Should I use smart switches or smart lights?
The choice turns on two questions: how many bulbs sit behind the switch, and whether you want more than on, off and dim. Plenty of homes end up using both.

The quick answer: Our pick for lamps, rentals and any room where you want color or tunable white is smart lights, specifically LIFX Wi-Fi bulbs: they screw into existing fittings and connect straight to Wi-Fi, with no hub, and the Everyday bulb lists Matter support. The LIFX Everyday Smart Light 2-Pack costs $19.98. Choose a smart switch when one switch runs several bulbs or guests rely on the wall. LIFX's Smart Dimmer ($34.98) needs a neutral wire, so Lutron Caséta, which also makes no-neutral dimmers, suits switch boxes without one.
What actually decides it
- Bulbs per switch. A single lamp needs one smart bulb. A kitchen with six ceiling lights on one switch needs six bulbs, or one switch.
- What you want the light to do. A switch or dimmer changes power and brightness. A color bulb also changes color and white temperature; LIFX lists 2700K to 6500K for its Everyday bulb.
- Who uses the wall. A smart bulb needs power to respond, so the wall switch has to stay on. If guests or children flip switches, bulbs alone can frustrate everyone.
- Your wiring and lease. Smart switches are hardwired. The LIFX Smart Dimmer requires a neutral wire, and renters usually cannot replace switches without permission.

Where LIFX fits — and where it doesn't
Choose LIFX bulbs when you want color, tunable white or lamp control without changing any wiring. LIFX says its bulbs fit A19, A21, BR30, T10 and candelabra fittings and set up in the app with no hub. The Everyday bulb lists 800 lumens, a color rendering index of 90 and Matter support, so it can join major voice assistants and Matter platforms.
Choose the LIFX Smart Dimmer when a switch runs several ordinary bulbs and you have a neutral wire. LIFX says it works with regular dimmable bulbs out of the box, keeps working as a dimmer if Wi-Fi drops, and offers four buttons with three press types, up to 12 programmable actions. Paired with LIFX bulbs, the same switch can call up scenes and colors. It handles up to 300W of LED load and is Matter certified.
Consider Lutron Caséta instead when your switch boxes lack a neutral. Lutron makes neutral and no-neutral dimmers, and a Pico remote adds a second control point without new wiring. Voice control requires its smart hub, which Caséta starter kits include.
Consider Philips Hue instead when you want a large bulb system with a dedicated hub. Hue bulbs work over Bluetooth for small setups, while a Hue Bridge supports up to 50 lights and 12 accessories, and Hue accessories can pair with bulbs directly.
Where LIFX bulbs are not the best fit: many fixtures on one switch cost more in bulbs than one dimmer, and LIFX's dimmer is neither renter-friendly nor an option without a neutral wire.
A worked example: one living room
Illustrative room: a four-bulb ceiling fixture on one switch, plus one floor lamp. Prices are lifx.com listings; tax, shipping and any electrician are excluded.
- Smart lights only: five LIFX Everyday bulbs means three 2-packs: 3 × $19.98 = $59.94, with one spare. You get color everywhere, but the wall switch must stay on.
- Smart switch plus one bulb: a LIFX Smart Dimmer for the fixture and one 2-pack for the lamp: $34.98 + $19.98 = $54.96. The fixture keeps its dimmable bulbs and dims from the wall.
- Both: the dimmer, four SuperColor 800-lumen bulbs for the fixture (4 × $19.44 = $77.76) and a 2-pack for the lamp: $34.98 + $77.76 + $19.98 = $132.72. LIFX says the dimmer controls SuperColor bulbs' colors and scenes, and guests still get a wall switch.
Checklist before you decide
- Count bulbs per switch. Three or more bulbs on one switch usually tips the math toward a switch.
- Open the switch box, safely. Confirm whether a neutral wire is present before buying a neutral-only dimmer; cut power at the breaker first.
- Check your Wi-Fi band. LIFX bulbs and the Smart Dimmer use 2.4GHz Wi-Fi.
- Check the load. The LIFX Smart Dimmer handles up to 300W of LED lighting.
- Plan for guests. If others use the wall switch, pair bulbs with a smart switch or remote.
- Read your lease. Replacing a switch can require landlord permission; bulbs come with you when you move.
Common questions
Will a smart switch work with the bulbs I already have?
Usually, if they are dimmable. LIFX says its Smart Dimmer works with regular dimmable bulbs, and Lutron lists Caséta dimmers for dimmable LED and incandescent or halogen bulbs. Check the load limits first.
Do LIFX bulbs need a hub?
No. LIFX says its bulbs connect directly to home Wi-Fi, and the Everyday bulb lists Matter support for use with other platforms.
Is a smart switch cheaper than smart bulbs?
It depends on the bulb count. In our example, one dimmer and a 2-pack cost less than five bulbs, while a single lamp is cheapest with one bulb.
Take this with you: Use bulbs where you want color or cannot rewire, use a switch where many bulbs share one switch, and combine them where guests need a wall control.
Next step: Count the bulbs on each switch you want to upgrade, then compare the specs and wiring notes on LIFX's Smart Dimmer page against your switch box before choosing bulbs, a switch or both.
