Power cable can be retracted at any time when mounted. The luminaire can also be easily adjusted in height with the 3 ropes.

Hello Samibell The only difference is that the version with the "BT" is equipped with Bluetooth. You can control the version with "BT" (if you don't have a Hue Bridge) via your smartphone. If you buy the version without the "BT" you have to buy a Hue Bridge to control it via your smartphone, because the communication works via Zigbee.

It won't work with a hook. It has a small bracket which is to be screwed to the ceiling.

They appear to be the same two products, but they do not have the same supplier.

Hello Anonymous Unfortunately I can't help you with your problem. I have the same lamp hanging in my living room and I hear absolutely nothing. My previous lamp, a completely different model and make, also had an annoying buzzing, my electrician said that this could be connected to the transformer, we replaced it and for a while it was quiet but then the whole thing started all over again.

The Hue Amaze can be dimmed, switched on/off or assigned a scene with the app like other Hue lamps. However, pairing/connection with the Hue Bridge is mandatory. Note: The included remote control can also be configured with the app and used with other Hue lamps and groups through the bridge. Note for pairing with the Hue Bridge: Before mounting the lamp, always note the hardware/serial number of the lamp on the base in case the automatic pairing with the Bridge does not work right away.
