High Pressure Sodium Lights Troubleshooting

I have a 150 watt high pressure sodium security light that mysteriously began cycling on and off about a month ago after about three years of faithful operation.

High pressure sodium lights troubleshooting.

High pressure sodium hps lights are commonly used for outdoor application like parking lot lighting street lights etc. Many lamp types currently offered such as metal halide and high pressure sodium lamps are physically interchangeable but not electrically interchangeable. Correcting problems with hps lamps by erik runkle and bruce bugbee high pressure sodium lamps are widely used in greenhouse production but they require maintenance for peak efficiency. This is one of the most serious maintenance problems in an hps lighting system.

They emit bright yellow light. Lamps should be checked to be sure the proper lamp type is being used according to the information on the label of the installed ballast. After visual inspection many growers find that some lamps in their greenhouse either aren t operating or aren t doing so at full brightness. Thought the photoelectric cell.

Typically these lights are used on sides of industrial buildings and in some street lamps. Sodium bulbs can last up to 20 000 hours. These lamps reduce growth and increase electric consumption. An indication of the high pressure sodium hps lamp s normal eol is on off cycling since the aging lamp requires a higher voltage for operation than the ballast can supply.

The cycling can damage or destroy the starting circuit and or ballast. Outdoor sodium lights are either low pressure or high pressure lighting to illuminate large areas with bright light. A high pressure sodium ballast is responsible for regulating the pressure in light fixtures that use high pressure sodium gas to produce the light. The heavy duty transformer or ballast is also long lived if the bulbs are changed out before they burn out.

This type of lighting is effective as a security light with a photocell to. High pressure sodium lamps are widely used in greenhouse production but they require maintenance for peak efficiency.
