I am looking at lighting options for my new flat. I'm looking for any recommendations and suggestions for the components to power and control the LEDs.

If we consider the main room (i.e. the open plan living/dining room/kitchen), my idea is to have a number of sets of lights, e.g. the dining area, the area around the TV, the kitchen, and another set of "ambient" lights.

I would like to have just one set of switches/dimmers in a single location along with a transformer and a multichannel driver (or a set of drivers), with the 12/24v line from the driver going to each set of lights (instead of the 240v mains going to all the lights).

I've googled about quite a bit, but ended up with more questions than answers. I've seen DALI and DMX512 based controllers, as well as some "raw circuitboards" if you like, but considering they don't have reviews like most consumer products, I don't really know what is good and what is not. So do you guys have any experience with or suggestions on which drivers might be a good idea?

Also, I would like to know if it is a good idea to run 12/24v wiring instead of 240v.

I would prefer to keep to drivers that use non-proprietary standards so I have the option of controlling the driver over zigbee or green phy.

"The rule of thumb is higher than 100Hz frequency PWM make human can not see the flickering." neuroelec.com/2011/03/high-pwm-frequency-for-led-good-or-bad Some will still see strobing if they move their fingers back and forth past the light source. That can be disturbing. For a major installation, I'd look into non-pwm vairiable DC supplies. –  Wayfaring Stranger Apr 7 '13 at 17:58
    
I've seen a few systems, and I couldn't really see any flickering with PWM dimmers. With voltage dimmers though, I could definitely see the colour change, so I wasn't too keen on them. –  Iyaam Iyaam Apr 8 '13 at 20:48
    
In general lower voltage is safer, and individual wires to each bank of LEDs means one failure wont ruin the whole system –  Eric Fossum Apr 12 '13 at 16:56
