Nidus (8133 profile), Linear Plaster-in Corner moulding, high density polystyrene foam, white plaster, 8ft length (heatsink & LED strip not included)
The NIDUS profile is an easy and affordable solution for light- grazing a wall, while keeping the LED source concealed and the corner visually intact. Mount over standard 2x3in. joists without the need to build elaborate wood structures, level with the gypsum panels. Paint to your liking, mount the LED profile(s) at a position yielding the desired beam direction, and let light in from apparently nowhere. Also, great above blinds or curtains!
