NS51 is closely related to the NS50 and is therefore also an exclusive and customisable linear LED fixture, specifically developed as a continuous light row system. This fixture is customisable in length to fit your exact project and can be installed as a pendant fixture, as a wall-mounted fixture, as a ceiling mounted fixture and as a trim-less built-in fixture. NS51 differentiates from the related NS50 through the use of optics that narrow the light and enable directional lighting. The use of optics also means that NS51 can be delivered with a vertical optic which directs the light to the sides instead of a normal diffusion. The vertical optic is highly suitable for supermarkets, as the light can be directed onto shelf displays. NS51 is delivered with a Samsung board of high quality and an internal Tridonic driver that simplifies the installation process.
