Low Pressure Sodium
Performing at 140lumens/watt and better, the low pressure sodium bulb is one of the most efficient light sources available to consumers. These lamps are used primarily in street lighting, commercial lighting, and industrial lighting applications. Philips’ SOX low pressure sodium lamps are the most efficient and high performing lamps available and have saved cities, states, local governments, and other institutions money due to their low operating costs. The low pressure sodium bulb has some unique properties that make it optimal for street and highway lighting. The first is that the color temperature it produces (1,800K) occurs at point on the color spectrum to which the human eye is most sensitive, thus maximizing the visibility of the roadway and making it safer for drivers and pedestrians. Secondly, "low pressure sodium" lamps produce little glare which reduces drivers’ eyestrain and makes operating your vehicle that much safer.
