LEDVANCE Smart LEDPanel Luminaire with WiFi Technology for Inside, Tunable White (3000-6500K), RGB Colors Changeable, 450 mm X 450 mm, Compatible with Google and Alexa, Smart+ ORBISPLUS Multicolor

For a smart light this is okay. I've seen way better for less. Since day one of using this I've had problems getting it to work fully with Google Home. It simply doesn't work in the sense that you can't access the full feature set (colouring) via Google Home. Even with their own app (LEDVANCE), its impossible to make this output a white or close to white light. It has two modes, one which normally (on other similar products) should let you adjust the "warmness" from yellow to white. And an RGB Mode. For the natural light mode, it's fixed on a mid yellowish tone and there is seemingly no way to adjust this. This also is the only mode where it provides an acceptable brightness to be called a ceiling light. However I can't make this whiter or make any adjustments to this yone. In the RGB mode, the brightness is easily a 10th that of the natural light mode and is incredibly weak. Not to mention, it's also impossible to get a solid white out of this mode but that may be due to the incredible lack of brightness.

Says these lights are 450 x 450 mm but in description they are 300 x 300 mm. They are not what it seems and are more expensive than the 300 x 300 mm. Someone needs to get this sorted. Very misleading and a waste of my time.
