What is LED? LED Durawise is the new LED battery-operated lighting that can be used both indoors and out. It does not need any cable. Plugs and extension cords are done away with. LED Durawise also has a timer function to allow the lighting to be switched on automatically for six hours a day. With just a single button press, the light will be set to switch on at exactly the same moment each day for no less than 30 days! Ideal in all seasons - not least for cosiness around Christmas and New Year, or long summer evenings in the garden.
