The Kichler Lighting 12383WH Class 2 24V 30W Plug-In Power Supply is a component of the Design Pro Linear LED lighting application. All other components are sold separately. The 12383WH allows power to your linear LED system while maintaining portability. An interconnect cable transition module (sold separately) is needed to power LED linear system. Now, with Design Pro LED Linear, Kichler offers you the most flexible, easy-to-install and ultra-thin profile fixture – allowing you to put light anywhere you want it. Under a bed, inside a bookcase, over a cabinet, around a cove: the remarkably thin 1/4-inch unit hides and adjusts to almost any application. Think outside the box – and let LED Linear create a unique and impressive effect. Design Pro linear LED choices are also energy efficient and last four times longer than xenon alternatives.
