This is primarily a single pole switch, which means it’s easiest to use in a configuration where it doesn’t share control of the lights with any other switches. It is possible to use in 3-way installations with a mechanical switch, but that takes a little extra work. It requires different wiring from a traditional dimmer switch, so you’ll have to discard your preexisting knowledge and pay close attention to the instructions if you’re familiar with how 3-way wiring is supposed to work. The hidden benefit is that this switch is actually designed for multi-location dimming in up to 10 locations if you use Maestro Companion dimmer switches instead of traditional dimmer or mechanical switches. This white dimmer switch features intelligent dimming technology, soft start, intelligent overload protection, and adjustable minimum brightness settings. It comes pre-set as a trailing edge dimmer with three programmable modes to cater to a range of LED requirements. Flexible Lighting Control: You have the convenience of adjusting the light intensity to match your mood or specific tasks, enhancing your home’s comfort and functionality. This article was written by Jeremy Laukkonen, a freelance writer for The Spruce. Laukkonen has more than a decade of experience writing about and reviewing consumer technology.

Leading edge dimmers are the most commonly used to dim incandescent and mains voltage halogen light bulbs and capsules. They are also used to dim most electronic low voltage transformers, including wire-wound or toroidal transformers and can also be used to dim constant current dimmable LED drivers under certain circumstances that will be explained later.They are commonly used to dim most electronic low voltage transformers (ELV) with capacitive loads on the primary circuit. Trailing edge dimmers can also be used to dim incandescent, halogen and LED lamps effectively. They should not be used on older type of magnetic core and coil wire-wound or toroidal transformers. Dimming fluorescent fittings is complex and can involve analogue or digital dimmers and a variety of different wiring schemes. These are expensive to install and are mainly used for commercial applications and are beyond the scope of this article.

For example, the Kasa HS220, our best smart dimmer, works with Alexa and Google Home, but not with HomeKit. If your smart home is powered by Apple’s HomeKit, you’ll find that the Kasa HS220 just won’t work correctly. In that case, consider the very similar Kasa KS220 that works with HomeKit.On the other hand, mains voltage dimmable LED light bulbs and LED light fittings can be comfortably controlled using standard resistive dimmer switches. LED lamps are particularly appealing due to their low energy consumption and high energy efficiency. Dimmer switches allow you to adjust the brightness of light bulbs. They adjust the amount of voltage that reach the bulbs. So, for example, the more voltage the bulb receives, the brighter it will be. What to Know Before You Get Started There are no 4-way dimmer switches, but this kit from Leviton is functionally what you’re looking for if your goal is to operate and dim your lights from three or more locations. The reason 4-way dimmers aren’t possible with traditional switches is due to the way that light switch circuits work, and this kit gets around that problem by not using a traditional light switch circuit. Instead, it uses a primary switch, a companion switch, and a plug-in bridge unit that allows them to connect wirelessly.

Cost Savings: By curbing energy use and reducing the frequency of lamp replacement, dimmer switches can lead to substantial savings, making them a financially smart choice for your home. If you already have a smart home, or you’re in the process of setting one up, this smart dimmer switch from Kasa will make an excellent addition. Installation is simplified by detailed interactive instructions in the Kasa app, it works with several smart home ecosystems, and it connects directly to your wireless network so you don’t need to worry about buying and setting up a separate hub. With the phasing out of incandescent lamps, more and more fluorescent lamp manufacturers are making dimmable lamps available. They are at an advanced stage of development and although expensive at this time, it is anticipated that the price will reduce as they become more popular. Dimming LED Lamps Common Uses For Leading Edge Dimmers: Most often used to dim incandescent and mains voltage halogen light bulbs and capsules. Also suitable for dimming most electronic low voltage transformers, including wire-wound or toroidal transformers, and under certain circumstances, constant current dimmable LED drivers. By adding additional Leviton Decora Smart Dimmer Companion switches, you can set up virtual 3-way, 4-way, or even 5-way control over your lights. The primary switch has to be wired to the lights like a traditional dimmer, but the companion switch can be placed anywhere and doesn’t need to be connected to the main switch by physical wires. The connection is achieved wirelessly through your Wi-Fi network, so you do need to have Wi-Fi to use this kit. It works with Alexa, Google Assistant, and Apple HomeKit, so you can also use it to operate and dim your lights through an app on your phone or voice commands.Toggle: These look like standard toggle light switches, but you can raise and lower the toggle to dim and brighten your lights instead of flipping on and off in two binary positions like you would with a traditional light switch. In other cases, the toggle itself acts as an on/off switch, and you adjust the illumination level with a very small slider that’s located right next to the toggle. These are best for applications where you won’t need to adjust the illumination level every day.
