I opted for this light Quiet (s), because I was looking for a way to equip my bedroom behind the bed with indirect lighting. The concept goes full. I have now bought 3 light bars, as these can be linked together. The advantage is the possibility to operate the connected light strips with a power supply. The controls are simple, but the switch for my taste is mounted too close to the power plug. My expectations were fully met. The colors produced are very nice for my taste, and neither too bright nor too dark. However, I wonder why Philips offers the light strips only as Kompletset with power supply. It should surely be possible to offer the bars to expand without power supply.
I would not hesitate to attack again on this product and can not imagine many application examples, which I will perhaps still one or other implement.
Conclusion: + Nice, pleasant light in several color shades + Power efficient as LED + Quiet PSU + Versatile + Easy to assemble - Switch too close to the power plug - No extension set for existing light strips available
