With up to 264 single LEDs, the bay light has two beam angles (90 and 120 degrees) which can be adjusted to shine where required, allowing optimum light distribution throughout the space. Various optics and reflectors allow the lighting to be adapted to the individual requirements of different buildings. Furthermore, the modular construction and the particularly robust design reduce time and effort spent on installation and maintenance. Integrated sensors ensure that the light is only fully illuminated when it is required. This demand-driven approach allows savings beyond those delivered by the normal reduction in consumption that results from using LED technology. Furthermore, the bay light can be used with traditional 250 or 400 watt HQL lamps.
