Dimmer switches work by reducing the amount of current that flows into your light bulbs and they are considered energy savings.
While the total energy saved depends on how much you dim the lights, how long they are dimmed, and which types of bulbs you choose, dimmers are also a great way to control the vibe of a room whether you want to watch a movie in the family room or host a dinner in the dining room, dimmer switches can enhance the atmosphere and set the mood.
They will make light bulbs last longer – the softer the light, the longer the bulb lasts.
You can add between three and four years to a bulb’s life with proper dimming.
