Once received, once installed. And I am excited !!! I had to connect all 3 minutes (two sockets to plug the wall) and synchronize it with my small case box (connect the cable box to the back of my box and install Philips Hue on my smartphone via Google Play). Then I had fun choosing the colors, save themes with colorful mood for any time of the day. My living room is red, gray and black, I have chosen one of two lamps of red light. (I put two photos where I connected the two lamps in my living room for the photo). And I plugged the other into my room with another color. The atmosphere is simply magical. Sometimes mellow, sometimes hot, sometimes subdued, sometimes full lights. I drive the whole distance with my smartphone. It's a breeze !!! And my children, however, find it "too coooooool !!!". I admit that if it were not so expensive, I will offer me many other lamps ... Go, Philips, a little effort on the price ... your blooms are simply great!
