This series Grow Lights are designed as HPS Grow Light Replacement with existing electric, very convenient. This greenhouse lights are kind of plant light that can replace traditional high pressure sodium (HPS) lamp, also hid lamp, which can provide better light intensity and spectrum, thus more effectively promoting the growth and development of plants. HPS Grow Lights Replacement hydroponic lights can also be more energy-efficient, reducing the fluctuation of light intensity of plants and light loss of plants, thus saving energy.
