The Perifina KnifeEdge 4 in. is a surface-mounted, vanishing cove luminaire with an illuminated reveal that creates a seamless lighting effect without framing or drywall. Designed for wall-to-wall or wall-to-ceiling installation – including corners – its grooved underside allows plaster-over and painting. Available in customizable lengths, multiple lumen outputs, seven color temperatures, RGBW+ and Tunable White, the fixture delivers high color rendering and consistent light, making it ideal for both retrofit and new construction applications.
