Does this bulb need a hub?

No — Kasa Smart Bulbs connect directly to your home Wi-Fi (2.4 GHz only), so no extra hub is required. Use the Kasa Smart app to control and create scenes.

Can I control the bulb with Alexa and Google Assistant?

Yes — after you add the bulb in the Kasa app, link your Kasa account inside the Alexa or Google Home app and discover devices. Then use voice commands like “Alexa, set kitchen light to 50%” or “Hey Google, set bedroom light to blue.”

What is the difference between multicolor and tunable white bulbs?

Multicolor bulbs let you select any RGB color plus tune white; tunable white bulbs let you adjust color temperature between warm and cool white (2500K–6500K) but do not provide full RGB colors. Choose multicolor for decorative lighting and tunable white for flexible white/ambient lighting.
