These extension cables are designed to be used to extend the distance between your Adjustable White Ultra-Thin Recessed Light and it's driver. They are available in 2 foot, 5 foot, 10 foot, 25 foot and 50 foot lengths. They have attached connectors designed to work with the connectors on your Adjustable White Ultra-Thin lights. This makes installation a breeze requiring no wire cutting and splicing. Multiple cables may not be connected together to make longer lengths. These cables are sized appropriately for each length and should not be used for longer distances than they are rated for.
