Do they save any electricity?
To do my bit for the planet I've changed some of the lights in the pad to those low power fluorescent ones. There are a couple of rooms where I don't want to switch to low power and I wondering if the light dimmers make a difference to cost of the bill?
Do those low power bulbs work with dimmer lights also?

get some candles - helps save the planet and looks less cheesy than dimming the lights when one is 'entertaining' a lady
yeah, yeah, yeah

No they won't make any difference I don't think - you'll just be increasing the resistance in the circuit. If anything that cause increase use of power i reckon.
You used to speak the truth.
But now you're clever.

fluro isn't dimmable. but of course you can save energy by using a dimmer by halogen or ordinary bulbs.

Or just close your eyes?
It's never completely dark in Hong Kong anyways, even after turning off all the lights.

are you sure about that? then why does a dimmer get "hot" i thought because its consuming up the power you dont want to send to the light. or is that old fashioned and in newer dimmers not anymore the case?

You cannot use energy saving bulbs with dimmers thus cannot save much energy.
I'm yet waiting for that happens one day that energy savers can be used together with dimmers.

I thought the dimmers got hot because they are cheap ones. The more expensive ones don't seem to get hot from my experiance !!!
Also if you have to many lights through a single switch, they will get hotter also.
If you have got any problems with this site send them to Support@HKExpats.com Thanks

No, they do not use electricty unless your dimmer not generate heat which he shouldn't do. if he create heat, ofcourse he will use electricity, but very very little anyway.

Just in case anyone is interested, light dimmers basically switch on or off at times throught the AC cycle changing the waveform to the light thus sending less power. For example, the incoming sine wave might be turned off for 5 milliseconds after each zero crossing. There are resistors in the circuit, but they don't act as voltage dividers.

i thought they worked as a resistor that is why they have the ventilation holes at the top of them.
