A source of artificial light is often required when investigating photosynthesis. The light source should have a spectrum similar to sunlight, have sufficient light intensity and should illuminate the object under investigation as uniformly as possible. There is hardly a light source that adequately fulfils all of these characteristics.

High intensity white light is traditionally obtained using halogen lamps with the drawback of considerable heat production and inhomogeneous light distribution. In comparison, heat production is low in LEDs and LEDs which are regularly distributed on a panel provide homogeneous illumination. The LED light source RGBW-084 integrates both advantages and additionally allows to design the light spectra matching your experimental needs.
