Installation Steps
Replace Your Existing Bulb with the KL110
Ensure the lamp or fixture is turned off at the wall switch. Screw in the KL110 into a standard E26 medium base socket. The KL110 is designed for use with a standard on-off wall switch — do not install it in a fixture controlled by a dimmer switch, as dimmers interfere with the bulb's internal power supply and cause flickering, random resets, and premature failure.
Turn On the Wall Switch and Enter Pairing Mode
Turn the wall switch on. The KL110 will blink slowly to indicate it is in setup mode. If the bulb does not blink, it may already be paired to another account. Perform a factory reset by toggling the wall switch off and on 5 times in quick succession — off 1 second, on 1 second — until the bulb blinks 3 times confirming a reset. The bulb is ready for pairing when it blinks slowly and steadily.
Add the Bulb in the Kasa Smart App
Download the Kasa Smart app and sign in or create a TP-Link account. Ensure your phone is on your 2.4GHz WiFi network. Tap the plus icon then Add Device and select Bulb from the categories. The app will search for KL110 devices in pairing mode. When the bulb appears, tap it. The app will connect to the bulb's temporary hotspot and transfer your home WiFi credentials.
Complete WiFi Setup
Enter your 2.4GHz WiFi password when prompted. The bulb will leave its temporary hotspot, join your home network, and your phone will reconnect to your home WiFi automatically. The app will confirm success with a pairing complete screen. The bulb's LED will stop blinking and glow steadily at its last set brightness level.
