High Intensity Discharge lamps are often compared to your everyday incandescent light bulb. But these HID lamps are very different, not only in size but how they produce light.

In this video we will focus on the center of a High Pressure Sodium lamp. Looking at the actual light source we will see how it produces its high intensity light.

The Arc Tube is the light producing source. It is called an Arc Tube because electricity jumps or arcs from one side of the tube to the other. Notice there is no filament producing a glowing light. An arc is very similar to a lightning strike, only much lower in terms of power and much longer in time duration.

Electrodes are on each end of the arc tube. The electrodes provide a starting point and ending point. The lamp current flows between the electrodes.

By adding low pressure fill gas and materials like mercury and sodium allows the arc to become much brighter.

When using a 1000 watt HPS lamp the power is turned on. an external ballast provides a 4,000 volt starting pulse which begins to break down the fill gas starting a flow of electrons. The arc produces a faint glow of light and heat.

Heat from the arc vaporizes the liquid mercury into a gas and the mercury enters the arc stream. The arc constricts and gets brighter generating more heat.

Heat from the mercury arc vaporizes the sodium into a gas allowing it to enter into the arc stream as well. Once this has happened the arc stream has reached its optimal operating temperature producing a quality light spectrum for indoor plant growth.

HID lamps contain similar components. What makes EYE HORTILUX lamps unique is our exclusive chemistry. This chemistry produces the light spectrum specifically designed for plant growth. This results in a high quality high yield product.
