Kasa Smart KL125P4 A19 Smart Wi-Fi LED Bulbs, Multicolour, 800 Lumens, 4-Pack

A19-format LED bulbs with E26 bases, this four-pack adds smart, multicolour lighting to compatible indoor fixtures. Choose from 16 million colours or tune the white light from warm to cool, then adjust brightness through the Kasa Smart app or with voice control. Each bulb uses 9 W and provides up to 800 lumens, giving you flexible lighting for everyday routines and different room settings.

Connect the bulbs to a 2.4 GHz Wi-Fi network to control them without a separate hub. Set lighting to suit a quiet evening, a gaming session or a get-together, and use schedules to make everyday adjustments automatic.

Pros

Colour and dimming controls make it easy to change a room’s feel without changing bulbs. Pick a colour for a gathering, switch to warm or cool white for daily use, or lower the brightness for a softer evening setting. The Auto White feature can adjust colour temperature through the day, while scheduling lets you set regular on-and-off times. With four bulbs in the pack, you can coordinate lighting across several fixtures rather than set up one room at a time.

Control is available through the Kasa Smart app, including remote on/off, dimming and colour changes. amazon Alexa and Google Assistant voice control adds a hands-free option when you’re coming into a dark room or have your hands full. Energy monitoring provides a way to view real-time energy use, and Away Mode can switch the lights on and off at random when you’re away.

Buyers commonly highlight the broad colour selection and straightforward setup, and some appreciate how easily brightness and colour can be changed. Feedback on connectivity, reliability and brightness is mixed, so experiences differ. White settings provide up to 800 lumens, the brightness may feel different when using colour modes.

Worth noting

These are indoor A19 bulbs with E26 bases, designed for a 2.4 GHz Wi-Fi connection. The listed white colour temperature range is 2500K to 6500K, spanning warm through cool white. They’re a practical choice when you want app and voice control, colour options and scheduling in one lighting setup, rather than basic bulbs controlled only at the wall. The four-pack includes four Kasa Smart multicolour bulbs and a user manual.

Tips for day-to-day use

Use a standard, non-dimmable light switch, adjust brightness through the Kasa Smart app instead of pairing these bulbs with a dimmer switch. Once connected, set schedules for regular routines or use voice commands with Alexa or Google Assistant. For a simple daily pattern, Auto White can shift the colour temperature from dawn to dusk, while manual colour and brightness controls let you change the scene when plans call for it.

Practical questions

Do these bulbs need a hub? No separate hub is required. They connect directly to a 2.4 GHz Wi-Fi network for app control and automation.

Can I control them with Alexa or Google Assistant? Yes. The bulbs support voice control through Amazon Alexa and Google Assistant, as well as control in the Kasa Smart app.

Can I dim them with a wall dimmer? Use a non-dimmable light switch. Brightness adjustment is available through the Kasa Smart app.

When it makes sense

A solid pick if you want to update several indoor fixtures with adjustable colour, tunable white light and app-based routines. The four-bulb pack suits rooms where lighting needs to shift between everyday tasks and different moods, while voice control and scheduling make those changes easier to manage.
