Compact LED Bars provide high-intensity, LED-based illumination primarily intended for plant growing under controlled light conditions. Intensity of illumination can be continuously controlled from 1 to 100 % of total output. The LED Bars can be controlled accurately by PSI’s Light Controller LC200 hardware or by PSI’s Light Studio 485 software . Both enable users to write protocols, in which light mode, intensity and timing can be set.

The sun, of course, is the primary source of daylight. When there are clouds in the sky, part of the primary sunlight is absorbed and part reflected from the clouds. The result is a combination of direct sunlight and secondary reflected light from the clouds. In a situation where the sky is completely covered with clouds, the overcast sky acts as a perfect diffusor, resulting in complete diffuse daylighting. The overcast sky lighting condition is used by architects and lighting designers to calculate the lowest level of daylight contribution in buildings. With a partly overcast or complete clear sky, the contribution will be higher. To standardize these calculations, CIE has introduced the so-called CIE overcast sky with a defined luminance distribution. The luminance of the CIE overcast sky is the highest in the zenith, the...

Compact LED Bars can be accurately controlled by the PSI Light Controller LC 200 (hardware stand-alone solution) or by the PSI Light Studio 485 software (Windows 7 or higher compatible). Both these tools enable writing of user-defined protocols, in which light mode, intensity (5-100% of total output) and timing can be set.
