Upgrading standard light switches to dimmer switches is a simple way to transform a room's atmosphere and also reduce energy consumption. But choosing the correct light dimmer requires matching your switch technology to your home's wiring and bulb type.
For reference, standard dimmers designed for older halogen bulbs can cause modern LEDs to flicker, buzz, or trip. For smooth, silent dimming on modern lighting setups, you should choose a trailing-edge LED dimmer switch.
You should select a 1-gang dimmer switch to adjust a single light circuit, or a 2-gang dimmer switch to independently control two separate lighting circuits (such as main downlights and accent wall lights) from one plate.
And a 1-way setup operates lights from a single wall location, whereas a 2-way dimmer switch allows control from two different locations (such as the top and bottom of the stairs) when wired alongside a secondary switch.
Match your light switches to your room décor. Explore finishes ranging from standard white moulded plates to screwless designs in brushed steel, black nickel, satin brass, polished chrome and copper.

FAQs
How does a dimmer switch work?
A dimmer switch cuts off the electrical flow to your light fixture, a process called phase cutting. By cycling the power on and off hundreds of times per second (fast than our eyes can see), it reduces the total energy delivered to the bulb, lowering its brightness and reducing energy use.
Do I need a dimmer switch for my wall light?
You only need a dimmer switch if you want the ability to adjust the light output and brightness of your wall lights. If you prefer a fixed brightness level, a standard 1-way toggle switch is sufficient.
Can I use a dimmer switch on led lights?
Yes, but only a dedicated LED-compatible dimmer switch paired with a dimmable LED light bulb will work. Using an old traditional dimmer switch with LED bulbs causes flickering, buzzing and can damage the LED driver.
Can you put a dimmer switch on any light?
A dimmer switch can only be used if the light fitting and the bulbs installed in it are marked as dimmable. Non-dimmable CFLs, standard LEDs, or integrated fittings without dimmable transformers will not work safely with a dimmer switch.
Do dimmer switches save electricity?
Yes, modern dimmer switches save electricity. As noted by the UK Energy Saving Trust, modern dimming reduces the power delivered to the LED, lowering electricity draw.
