Question about Philips Hue White Ambiance Enrave

Does the lamp have a remote control? Or do you have to buy an extra HUE box?

At what temperature (K) does the light provide a brightness of 4300 lm?

Yes, the three suspension cables can be adjusted individually

I haven't done this myself, but it should work. The length of the three wires can be changed individually and even if the ceiling is straight, the lamp must be levelled with a spirit level
