No it&#x27;s absolutely not what someone would do, but it is what the grandparent proposed, that&#x27;s why I addressed it.  I&#x27;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&#x27;ll have more freedom on the sockets and interfaces.<p>As far as other devices needing the AC power, you&#x27;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&#x27;ll still have the AC running through the house for a very long time anyway, so you&#x27;ll end up with nothing changing.
