Perhaps the time is now right to replace domestic lighting circuits with 12V supply, then the cost of the fitments will come down, ie no need for 110/240V conversion to low dc for the leds. Safer, cheaper, more reliable, less raw materials. At those power levels, you could probably keep the original house wiring and just fit a 12V transformer/rectifier. Easier to use alternative power sources, too.
Be nice if we had your prices over here.
