First had to fumble a bit until the cable was installed behind the drywall. A hole the size of a cavity socket you should ever not for the small lamps drill :-) The lamp itself is but then quickly installed. It is based on a U-shaped elbow with two oblong holes. This small inaccuracies when drilling or when setting the hollow wall anchors can be corrected yet. The transformer is connected via enclosed terminal strips, the lamp then hooked into the top corner and bolted. The ring can be relatively free to rotate or Schwenke. (Actually, of course, but I mention it anyway:.! That's not really a radiator or Spot One should not expect a directional cone of light)
The lamp has a small switch on the housing. You are a pleasant and relatively bright light it will not affect cold. If you sit close to the lamp, it is to read definitely bright enough. In the single as well as in the off state can the individual LEDs behind the wheels not matter. Only shortly after being switched off when the afterglow LEDs, one realizes the arrangement. Whether they will be very hot, I honestly have not tried after installation I have not been sitting in the guest room to read.
Conclusion: Small, discreet, sends. Does not everyone. And they are also a nice light.
