Which is better, quantum board or high-pressure sodium (HPS)?

Quantum Board LED and high pressure sodium (HPS grow lights)

The difference between quantum board and HPS light is a common problem for new growers. In the past few decades, fluorescent grow lamps, high pressure sodium lamps (HPS) and metal halide grow lamps have been used as the source of plant growth and have always been the standard grow lights. With the development of science and technology, LED grow lighting will be a better choice in almost all marijuana plants cultivation applications in 2020. LED grow lights and led upgraded quantum board plant lamps are gradually emerging, occupying a larger market share of plant grow lamps. LED grow light is replacing traditional grow light sources with its characteristics of high efficiency and energy saving.

High pressure sodium grow lights (HPS) are less efficient than LED grow lights. Up to 70% of the energy is wasted as heat, and then you need to consume more energy to remove the heat from the growing area. No matter what kind of light source is used, Watt and heat are directly equivalent.

The biggest difference between quantum board led grow lights and high-pressure sodium lamp is that although the initial cost of HPS grow lamp is cheaper, it will consume more electric energy. However, this electric energy will convert more heat energy that plants do not need. So you have to increase the cost by adding fans or cooling equipment.
