The UL listed 32 foot add on kit of RGB led cove lights come with everything you will need to extend the length of your cove lights. You will receive two each 16 foot section of RGB tape lights, one indoor RGB repeater and one 24 volt 432 watt power supply. The tape light cove lights dimensions are .53 inches wide by .27 inches tall by 16.4 feet long. The cove lights can be cut every 4 inches. The cove lights consume 4.4 watts of electricity per foot and product 360 lumens of light per foot. To install these lights there is some minor wiring you might have to do between the power supply and the lights so we suggest you have some low voltage wire along with the crimping electrical connectors or wire nuts on hand. Please note this is a hard wire power supply.
