RGBW colour range and dimming

The TP-Link Tapo L531E is a smart LED bulb that produces 16 million colours and adjustable white tones from 2500K to 6500K. It delivers 800 lumens at a 60-watt equivalent with a colour rendering index above 90. A 220-degree beam angle provides broad light coverage and the bulb dims smoothly from one to one hundred percent.

Best for app-based mood lighting.

This bulb suits anyone who wants voice or phone control over colour scenes, schedules and away-mode simulation via Alexa or Google Home. Real-time energy monitoring helps track consumption. It is not intended for fixtures that require more than 800 lumens or for installations that need a 5-gigahertz Wi-Fi connection.

2.4-gigahertz Wi-Fi only

The L531E connects exclusively to a 2.4-gigahertz network and does not support 5-gigahertz bands. Buyers must confirm their router broadcasts a compatible 2.4-gigahertz SSID before purchase.

Questions about this item

Will the Tapo L531E work on my existing 2.4 GHz Wi-Fi network alongside older smart devices?

Yes, the bulb connects to a 2.4 GHz Wi-Fi network and can be controlled through the Tapo app alongside other compatible devices on the same network.

How can I verify the Tapo L531E is producing the claimed 800 lumens and CRI above 90 after installation?

In the Tapo app you can set the bulb to 100 % brightness and 6500 K colour temperature; the app reports the current output and the specifications list 800 LM and CRI > 90.

Does the L531E package include a hub or bridge, or must I buy one separately?

No separate hub or bridge is required; the bulb connects directly to Wi-Fi and the box contains only the A19 smart bulb itself.
