I wanted to test the LEDs in a long time, especially the aspect of energy savings and longevity. This kit is dropped to the bottom! And when we start on the Philips, we already know that it will be serious. This was confirmed with the opening of the big box: it's clean, precise finishing and everything and everything. On the employment side, three large bulbs cap, so is simple to install. The bridge must be plugged in, and then retrieves the application that is well on his phone. No quack! I especially like the ability to play on the intensity: a drive by what we do in a room, it's really very nice. It can immediately give a warm atmosphere, cozy, quiet ... What I like also most is the ability to simulate a presence in the house, anytime. Wouaw so that I have still not all the way around, so this system offers solutions !!! It opens a lot of perspectives. It is even quite confusing in the beginning, you get lost a little, which is why I put 4 stars. The fact that we lose control when we use the physical switch is also a pity, but I say that with a little luck, a future update of available apps will correct this ... The major shadow point will in fact necessarily the price, because the kit is 199 euros ... Bulbs sold individually are not yet available, it seems, but I fear the price. Everyone can not afford that kind of investment. ;-)
