Google has not performed a legal analysis and makes no representation or warranty as to the accuracy of the list.) Needs capacitor in its autotransformer circuit to improve the power factor which is very low C. Comes up to its rated output in approximately 15 minutes D. All of the above This makes HPS lamps especially easy to use in many fixture types. This is because most of the light emitted from a sodium vapour lamp is concentrated in the yellow part of the visible spectrum (around 580-590 nm). O    Moreover, the virtual insensitivity of HPS lamps to burning position means that fewer lamp types are needed as compared to metal halide. A low-pressure sodium-vapour (LPS) lamp contains an inner discharge tube made of borosilicate glass that is fitted with metal electrodes and filled with neon and argon gas and a little metallic sodium.
