What is a high pressure sodium fixture?
High-pressure sodium (HPS) lamps are part of the family of high intensity light bulbs that put out large amounts of light generally needed for street lighting and security lighting. The combination of metals and gasses within inside the glass tube produces an orange-white light commonly found in street lights.
Do high pressure sodium lights need ballast?
HPS lamps require ballasts to regulate the arc current flow and deliver the proper voltage to the arc. Instead, an electronic starting circuit within the ballast generates a high-voltage pulse to the operating electrodes.
Can I use a high pressure sodium bulb in a mercury vapor fixture?
Incandescent and mercury vapor lamps in exterior locations should be replaced with metal halide, high-pressure sodium and/or low-pressure sodium lamps.
How long does a high pressure sodium bulb last?
High Pressure Sodium lights maintain their luminescence fairly well with 90% still available halfway through their lifespan (around 12,000 hours). HPS bulbs typically emit 80% of their original rated output at the end of life (around 24,000 hours).
Is a high pressure sodium lamp a type of white light source?
High pressure sodium (HPS) lamps, a member of the high intensity discharge (HID) lamp family, are the most efficient white light source commercially available today.
How does the high pressure sodium lamps work?
High pressure sodium lamps are a type of gas-discharge lamp. This means they create light by sending electricity between electrodes in a bulb which is filled with a noble gas. The noble gas serves a few purposes. Due to its low thermal conductivity, it helps the lamp to start while minimizing loss of energy through heat.
What is a high pressure sodium (HPS)?
High Pressure Sodium (HPS) Definition – What does High Pressure Sodium (HPS) mean? A high pressure sodium (HPS) light is a type of growth light that is commonly used for indoor gardening. This particular light stimulates plant growth by diffusing the portion of the electromagnetic spectrum that is ideal for the whole process of photosynthesis.
What are high pressure sodium lamps?
High Pressure Sodium Lamps or HPS Lamps. High-pressure sodium lamps (also known as HPS Lamps or HPS lights) are a type of sodium lamp that is widely used in industrial lighting and many public outdoor areas.
