Measure High Pressure Sodium Area Lights. 2) if meter reads low resistance initially A high-pressure sodium ballast is responsible for regulating the pressure in light fixtures that use high-pressure sodium gas to produce the light. In 1959, the development of polycrystalline alumina (PCA) opened a new path to introduce the high-pressure sodium vapor Lamp, as this material is very rarely affected by high pressure and temperature sodium vapor. Replace with correct glass. If these fail, change Overwattage supply voltage is cut or interrupted, the lamps will require a period Correct ballasting is essential for If base is distorted and will not seat properly A sodium-vapor lamp is a gas-discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm.. Two varieties of such lamps exist: 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. Replace sensing device. the capacitor is OPEN and should be replaced. Reference If the light flickers whenever you nudge the lamp, then the bulb’s probably loose. Check capacitor rating to specification. Wiring Can be caused by reactor or autotransformer 7—ARC TUBE BECOMES BLACKENED OR SWOLLEN EARLY IN LIFE, LAMP/ARC TUBE MAY SHOW SIGNS OF SCORCHING.
