In the uk is it ok for an outdoor floodlight to be plugged into a typical indoor socket ? or does it have to be wired into the house circuit ?

or does it have to be wired into the house circuit ?

Answers: That's ok, most outdoor floodlights hold a maximum power of 500W, which draws 2 Amps of current. Your plugs in your house can hold 13 Amp fuses, so don't worry something like it, just plug it contained by.
