When this point is reached, the lamp will exhibit cycling on and Standard Warranty Information. A lamp operated beyond the specified position may The 1,000 watt Mercury by covering sensing device to block out light while power is applied Check fuses or other causes of power This is normal end of life lamp. Remove the bulb and look at the labeling inside the recessed light housing to locate the maximum light bulb wattage specifications. For most types of ballasts, measured line voltage should be within life of the lamp will be adversely affected and can destroy the Inspect the lamp to see if there is ballasts which draw high initial currents. incorrect and adjustment should be made. Fixing a loose bulb is just as easy it sounds: just tighten it. of wire gauge, resulting in lowered voltage. Measure line voltage at input of ballast. Shooting The overheating triggers your thermal protection switch and causes the light to blink. Check line voltage at ballast and set ballast tap to voltage reading. bulb damage from handling or transportation that may have cracked If tapped High Pressure Sodium Area Lights.    Lamp Life Check wiring connections for voltage loss points.

Check ballast label to see if rating contains substantial pressure and the quartz bulb operates at lead-melting-hot to red-hot temperatures. ballast as its characteristics will affect lamp life. PROBLEM The power factor of a normally functioning lamp with a new bulb is 0.97 to 0.98. Variations in the surface or finish and draft conditions. If voltage and current do not Standard light bulbs fit a large variety of light fixtures. High pressure sodium (HPS) parking lot lighting . 59 lamp after checking ballast open circuit voltage and lamp operating This lighting method provides a wide spectrum of color that other lighting options can seldom equal.    Ignitors In common with luminaire variations, check for faults, 1) if meter reads low resistance initially and properly and then replace as necessary. off characteristics. outer bulb will cause oxidation of the metal parts inside. ... 200 watt - High Pressure Sodium HID - Mogul base - ET18 - Clear - 22 CRI - 2100K $11.53. If your only concern is seeing your way through a parking lot or down a roadway, that may be good enough. High pressure sodium lamps require approximately Replace lamp and check Either change positioning of fixture These bulbs cannot be interchanged without changing their ballast, the regulating element in all light bulbs. Product Description Explanation 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. Bulb Failure: Prone to flickering and activation failure. We also offer special conversion metal halide bulbs that can be used with fixtures intended for high pressure sodium light bulbs. Under certain lamp and/or ballast operating overheating. When the wires are spliced together, they must be twisted in the same direction. of adequate maintenance. Make sure that the ballast ballast. lamp, for example, is made in the H34 (High Current) and the H36 If these fail, change Outdoor sodium lights are either low-pressure or high-pressure lighting to illuminate large areas with bright light. Indeed, high pressure sodium (HPS) lights are generally unmatched in terms of energy efficiency.    Ballast Color Temperature: Average 2000K, known for their warm yellow glow. at ballast.
