LOW PRESSURE SODIUM
Buy Wholesale Low Pressure Sodium Light Bulbs
Low pressure sodium bulbs are a type of high intensity discharge lamp known for their efficiency and distinct yellow hue, which is emitted by electrically excited sodium gas contained in the bulb. This yellow hue makes them inappropriate for many purposes where color rendition is crucial, relegating them to outdoor and street lighting applications. Low pressure sodium lamps are available in a range of power ratings, from 10 Watts to 180 Watts. They are the most electrically efficient light source when judged on the amount of visible light output per Watt of power drawn. In addition, they have a very long lifespan of 18,000 hours. Unlike other high intensity discharge lamps, low pressure sodium bulbs do not diminish in light output as they age. Instead, their electrical efficiency drops as they near the end of their useful life. They have another key advantage over other high intensity discharge lamps in that they emit all of their light almost immediately after being powered on.
