Conclusion on TP-Link LB120 LED bulb
We can only recommend the smart LED bulb LB120 from TP-Link to a limited extent. The interaction with the Kasa App allows a not yet completely problem-free control. However, this can be fixed by software updates in the future and during our test TP-Link has already released several updates. We were also convinced by the outstanding colour and light quality, each dimmable as required. Neither an additional hub nor an extra Smart Home control centre is required. Only the price could deter one or the other user a little, because compared to pure LED light bulbs without Smart Home control, this is still relatively high at 40 euros.
