Do dimmers save energy?

Wed, 24 Jun 2009 10:06:56 GMT

Hi Elvis, give it to me straight on energy efficiency. If I dim my lights to 50% output do I save half on electricity costs or are there "losses" somewhere that mean I'm using more? I read on a forum somewhere that dimming doesn't save any energy - this isn't true is it? Lastly can you tell me why anyone would want to be a politician?

SELV downlights

Hey Elvis, I got a tiny bathroom with no natural lighting. Yeah, I cut myself shaving all the time. I knew you were going to ask that. So I'm thinking of fitting some SELV downlighters. How do I calculate how many I need and where do I space them in the ceiling for best lighting? Thanks buddy.
