Do smart lights need a hub to work?

It depends on the brand. Philips Hue requires a Hue Bridge hub (included in starter kits) for full functionality — without the hub, bulbs are uncontrollable if Wi-Fi goes down and cannot be automated. LIFX bulbs connect directly to Wi-Fi — no hub needed. Kasa bulbs (TP-Link) connect directly to Wi-Fi with no hub. Zigbee-based bulbs (most Hue, IKEA Tradfri) need a Zigbee hub or a smart home controller with Zigbee (Amazon Echo 4th Gen, SmartThings). Wi-Fi bulbs are simpler to set up but add to Wi-Fi network congestion. Zigbee bulbs are more reliable and responsive but require the hub investment.

Are smart bulbs compatible with all light fixtures?

Smart bulbs replace standard A19 (medium screw) bulbs in any fixture that accepts that base. They will not work in enclosed, airtight fixtures (sealed flush mounts) — the heat buildup exceeds the rated temperature and dramatically shortens bulb lifespan. Most smart bulbs specify 'not for use in enclosed fixtures' in the specifications. For recessed cans: smart bulbs work if the can is open on the bottom (most are). For ceiling fan light kits: check that the socket is a standard A19 base — some fan kits use smaller candelabra (E12) bases that require a smaller smart bulb.

What happens to smart lights when the internet goes down?

Most smart lights can still be controlled locally when the internet is down but the home Wi-Fi or hub is working. Direct switch control (turning the physical switch on and off) always works. App control over local Wi-Fi (not requiring internet) works for Hue, LIFX, and Kasa when the controlling device is on the same network. Automations that trigger from cloud services (Google Assistant, Alexa routines) stop working when internet is down. Voice control through a local smart speaker may continue if the speaker has local processing.

Do smart bulbs work with dimmer switches?

Smart bulbs must not be used on wall dimmer switches — they require constant full power. A dimmer switch that reduces voltage causes smart bulbs to flicker, not dim properly, and can damage the bulb's electronics over time. To dim a smart bulb: control dimming through the app or voice command, not the physical switch. Replace any dimmer switch in the circuit with a standard on/off switch before installing smart bulbs.
