The device is processed solid and acts wertig - quite unlike most alternatives from the hardware store. In active ("On") state, a small blue LED. The function turns out without problems. By means of a small switch to choose whether a dimmable lamp is connected or not. The full potential can of course only in the former case exploit (eg slow dimming down when you turn off). Unfortunately you can not directly connected lamp use the adapter (this has no extra-function switch, the operation is only possible with a remote control) - to rely so you are in any case on the FB - so a 1/2 star deduction.
According to my Energiemessgerär the adapter consumes no measurable power in standby (according to instructions
The price is relatively high in my opinion, but given the interested barely adequate. That's why another 1/2 star deduction.
A small disadvantage perhaps: All connected lamps / adapters are in turn individually (or all together or a certain "set", as far as a preset abgespeichtert) driven. This can sometimes be a bit annoying when a larger number is connected to lamps. The active lamp flashes rapidly.
Allegedly, this adapter is also home to the new generation of Philips lamps ("Iris") compatible. In addition, he is - like the other current Living Colors products with the new Philips Hue system (control of the lamps via Bridge and WLAN or iOS / Android app) be compatible - tested I do not have even that, however.
