Last night at a client’s home we were given a quick display of their lighting system. Wow! They have the Philips Hue personal wireless lighting. I’m still wrapping my head around this system but essentially you can turn on, turn off, and dim any lamp next to you or half a world away. You can also choose the shade of white from warm to cool. With the colour bulb you can choose different colours. You can also program your lights to turn on or off at a specified time. You can watch a video here.
You need a started kit which is available at different sources at different prices. Then you acquire lightbulds as you wish.
