No it's absolutely not what someone would do, but it is what the grandparent proposed, that's why I addressed it. I'd love to see it used for more efficient lighting, as if it was done correctly I think you could get some pretty nicely efficient and long lasting lights that way with a bigger better current driver for the leds. This might be a good idea to move Track lighting to since they'll have more freedom on the sockets and interfaces. As far as other devices needing the AC power, you've got hair dryers, kettles, vacuum cleaners, air conditioners, water pumps, etc that all need more power than would be reasonable with low voltage DC (some might need 25-50 amps to run at the same power they currently use). All of that just means you'll still have the AC running through the house for a very long time anyway, so you'll end up with nothing changing.
