Do smart bulbs work with regular light switches?

Yes, but with a caveat: if you turn off the wall switch, the smart bulb loses power and can't respond to voice or app commands. Smart switches or switch covers that keep power flowing are the best solution for homes that mix smart and manual control.

How many smart bulbs can Alexa control?

Alexa supports hundreds of smart devices. The practical limit depends on your WiFi network (for WiFi bulbs) or your hub capacity (for Zigbee bulbs). Most home WiFi routers handle 20-30 connected devices comfortably.
