The EVO 5-100 is specifically designed for high open areas and is clearly conceptualized for professional plant cultivation and not for the home user. Due to the power of 870µmol/s at 320W, the luminaire produces a lot of light to achieve very high lighting intensities even with distance between luminaire and plants. Even though a single luminaire with 870µmol/s theoretically provides enough light to illuminate one square meter, we recommend in principle two luminaires per square meter for the most uniform illumination.
