Dimmers are rather simple-sounding. However, they can be surprisingly useful. As a result, if you haven't added dimmers for your lights, you should give some serious thought to the issue because of those benefits.
Chances are good that you can guess that the single biggest benefit of having dimmers would be a smaller power bill at the end of every month. Simply put, dimmer lights mean that you are using less energy, which in turn, means that you will be paying less in that regard. Of course, this is beneficial for the environment as well. You can't change everything on your own but this is definitely one of those cases where every little bit helps.
Longer-Lasting Light Bulbs
Speaking of which, dimming the lighting puts less of a strain on the light bulbs, thus enabling them to last longer than otherwise possible. Thanks to that, something that needs to be replaced every few months might be able to remain in use for a year's time or more. That might sound like much, but considering the sheer inconvenience of some of the places where lights are installed, that can save you a lot of hassle.
Ultimately, dimmers offer you increased control over your lighting. Generally speaking, that is a good thing rather than a bad thing. This is particularly true because it is easy to imagine some of the ways that increased control over lighting can be beneficial. For instance, dimmer lighting makes it simple to provide softer illumination for a more intimate mood.
