Tradfri White Spectrum Smart Bulb – Bayonet Cap (B22)

Zigbee & Bluetooth enabled, dimmable, smart bulb.

  • PiTV Setup included: If you purchase a PiTV hub we can set this up for you. If you’ve already purchased a PiTV in the past we can set this up too, just add this service to your cart.
  • White Spectrum Colours: Choose from Warm White through to Cold White Colours.
  • Smart Bulb: Switch on, off and control dimming  by voice command, phone app, schedule or by any smart home trigger.
  • Full Home Assistant integration: Control and automate any bulb easily from anywhere. Upgrade bulb software with Zigbee2MQTT.
  • Zigbee Communication: Doesn’t rely on the cloud to function and it isn’t connected to anything on the internet. Functions as a Zigbee router to improve the mesh network coverage.
  • Power on mode: Change the power on mode (on (default)/off/last) with Zigbee2MQTT.
  • Ideal for fitting in bedrooms: Change the power on mode to off and when there’s a power cut you won’t get woken up when the power restores and the bulb switches on. If specified when ordering with a PiTV hub, we’ll do this for you along with pairing.


With a smart LED bulb you can adapt your lighting to different activities, for example a warmer light for dinner and a brighter, colder light for working.
