High pressure sodium hps street lights.

High pressure sodium applications hps lamps unlike most metal halides do not require enclosure except to prevent moisture from accumulating on the lamp. The hps light fixture was developed by general electric and made its debut in 1964. The principal difference between low and high pressure sodium lights is the operating pressure inside the lamp. Operating hps lamps at less than full output however produces color shift changes in cri and reduced lamp efficacy.

Mercury vapor lights plant grow lights metal halide bulb e26 hid bulbs sodium vapor ballast halogen street light. Dimming is limited to about 50 of full light output. Low pressure and high pressure low pressure sodium lamps are highly efficient electrical light sources but their yellow light restricts applications to outdoor lighting such as street lamps where they are widely used. High pressure sodium hps lights are commonly used for outdoor application like parking lot lighting street lights etc.

Sodium bulbs can last up to 20 000 hours. They emit bright yellow light. There are two kinds of sodium lights. The principal difference between low and high pressure sodium lights is the operating pressure inside the lamp.

High pressure sodium vapor hps lights are a specific type of gas discharge light also known as a high intensity discharge hid or arc light. Hps fixtures quickly picked up speed and by 1970 many parking lot lights and street lights were adopting the new lighting technology. Sodium lamps were first produced commercially by philips in holland in 1932. Typically these lights are used on sides of industrial buildings and in some street lamps.

High pressure sodium lights are used for illuminating large outdoor areas. Two varieties of such lamps exist. Low pressure lps and high pressure hps these lamps are mostly used for street lighting as well as industrial uses. 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.

The heavy duty transformer or ballast is also long lived if the bulbs are changed out before they burn out. We also offer special conversion metal halide bulbs that can be used with fixtures intended for high pressure sodium light bulbs.
