Lumatek too makes use of the blue light colour spectrum for its metal halide growth-spectrum grow lights. With a colour temperature of 4328K, the 400W version can give off an astonishing 44,000 lumens. The PAR value (photosynthetically active radiation) indicates the spectral range of sunlight used by living organisms to perform photosynthesis. Tables and diagrams provide better explanations for this.

Light is a crucial requirement for photosynthesis, and therefore also for the growth of any plant. Plants thrive best in sunlight, as this provides a balanced light spectrum. However, plants can?t always be grown outside. In most cases, conventional indoor lighting is not sufficient to ensure good photosynthesis performance.
