Installation is extremely easy, simply pinch naked wire - finished. The remote control works immediately without any further action and has an amazingly good reception. Even from the next room, the light can even turn on and off. Even in continuous operation the machine is not warm, I conclude on a low additional energy consumption. Only the dimming curve is suboptimal: The LEDs are coming relatively slow light of the darkest setting forth from a certain brightness to go relatively quickly to the maximum. In operation of the switch-off button, the set brightness is saved.
