Hi Brains, a question is there any saving on energy by using a dimmer ?
Thankx




Well the lamps use less power when dimmed, they're less efficient too,
but if you need full brightness sometimes and not others then yes a
dimmer will give you some savings, but convenience is the main reason
for installing one.
Light goes down with ~ 4th power of current and temperature
so at 50% light you still consume 70-85 % of full power + dimmer
power. Dimming ordinary lightbulbs is a very inefficient way to
save power. (Sometimes it may look great!! -)-)-) )
