Luckily, with the HPS bulbs, we don’t have to worry about our plants getting less light anymore. In this way, HPS bulbs can be used in indoor gardens and greenhouses in order to give plants the light that they need and make our job much easier.
What Is The HPS Bulb And How Does It Work?
High pressure sodium bulbs were invented in 1964 and they were used to help indoor plants to grow. The HPS lamp consists of a narrow arc tube supported by a frame in a bulb. Also, the arc tube has a high pressure inside for higher efficiency. Another important detail is that sodium, mercury and xenon are usually used inside the arc tube. These chemicals make the bulbs brighter when they are in use
Moreover, the arc tube is made of aluminum oxide ceramic which is resistant to the corrosive effects of alkalis like sodium. .

When it come to how they actually function, it can sound a bit complicated if you are not a specialist. However, I will try to make it sound as easy as possible. So, the bulb starts with a pulse which is created in the arc. Then, with the help of xenon gas, the bulb lights up with a light blue color. Once the arc heats up, mercury lights up the bulb with a vivid blue light. Finally, the light turns white when the sodium gas vaporizes and when the heat reaches 450 degrees Fahrenheit (250 degrees Celsius).
