10 metre extension cable, available in black or white, for our mains voltage connectable lights range. By far the most frequently used accessory in this range & has two main uses: To extend the distance between the plug & the first light Can be inserted between two compatible products For example: if you wish to put lights on two trees, one at the top & one bottom of the garden, but do not want lights running in between. Then you would use the extension cable to carry the power from the lights on the first tree to the lights of the second tree. Multiple extension cables can be connected together to increase length as required.
