The recent thread about blowing bulbs reminded me of this:
Some years ago I fitted a pair of touch dimmer switches from TLC:
These are for for ceiling lamps in our living room. These were originally
'standard' light bulb fitting; I have since replaced them with two fittings each
with 3x Halogen g9 40W bulbs.
Cut to a number of years later, and over a period of a year or som, both dimmers
got less reliable (light would cut out on its own etc.). Eventually I replaced
them both with the same item.
One of these works fine. The second dimmer seemed to fail after a week or so
(light failed to turn on when touch place pressed) and I returned it to TLC for
However there seems to be more to it than that; What seems to happen is that
after a few days the replacement dimmer also stops working. If I then trip the
mains MCB for that lighting circuit, and re power it, it is fine ... for a few
The wiring to the dimmer is solid and I don't think anything else has been
changed in the lighting circuit.
Assuming I've not just been unlucky with dwo dodgy dimmers, any thoughts as to
what might be causing this? I originally wondered if the load might be too
little but the switches are rated at 60W minimum...
Thanks a lot
