I think you'd need to go the 12v transformer route as Dobbie said. You could use DC plugs or solder the transformer to the led strip light and then heat shrink it so its a permanent connection like its a pre made one....
Thanx for the ideas everyone. In the end ive gone for a rechargeable 500 lumin LED wand from Bunnings that plugs into 240v outlet. It fomes witn a stand, hanging hooks and is magnetic so you can also use that to hang/hold it onto metal bits too
