One bulb. Every white. The TP-Link Smart Wi-Fi LED Bulb Tunable White is the smart bulb that replaces the fixed light of a standard LED with an adjustable spectrum from 2700K warm white to 6500K cool daylight — the full range of white light in a single E27 bulb, controlled from a phone, a schedule, or a voice command to Alexa or Google Assistant, with no hub, bridge, or additional hardware required.
Tunable white is the feature that standard smart bulbs — including fixed warm-white or fixed daylight smart bulbs — cannot provide. A fixed bulb is always the same colour temperature: always 2700K warm, always 4000K neutral, always 6500K cool. The tunable white bulb adjusts. At 2700K, the light is warm amber-tinted white — the cosy, relaxing tone of a traditional incandescent bulb, ideal for bedrooms, living rooms at evening, and nighttime wind-down. At 6500K, the light is crisp cool white with a slight blue-white cast — the clear, energising tone of natural daylight, ideal for kitchens, home offices, reading, and task work. Every point between 2700K and 6500K is accessible in the app, allowing the light to be set precisely for the activity and the time of day.
Dimming from 1% to 100% adds a second dimension of control — the light can be warm and dim for a bedroom at 10pm, warm and full for a living room at 7pm, cool and full for a kitchen at 8am, or cool and dim for a night light. The combination of tunable colour temperature and full dimming range means this single bulb can perform the lighting role of multiple fixed-colour smart bulbs.
Control via the Kasa or Tapo app from any phone. Set schedules to turn on and off at specific times. Use sunrise and sunset mode to automatically match the bulb's on/off times to the local UAE daylight schedule — the light comes on as it gets dark and turns off at sunrise. Away mode randomly toggles the light on and off to simulate occupancy when the home is empty. Voice control via Amazon Alexa and Google Assistant handles on/off, brightness, and colour temperature by voice command.
