An under-counter lighting system places a light-guide panel (LGP) or a set of LGPs under a countertop, or another such work surface, in order to backlight it. Specifically, a base layer is secured to a support, such as a cabinet. The base layer includes a support layer and a number of support posts attached to the support layer. An LGP layer includes the LGP or LGPs. Each of the LGPs has openings that correspond to positions of the support posts, such that the LGPs receive the support posts through their thicknesses. A countertop is secured to the tops of the support posts and may have a depending lip or other such feature sufficient to hide the base layer and the LGP layer. The resulting light, usually at least partially transmitted through the countertop itself, can serve as ambient light, task light, or accent light, depending on the installation.
