Questions about Philips Hue Centris Base BT

"Light bulb replacement"? There are LEDs in there and I think they are permanently installed and will last a lifetime.

The base in the name makes no sense, the BT only means that the lamp supports Bluetooth (without Hue Bridge) in addition to ZigBee (connecting with the Hue Bridge).

Yes, depending on the position of the neighbouring spots.

Yes, there are really 5 lamps that you can control.

Hello Majins, To answer your question I have one personally. The colour of each light is individually adjustable and you can create custom scenarios. Honestly I find this light really top of the line technology today. It's easy to use and the application is very fluid.

16 million colours& cold, warm, natural white is right

The three spots and the "bar" can be controlled separately with the app (colour/dim/switch off/on). I can "programme" the dimmer switch in a limited way via the app, but I do entire zones with several lamps with the Hue Bridge and don't want to control individual spots/beams. The individual lamps can be given different names in the app and can thus also be controlled individually.
