You need the bridge here in any case. These lamps cannot be operated without it.
You can then connect the bridge to google home and use it for voice control.

I find it regrettable that these lamps cannot be used without a wireless bells and whistles. Is it really so difficult to offer basic functions that can be controlled on the lamp itself, such as indirect lighting in individual colours as well as colour intervals, in addition to an extension option and operation via mobile devices? If this is available in comparable quality and design, I would be grateful for a hint.
