So in my kitchen we have recessed pot lights. Eight of them, 75 watts each. That's 600 watts. They were on a dimmer rated for 500 watts. There are four switches for these lights, two of them don't work, the wiring is screwed up. I've tried desperately to correct it, but a professional electrician friend of mine came and couldn't figure it out, either.
Today I replaces all the light bulbs with Osram Lightify LEDs and created a gateway network for them with a cube. Then I installed four switches also from the Lightify family. They install right over the existing switches, both decorative and traditional. In 30 minutes I switched from a screwed system to perfectly functioning, dimmable, lights and I have the ability to alter their colour from cool to warm. Running only 96 watts. Wiring/switches/dimmers totally adequate, no rewiring or guess work required.
I'm pretty impressed. Can also control it from my phone, which isn't an essential thing, but I can put these things in all the rooms of the house and create separate switches so I can control the whole house. Now I can turn off the bloody lights in my kids rooms from wherever...
I approve of these lighting systems. Helped fix a fairly big pain in the butt in my kitchen.
