Questions about Philips Hue Fugato Base BT

Can the lamps be set individually, e.g. in terms of colour, or do they all light up in the same way?

do I absolutely need the hue Bridge for this product ? or does the hue dimmer switch 2021 also work without the hue Bridge ? and does this product need a dimmer or can I just use it with a normal light switch in the room? light switch in the room ?

Can I mount this lamp in the bathroom?

Does this lamp come with a dimmer switch like the Hue Runner base bt or do you have to buy it separately?

Can the Philips Hue BT products also be linked with the Hue Bridge? I already have a Philips Hue lamp as a dining room lamp and paired with the Hue Bridge, but I don't want to buy a BT lamp if I then need a second app again.

Can the colour (RGB) of each bulb/spot be changed individually on this model or is the setting global?

I would like to know if the bulbs on this product are only white or if they are white and colour bulbs?
