HPS lamps are also high pressure sodium lamps and are commonly used by indoor flower and vegetable growers today. HPS lamps are often used as a single light source throughout the vegetative and reproductive stages. To put it bluntly, using HPS lights can make plants grow faster and illuminate a wide area. HPS lights produce a lot of light and are also particularly good for blooming. But at the same time, HPS lamps also generate a lot of heat. Let me introduce you to a HPS lamp.
What is HPS?
After the high-pressure sodium lamp is charged, the arc generated between the two ends of the arc tube is utilized. Due to the high temperature of the arc, the sodium amalgam in the tube is heated and evaporated into mercury vapor and sodium vapor. As the electrons emitted from the cathode move towards the anode, they collide with the atoms of the discharge material to generate ionization or excitation, and then return from the excited state to the ground state, or from the ionized state to the excited state, and then back to the ground state in an infinite loop, At this time, the excess energy is released in the form of optical radiation, and light is produced.
So, all in all，HPS grow lights tend to be much more efficient than other alternatives and have a longer life span, saving you money on energy bills and replacements. Although they are about 30 percent more efficient than incandescent, much of the power consumed by an HPS lamp is lost as heat. Because these lamps do put out a lot of heat, it's important to keep them about 12 to 18 inches away from the plant. Anything closer than that will start to burn most plants. The heat generation may be an issue in warmer climates or the summer months, but it can help mitigate the cold in the winter or colder climates.
