They utilize a ballast and starter to provide a high voltage starting pulse.
Low pressure sodium lights vs high pressure sodium lights.
These lamps usually require between 2 500 and 5 000 volts to start the lamp.
Low and high pressure sodium lights are found in parking lots and areas where security is important.
They also produce more lumens per watt.
In this article we will take a closer look at grow lights and more specifically high pressure sodium grow lights vs led grow lights.
Led vs high pressure sodium what are high pressure sodium lights.
High pressure sodium lights have a high maintenance cost because they require monitoring and more frequent replacement of both bulbs and parts.
Because of their mercury content neither type of lamp is particularly good for the environment.
High pressure sodium lights work by creating an electric arc through vaporized sodium metal while additional materials and gases work to start the lamp and control the its color.
High pressure sodium vapor hps lights similar to lps lights are a specific type of gas discharge light also known as a high intensity discharge hid or arc light.
High pressure sodium vs led.
The principal difference between low and high pressure sodium.
High pressure sodium lamps contain mercury and sodium.
The primary visual difference between them is that metal halide light is white and the light emitted from a high pressure sodium bulb is amber orange.
The lights require up to 10 minutes to start and are best used when they can stay on for hours at a time.
High pressure sodium vs led what s the difference between high pressure sodium and led lights both metal halide and high pressure sodium bulbs are part of the hid family of bulbs.
High pressure sodium lamps last longer than metal halide.
