Will a Dimmer SAVE Power and Money?

Author: Andrew Aranovitch  

Yes, it will save both electricity usage and some money.

When you dim a light it actually reduces the electricity usage and saves you money.

-The answer lies in the way a dimmer works

It has a Triac semiconductor that switches the current on and off 100 times a second.

When in the off position  - no electricity gets used and the light is off

When in the on Position  - Electricity gets used and the light is on

Therefore the longer the light is in the off position during the cycle - the lower the light output will be and less electricity will be used.

If the lights are being turned on and off 100 times per second - why can't we see the light flickering?

We can't see the flickering because the light level is smooth and constant.
Compare dimming to a movie projector. A movie is actually 35 individual frames per second, projected so quickly that you can't see the break between frames. The dimmer operates almost 3 times faster.

So how much electricity can you save?

10% Dimming  = 10% Electricity Savings = The bulb will last 2 times longer
25% Dimming  = 20% Electricity Savings = The bulb will last 4 times longer
50% Dimming  = 40% Electricity Savings = The bulb will last 20 times longer
75% Dimming  = 60% Electricity Savings = The bulb will last 20+ times longer
