Each Starter Kit includes 2-21" LED strips, a wall transformer and two linking cables (3" and 6"). The Infinilux StripLED lighting systems take advantage of a wide range of technologies to bring you the simplest most effective, low-profile LED lighting system in existence! Ultra Thin, under 2mm (0.080") thick, flexible light strips with high-intensity PLCC-4 LEDs spaced 0.5" on center provide sufficient light for counter height work surfaces when mounted under cabinets. Simple peel-and-stick mounting and plug-and-play wiring make set up a snap. 18 feet of continuous high-intensity lighting can be powered from a single low-voltage wall transformer. Standard 21" strips can be easily trimmed in 3 1/4" increments to fit custom applications with a tailored fit. Over 50% energy cost savings over Mini-Florescent tubes and near 80% cost savings over Halogen systems.
