** A modified spectrum lamp means a lamp, other than a coloured lamp, that

  • is marketed as a modified spectrum lamp, and
  • when operated at its nominal voltage and nominal power, has a colour point that, on the 1931 chromaticity diagram described in CIE 15 (2004), lies below the black-body locus and that is at least 4 MacAdam steps, as described in IES LM16 (1993), distant from the colour point of a clear lamp with the same filament and bulb shape and operating at the same nominal voltage and nominal power.

a modified spectrum incandescent lamp

A modified spectrum incandescent lamp means a modified spectrum lamp** that has

  • a luminous flux of at least 232 lm but no greater than 1 950 lm,
  • a nominal voltage of at least 110 V but not more than 130 V or a nominal voltage range that lies at least partially between those voltages, and
  • a screw base,

but it does not include

  • an appliance lamp*,
  • CFL*,
  • an explosion resistant lamp, namely, a lamp that is designed and certified to operate in a Class I, Division 1 or Class II, Division 1 environment as defined in the IEC standard CEI/IEC 60079-0 (2007) entitled Explosive atmospheres – Part 0: Equipment – General Requirements,
  • an infrared lamp*,
  • a lamp that has a G-shape as specified in ANSI C78.20 and ANSI C79.1, with a diameter of 12.7 cm or more,
  • a lamp that has a T-shape as specified in ANSI C78.20 and ANSI C79.1 and a maximum nominal power of 40 W or a length exceeding 25.4 cm,
  • a lamp that uses solid state technology, namely, a lamp with a light source that comes from light-emitting diodes,
  • a left-hand thread lamp, namely, a lamp with a base that screws into a lamp socket in a counter-clockwise direction,
  • a plant lamp*,
  • an incandescent reflector lamp* that has a shape specified in ANSI C79.1,
  • a sign service lamp, namely, a vacuum type or gas-filled lamp that has sufficiently low bulb temperature to permit exposed outdoor use on high-speed flashing circuits and is marketed as a sign service lamp,
  • a silver bowl lamp*,
  • a traffic signal module*, a pedestrian module* or a street light,
  • a submersible lamp*,
  • a lamp that has a screw base size of E5, E10, E11, E12, E17, E26/50×39, E26/53×39, E29/28, E29/53×39, E39, E39d, EP39 or EX39 as specified in ANSI C81.61,
