What Is Smart Lighting?
Smart lighting refers to light bulbs, switches, and plugs that connect to your home Wi-Fi network and can be controlled remotely. There are two main approaches:
- Smart bulbs: You replace your existing light bulbs with smart bulbs. The bulb itself contains the Wi-Fi radio. You keep your existing light switches, but the switch must stay in the ON position for the smart bulb to work. Control is done through an app or voice assistant.
- Smart switches: You replace your existing light switches with smart switches. Any regular bulb in that fixture becomes controllable. Smart switches work with the physical switch AND the app, which is more natural for most households.
Tip: Smart switches are generally the better long-term choice for most rooms because they work like normal switches — anyone in the household can use them without needing an app. Smart bulbs are better for lamps and fixtures where you want color-changing or dimming features.
What You Can Do with Smart Lighting
Here are the features homeowners find most useful.
- Remote control: Turn lights on or off from your phone, even when you are away from home
- Schedules: Set lights to turn on at sunset and off at bedtime automatically
- Dimming: Adjust brightness from your phone or with a voice command — no dimmer switch required for smart bulbs
- Color changing: Some smart bulbs (like Philips Hue) can display millions of colors — useful for ambiance or holiday decorating
- Voice control: "Alexa, turn off the living room lights" or "Hey Google, dim the bedroom to 30 percent"
- Away mode: Randomly turn lights on and off while you are on vacation to make the house look occupied
- Routines: Set up automations like "turn on the porch light at sunset and off at 11 PM every day"
Popular Smart Lighting Brands
These are the brands homeowners ask us about most often.
- Philips Hue: The most popular smart lighting system. Excellent app, wide product range (bulbs, light strips, outdoor lights), and works with Alexa, Google Home, and Apple HomeKit. Requires a Hue Bridge hub for full features, though newer bulbs also work without one.
- Kasa Smart (TP-Link): Affordable and reliable. No hub required. Works with Alexa and Google Home. A great choice for beginners who want simple on/off and scheduling without color features.
- LIFX: No hub required, excellent color quality. More expensive than Kasa but simpler setup than Philips Hue.
- GE Cync: Budget-friendly option that works with Alexa and Google Home. Good for basic smart lighting without a large investment.
- Lutron Caseta: The best smart switch system. Extremely reliable, works with all major voice assistants, and does not require a neutral wire (which many older homes lack).
Setting Up Smart Bulbs
Smart bulbs are the easiest way to get started with smart lighting.
- 1Screw the smart bulb into your existing light fixture
- 2Make sure the wall switch for that fixture is in the ON position
- 3Download the app for your smart bulb brand (Philips Hue, Kasa, LIFX, etc.)
- 4Create an account or sign in
- 5Follow the in-app setup wizard to connect the bulb to your Wi-Fi network
- 6Name the bulb by room (Kitchen, Living Room, Bedroom) for easy voice control
- 7Test it by turning it on and off from the app
Warning: Smart bulbs need the wall switch to stay ON at all times. If someone turns off the wall switch, the bulb loses power and cannot be controlled by the app or voice commands. Consider putting a small reminder sticker on the switch, or replacing the switch with a smart switch that sends a signal instead of cutting power.
Setting Up Smart Switches
Smart switches replace your existing wall switches and require some basic electrical work. If you are not comfortable working with electrical wiring, a technician can install them for you.
- Most smart switches require a neutral wire — a white wire in the electrical box. Many older homes have this, but some do not. Lutron Caseta is a popular option that does not require a neutral wire.
- Turn off the power at the circuit breaker before touching any wires
- Remove the existing switch and connect the smart switch wires according to the included instructions
- Restore power and follow the app setup to connect the switch to your Wi-Fi network
- Once set up, the switch works both physically (press it like a normal switch) and through the app
Connecting Smart Lights to Alexa or Google Home
Once your smart lights are set up in their own app, you can connect them to Alexa or Google Home for voice control.
- 1In the Alexa app or Google Home app, tap the plus (+) button to add a device
- 2Select the brand of your smart lights (Philips Hue, Kasa, LIFX, etc.)
- 3Follow the instructions to link your account
- 4The voice assistant will discover all your lights automatically
- 5You can then control them by voice: "Alexa, turn on the kitchen lights" or "Hey Google, dim the bedroom to 50 percent"
