Nightlux Stair LED stair light for more safety in the dark The Nightlux Stair LED stair light is ideal for illuminating dark corners in stair areas. The light is designed in such a way that it emits light downwards only and, above all, evenly diffused through a white polycarbonate diffuser. The integrated sensor ensures that it does not light up permanently, but only when it detects movement. Battery operation and quick and easy installation thanks to the fixing material supplied make the Nightlux Stair a flexible light source. The new LEDVANCE products, formerly known under the OSRAM brand name, combine the highest quality standards with modern design.
