What about using your own "darkness" sensor, such as "12V Mini Remote Photocell Dusk To Till Dawn Automatic Light Switching Sensor" eBay £2.95 ?

Not a bad idea

Excellent idea - might have a look at that myself and use one in conjunction with the OP's widget, as mine currently only have an on/off switch.
