second cycle. This usually happens untill you either turn them off or sometimes if you change the level of dimming it also ceases. BUT sometimes if you dim Room A the lights in Room B actually go either up or down!

Now my electrician tells me this isn't possible. Now check out this video that proves it does happen.

Can anyone shed some light on this (pardon the pun)

Hey cool!!

I'm not an electrician but once I had a very similiar, although not as dramatic problem, involving dimmer switches. A sparky came and fixed it easily - in my case it was a dud dimmer switch from which the lights in another room were looped (ran out).

Looks like you probably have an incorrect or faulty dimmer installed in the hallway. The hallway and bedroom are on the same circuit and this is why when switching/dimming in the bedroom it affects the lights in the hallway.
The type of dimmer used depends on the transformer type. Typically leading edge dimmers are used for older style magnetic transformers and trailing edge dimmers used for the electronic transformers.

Are any of the Lights involved 2-Way or Intermediate Switched.

Just thinking
