HPS vs LED Cost and Efficiency: Initially, LED lighting options for parking lot lights and street lights are going to cost more than HPS lighting. Abstract. There are several advantages and disadvantages of high pressure sodium lamps. Better efficiency, life and size are few of the advantages of HPS Lamp over LPS Lamp. Advantages: Most energy efficient among all artificial light sources. High pressure sodium lamp will flash with white and gold when using. Non-passive arc tube failures caused by end of life conditions of the lamp, by ballast failures or by the use of an improper lamp-ballast combination may cause the breakage of the outer bulb of the metal halide lamp. Consuming high levels of sodium can have many negative health effects, such as increased blood pressure and heart complications. If such a lamp breaks, the exposed sodium metal can result in a fire. Energy efficient – LED’s are now capable of outputting 135 lumens/watt Long Lifetime – 50,000 hours or more if properly engineered. Color temperature is always warm Roadway lighting). HPS Lamp is the better version of its counterpart LPS Lamp. Back in the day, more wattage meant more brightness. More. White-Lux SON lamps are a metal halide lamp designed to work in a standard SON fitting. A final advantage is that in the case of a momentary power supply interruption, the lamp will restrike as soon as the power is restored and no cooling down period is required. advantages and disadvantages of high pressure sodium lamps.
