The monochromatic output of the low pressure sodium lamp precludes its use from all indoor general lighting applications, and all outdoor applications where colour rendering is required. Sodium Lamps were first produced commercially by Philips in Holland in 1932. Moreover, the virtual insensitivity of HPS lamps to burning position means that fewer lamp types are needed as compared to metal halide. Put them in a sealed plastic bag and take it to your local waste facilities for recycling. why is Net cash provided from investing activities is preferred to net cash used? They are widely used on the streets for lighting purposes. This makes HPS lamps especially easy to use in many fixture types. A Low-Pressure Sodium Vapor lamp (or LPSV lamp) is termed as a “miscellaneous discharge lamp” as it possesses some characteristics of High-Intensity Discharge (HID) lamps as well as it resembles fluorescent lamps in other areas.
