The semi-autonomous circular luminaire from LEDCity even recognises when and where light is needed. It is not dependent on a central control system, as each luminaire independently provides the best possible local lighting conditions by means of sensors. This significantly reduces energy consumption, installation and maintenance costs. A further advantage: the round luminaire has a modular design, so that in future the light source can be replaced in a few simple steps without having to replace the entire luminaire. In addition, parameters can be set on the product to save the optimum amount of energy for each application.
