Choosing a Dimmer

Note: For instructions on how to properly wire a light dimmer, please refer to the article on wiring a light switch.

 

Another easy home improvement project is to swap out a regular light switch for a dimmer.  Most dimmers are relatively inexpensive and will eventually pay for themselves in energy savings.  Not to mention, there are times when you want a dimly-lit room (e.g. while you are watching television).

 

 

There are a few characteristics to consider when choosing a dimmer.  First, determine if you need a two-way or a three-way switch.  Make sure the dimmer you purchase matches your needs.  Next, do you want separate controls for on/off and dimming?  Many dimmers have separate controls for on/off and dimming.  This allows you to keep your dimmer at the same setting at all times.  When you turn the light on, it will be set at the same level as when you last turned it off.

 

Also determine if you need a heavy duty dimmer.  Let me give you an example.  A couple of years ago, I bought a dimmer that was rated to handle up to 600 Watts.  I wanted it to control a chandelier that had nine 60 Watt bulbs.  A total of 540 Watts- no problem, right?  Wrong.  Even though it seemed to function properly, it made a constant humming noise whenever the lights were dimmed and the dimmer was hot to the touch.  So I exchanged it for a dimmer that was rated for 1000 Watts.  That made all the difference in the world.  It looked identical and functioned exactly the same, but didn't hum and was not warm to the touch.

 

Finally, decide on the bells and whistles.  I love my remote control dimmers, but they cost twice as much as my regular dimmers.  Do you want 8 steps of dimming or 16?  Do you want a tiny little light on your dimmer so that you can find the switch in a dark room?  Those are some things to think about.
