at full-load;
 (c) the parts enable manual or automatic, direct or remote control of luminous intensity, chromaticity, correlated colour temperature, light spectrum or beam angle.
Example: Dimmers are lighting control parts.
lumen maintenance factor or XLMF means the ratio, for specified operating conditions, of the luminous flux of an LED lamp at a given time in its operational life to its initial luminous flux.
Note 1: In IEC standards, 'lumen maintenance' is also commonly used with the same meaning.
Note 2: In CIE standards, 'luminous flux maintenance factor' is used with the same meaning.
Note 3: The lumen maintenance factor has unit one and is usually expressed in per cent.
luminance or Lv: see subsection (2).
luminous efficacy or ηlamp: see subsection 13(2).
luminous flux or Φv:
 (a) means the change in luminous energy with time:

  where Qv is the luminous energy emitted, transferred or received, and t is time; and
 (b) for LED lamps that can be tuned to emit different light spectra or different maximum light intensities—refers to the luminous flux as measured in the reference control settings.
Note: The luminous flux is expressed in lumen (lm).
luminous intensity or Iv means the density of luminous flux with respect to a solid angle in a specified direction, calculated as follows:

  where Φv is the luminous flux emitted in a specified direction, and Ω is the solid angle containing that direction.
Note: The luminous intensity is expressed in candela (cd = lm·sr−1).
mains, mains voltage or MV means the electricity supply of 230 (+10% to -6%) volts of alternating current at 50 Hz.
mains LED lamp or MLL means an LED lamp that can be operated directly on the mains electricity supply.
Note: This includes such a lamp whether or not it can also operate indirectly on the mains using a separate control gear (including separate connected control gear) that includes a power supply converter.
mains voltage: see mains.
MLL: see mains LED lamp.
MV: see mains.
NDLL: see non-directional LED lamp.
network means an architecture (a communication infrastructure with a topology of links), and includes the physical components, organisational principles, communication procedures and formats (protocols).
networked standby mode means the condition of a CLL in which:
 (a) the lamp is connected to the power supply; and
 (b) the lamp is intentionally not emitting light; and
 (c) the lamp or separate connected control gear is awaiting a control signal via a digital network to return to a state with light emission; and
 (d) the lighting control parts are in their control mode; and
 (e) where this can be done without disassembling the lamp—when the manufacturer's instructions are followed:
 (i) the non-lighting parts are disconnected from electric power or switched
