Smart WiFi Colour Bulb

The TP-Link KL125 is an E26 smart LED bulb that delivers 800 lumens from 9 watts. It connects directly to a secured 2.4 GHz WiFi network using IEEE 802.11b/g/n without a separate hub. The Kasa app for iOS 10 or Android 5.0 and higher handles setup, scheduling and remote control from anywhere. Voice commands work with Amazon Alexa and Google Assistant.

Fits Standard Sockets And Apps

The A19 shape fits common E26 lampholders at 120 volts and 60 hertz. A 220 degree beam angle spreads light widely for general room lighting. No hub hardware is required, freeing a power outlet and simplifying the network. The bulb operates between minus 15 and 40 degrees Celsius and 10 to 90 percent humidity non-condensing. Grouping lets one command control multiple bulbs together.

Replaces Fixed-Colour Bulbs

This unit replaces single-colour or non-dimmable bulbs where adjustable white from 2500 to 6500 kelvin and 16 million colours add value. The jump is worth it when you want app dimming from 1 to 100 percent, away-mode scheduling and voice control without rewiring. It is not for fixtures needing 5 GHz connectivity, higher lumen output or a CRI above 90.

Questions about this item

How long will the bulb last at its maximum 40 °C operating temperature before the LEDs degrade?

The bulb is rated for continuous operation up to 40 °C (104 °F) with 10–90 % non-condensing humidity.

Does the 9 W draw produce noticeable heat or fan noise when left on all day?

The bulb draws 9 W, has no fan, and runs silently; surface warmth is typical for an 800 lm LED.

What must already be in place for the KL125 to connect and be controlled?

A secured 2.4 GHz IEEE 802.11b/g/n Wi-Fi network and a smartphone running iOS 10 or Android 5.0 or higher with the Kasa app.
