Universal Lighting, Fulham, CREE, Halco and Eiko. The first and most obvious issue with low pressure sodium lighting is the fact that the leading manufacturer of LPS has announced that they will be discontinuing the product. QS (Qianshun) Low Pressure Sodium Lamps are ideal for roadway lighting, bridge and tunnel lighting, security lighting, area floodlighting, railway crossing lighting, airport lighting, parking and building lighting as well as LCD detection. The discharge tube may be linear (SLI lamp) or U-shaped. Bulb Angle: 360-degree bulb angle; Efficacy: High efficacy that is easily comparable to LED lights. The German physicist Leo Arons (1860–1919) studied mercury discharges in 1892 and developed a lamp based on a mercury arc. From United States. The very yellow color does not attract insects but it distorts colors. LED area lights are … Low-pressure sodium lamps have the highest efficacy of all commercially available lighting sources.

The HPS light fixture was developed by General Electric and made its debut in 1964. Low pressure sodium (LPS) streetlighting did not reappear until the mid-1970s, evidently in response to very high lamp efficiencies that had been developed (typically 100 or more lumens per watt) and the 1974 Arab oil embargo which significantly increased electricity costs in most portions of the United States. If it would not work what type of lights would? Learn how to make the switch to LEDs with Atlanta Light Bulbs. Low-Pressure Sodium Lights.
