LED lights cannot be manufactured with consistent optical properties as a result of the production processes involved. Brightness and color can vary substantially from component to component even in the same production batch. LED luminaires need to be tested during production and in their final application. Our test lab has equipments for determining luminous intensity, luminous flux, color, spectrum and spatial radiation pattern of led lights. The measurement systems generate very accurate results with reliable reproducibility in conformity with the international guidelines. Nirvana light uses high-performance spectro radiometers to deliver these solutions.
