Do smart bulbs work without Wi-Fi?

Most Wi-Fi smart bulbs require a constant Wi-Fi connection for app control, schedules, and voice assistants. However, manual switching (from the physical light switch) still works — the bulb just turns to its last state. Some systems (Philips Hue with Bridge) maintain local control on your network even if internet goes down. Zigbee and Thread bulbs only need the local hub/border router to function.

Will smart bulbs work with regular light switches?

Smart bulbs need power to receive commands — turning off the wall switch cuts power and makes the bulb unresponsive to app/voice. Solutions: leave wall switches always on and use the app/voice/smart switches to control, or replace wall switches with smart dimmers that cut smart bulb power intelligently. Philips Hue offers Hue Dimmer Switches as wireless overlays that don't cut power.

Can I use smart bulbs in any fixture?

Standard A19 smart bulbs fit any E26 standard US base. Some fixtures have enclosed globes or recessed cans that trap heat — check if the smart bulb is rated for enclosed fixtures. LED smart bulbs run cool, but confined air spaces can shorten bulb life. Many manufacturers label their bulbs as 'enclosed fixture rated.'

What's the difference between color temperature and full color?

Color temperature (warm white to cool daylight, measured in Kelvin) lets you go from cozy 2700K (candlelight) to focused 5000K (bright daylight) — useful for productivity and relaxation. Full RGBWW color adds the ability to show any color (red, blue, green, pink, etc.) for accent and mood lighting. Most premium smart bulbs include both: adjustable white temperature AND full RGBWW.

Are smart bulbs expensive to run?

No — LED smart bulbs typically draw 8-11W at full brightness vs 60W for incandescent equivalents (85% energy savings). A bulb running 8 hours/day costs roughly $2-4/year in electricity. The standby power draw (to maintain Wi-Fi connection) is 0.3-0.5W — about $0.50/year extra vs a dumb LED. The efficiency savings overwhelmingly outweigh the standby cost.
