Dimmer Switches

When choosing a dimmer, there are a few different options that you can choose from. The two main dimmers to choose from are a single pole and a three-way dimmer switch.

A single-pole dimmer switch, also known as a single-pole single-throw (SPST) switch, controls a singular circuit and is either "on" or "off." These dimmers are usually ideal in places with a single point of entry including a bedroom, bathroom, or office.

On the other hand, 3-way switches – also referred to as single-pole switch double-throw (SPDT) switches – alternate between two circuits instead of keeping a light "on" or "off," meaning the light can be changed in two separate locations. These dimmer switches are usually used in locations such as hallways or stairwells. You can also find four-way switches for multi-location lighting.

Not all light bulbs are completely compatible with dimmers, but many are! If you are wondering if a bulb will work with a lamp dimmer, check the packaging to see if it’s compatible. It should have "dimmable" or “dimmable LED” written somewhere and the amount of energy (wattage) it can handle.

Many fluorescent bulbs will not work with dimmers or will have some side effects including the bulb color having more of a cool look when being dimmed. Even though you are dimming the light, it will not prolong the life of a compact fluorescent lamp (CFL) bulb. The main bulbs that are dimmable are LED bulbs and incandescents. You can use a halogen bulb with a dimmer switch, but it may reduce the bulb’s lifespan. Some LED dimmer switches will only work with an LED bulb, but you will have to read the labeling of the box or go on the company's website to see if there is a specific pairing.

There are several advantages to using dimmer switches, including:

• Cost savings: Switching to dimmers can save you about 10% on your utility bill
• Fewer bulb replacements: Dimmers reduce the amount of power delivered to the light source, so they save on energy and can extend the life of the bulb.
• More control: You’re able to regulate your lighting the way that you want.
• Low maintenance: Once installed, in-wall dimmer switches require little to no maintenance.

Before you install a dimmer switch, turn off the power at the breaker. You can also use a voltage detector to test for live wires before doing any work. Once the power is shut off, unscrew your old switch plate and remove the old switch. Follow the instructions on the dimmer switch to swap it in. If the switch has pre-attached wires, connect them using wire connectors.

Once the wires are attached, fasten the switch to the electrical box and screw in the switch plate. Turn the breaker back on and test your light. Note that if you’re installing a smart switch, you’ll likely need a neutral wire. Call a licensed electrician if you’re not sure your wall box is up to code.

• Dimmer switches come in many different styles to coordinate with your existing decor and suit your needs:

  Rotary control: These feature a dial that is used to change the brightness of the light. The lighting levels can be adjusted by turning the dial from left to right. The light will achieve full brightness when turned to the far right position and will be at its dimmest when turned to the far left position.
• Slide control: A slider offers precise brightness control for your lights. Full brightness is achieved when the slider is at the top of the switch and the light is dimmest when the slider is at the bottom of the switch.
• Remote control: Handheld remotes have also become a very popular option for lighting control. They can dim your lights wirelessly and have different ambient settings for you to choose from.
• Paddle controls: These are a simple up/down, on/off type of wall switch with a sliding control on the side for dimming.
• Rocker controls: A rocker control has the same function and looks very similar to a paddle control in its simple design, but is designed to be more decorative.
• Smart home switch: These switches often come with a proprietary app, like the Lutron Caséta system, so you can adjust lighting from a phone or tablet.
• Toggle control: A toggle switch looks just like a regular wall plate light switch but has a slide control on the side for dimming.
• Touch switches: These are the most advanced type of control and take advantage of the recent touch technology. By simply sliding your finger up or down on the smart dimmer switch’s touchpad, you can control lights and adjust the brightness in a selected room.
• Z-Wave: This is a type of smart switch that connects to your Wi-Fi so you can adjust your lighting remotely from anywhere in the world.

Most dimmer switches come in neutral colors like white, ivory, or light almond.
