First of all, let me say this light looks amazing in the home – not only when it's illuminated, but also aesthetically pleasing to look at even when it's switched off. My wife also loves it! We bought this to replace a modular bay fixture that housed 4 × 50W Halogen bulbs. And it looks so much better! It's yet another great product from the Philips Hue range of home automation lights. They also include a Philips Hue Dimmer Switch which is nice.
However, forget it if you think you can install it on your own! The wiring and screwing of the ceiling plate is fairly straight forward. But it definitely needs two people to complete the task – one person to hold the main light cover in place over the ceiling plate, while another person attends to the side screws. I'm really surprised Philips decided not to use slide-and-lock groves for the side screws instead – otherwise I could have installed it on my own.
Connecting the light to the Philips Hue system was simple enough, but… It's really important to record the serial number before installing the light, as this was needed for my Philips Hue Bridge to find it as a new light. Now I can control it using my iPhone, and even tell Siri to turn it on and off… Much to the amazement of my wife (and house guests). I also have it configured on the Hue Dimmer Switch to switch on at 100% brightness in daylight colour temperature (after sunrise), and 65% brightness in night-time colour temperature (after sunset). And it's perfectly bright enough! I would say at 100% brightness it's equivalent to approx 200 watts of light (2,200 lumens), and yet only uses 40 watts of power.
The only drawbacks is that as with most of the Philips Hue lights it's quite pricey, the install was a bit challenging, and the LED light-strip inside the light panel is non-replaceable – however, it is rated up to 30,000 hours.
It's important to note – this light works best as part of the Philips Hue home automation system. You can use the light on it's own via an electrical switch as long as it's not wired up to a physical dimmer, but you won't be able to access the range of colour temperatures (2200K-6500K) or dimming control features which is otherwise best controlled via home automation software.
