Black Foster is the product that transfers the claimed effect " The Invisible Black" to a recessed-isolated lineal luminary; also available in trimless version.‎ If we take a closer view to the recessed model, its bezel is so thin than when lighted up, it is unperceived; offering an aesthetic of "visual trimless".‎ Black Foster stands out for its refinement, its visual comfort and for almost completely hide the source of light from the human eye range.‎
