Incredible purchase... I didn't expect it to do all that... I don't care about the energy label (F)... My favorite menu is Scene where I use, for example, the soft setting in the morning at 05:30 a.m., another scene at night or at noon on a cloudy day, another for movies, etc. It was installed on the ceiling and in a random spot in the center of the open-plan living room-kitchen and small entrance hall (50 sq.m.) and is now used as the main lighting, especially at full cool white brightness (3600LM)... it's like day!!! Even with daylight, if I turn it on, there's still a big difference.... Note regarding connectivity: if it stays on red light, it hasn't connected to the wi-fi (red, as in Music Sync, when the phone doesn't pick up sound). The instructions also mention how to reset it, e.g., by switching the light switch ON-OFF 3 times, etc. The other color palettes don't interest me personally, they were just tested for fun... Either way, my choice was very good in terms of money and performance. Its durability will show in the future, but even if it 'burns out,' I'll get the same one again, maybe in the larger size (3 sizes).
