NEMA wattage label

NEMA wattage labels are standardized labels defined by the National Electrical Manufacturers Association (NEMA) used on street lighting fixtures to indicate the wattage of the lamp for maintenance purposes. Additionally, various colors are used to identify what type of lamp the fixture uses.

A yellow sticker indicates the lamp is a sodium vapor lamp (HPS/LPS). A blue sticker indicates the lamp is mercury vapor (MV). A red sticker indicates the lamp is metal halide (MH). A sticker that is half-red and half-white indicates a pulse start metal halide lamp (PSMH). Green is also used on HPS units in Canada. White indicates that the fixture is of an LED type.

In addition to being colour-coded, newer NEMA stickers also state the lamp type abbreviation just below the lamp's wattage (e.g. HPS, LED).
