Things You Should Know About HPS Grow Bulbs

High-Pressure Sodium or HPS was first invented in 1964 as a light technology. Ever since its invention, HPS bulbs were popular, applied in the industrial lighting industry, and were also used as grow lights for plants. Manufacturing facilities were also known for using these types of bulbs.

Inside the tubes of HPS bulbs are the elements, xenon, sodium, and mercury. These elements are often used to improve and enhance the light spectrum. An HPS bulb is kept at very high levels of pressure to increase its efficiency.

How to Use 600w Grow Bulbs And ballast?

The most common way of turning on an HPS bulb is to begin it with a pulse. The elements that are found in the tubes of HPS bulbs— xenon, sodium, and mercury— work together to light up the bulb.

  • The process starts with xenon gas starting the arc by using that pulse, once the arc is on, the lamp will turn into a light shade of color blue. The mercury, which was gradually heated by the arc, will then light up and emit a bluish color to the bulb.
  • Once the bulb gets hot and the sodium begins to vaporize, an arc will be forced to reach over 240 degrees Celsius (450 degrees Fahrenheit), which will result in a combination of sodium and other chemicals to produce a ‘white’ light.
  • Similarly, the Mercury will add its blue light to the natural yellow spectrum.
High-Pressure Sodium technology is widely chosen due to the power of the light that will offer spectrum which could help your garden plants grow very well
