Flip the switch to simulate power out! From a 5v signal like a 5v plugpack... The 12v supply to power the lights can be a lead acid battery... no more total blackouts with my design :)  now regulated at 300ma for leds

Only to 12V lamps or multiple LED's, not 120 or 240V lamps, you'd need an inverter

Yes, from a small 12v battery lead acid, all low voltage, the 5v supply could be usb, or some other adapter... the tricky part seems to be limiting the current from the 5v supply

No need for current limitation, let it draw current till it blows :D haha
