Four-pack multicolor smart bulbs

This pack contains four A19 LED bulbs that connect directly to a 2.4GHz Wi-Fi network using the IEEE 802.11b/g/n standard. Each unit draws 9W while delivering 800lm of tunable white light from 2500K to 6500K plus 16 million colours. Control is handled through the Kasa app on iOS 10 or Android 5.0 and above, with no separate hub required.

Households wanting voice and remote lighting

The bulbs suit anyone who wants Alexa or Google Assistant voice control, scheduling, away-mode simulation and real-time energy monitoring from a smartphone. They are not for installations that only have 5GHz Wi-Fi, for fixtures that need a higher lumen output, or for buyers who prefer local-only control without cloud connectivity.

2.4GHz Wi-Fi only connectivity

The single specification that decides compatibility is the 2.4GHz frequency requirement; the bulbs will not join a 5GHz-only network. A secured home Wi-Fi connection on the 2.4GHz band is mandatory for setup and ongoing operation.

Questions about this item

How can I verify the bulb is working correctly after connecting it to my 2.4GHz Wi-Fi network?

Open the Kasa app on a device running iOS 10 or Android 5.0 or higher; the bulb should appear online, respond to on/off commands, dim smoothly, and cycle through the full 16 million colour range.

What comes in the box and is any extra hardware needed for setup?

The pack contains four A19 multicolour smart bulbs and a quick start guide; no separate hub or bridge is required because each bulb connects directly to a secured 2.4GHz Wi-Fi network.

Which version should I choose if I want 60 W equivalent brightness with full colour control?

This 4-pack delivers 800 lumens at 9 W per bulb, matching a traditional 60 W incandescent while providing tunable white from 2500 K to 6500 K and full RGB colour changing via the app.
