5  Definitions—other expressions used in this instrument

            Note 1: A number of expressions used in this instrument are defined in section 5 of the Act, including the following:
● category A product;
● covered by;
● family of models;
● GEMS;
● GEMS labelling requirements;
● GEMS level requirements;
● model;
● product classes.
Note 2: Many of the following definitions are based on ILV (the International Lighting Vocabulary) or IEV-845 (the part of the International Electrotechnical Vocabulary that deals with lighting).  Where the definition of an expression below differs from the ILV or IEV definition, the definition in this instrument takes precedence.
 (1) In this instrument:
Act means the Greenhouse and Energy Minimum Standards Act 2012.
average luminance, in relation to an LED lamp, means the average luminance over a light-emitting area where the luminance is more than 50% of the peak luminance (cd/mm2).
beam angle of a directional LED lamp:
 (a) means the angle between 2 imaginary lines in a plane through the optical beam axis, such that these lines pass through the centre of the front face of the LED lamp and through points at which the luminous intensity is 50% of the centre beam intensity; and
 (b) for LED lamps that have different beam angles in different planes—refers to the largest beam angle; and
 (c) for LED lamps with a user-controllable beam angle—refers to the beam angle as measured in the reference control settings.
Note: The beam angle is a full angle measure, not a half angle measure, and is expressed in degrees (°).
cap means that part of a lamp which provides a connection to the power supply by means of a lamp-holder or lamp connector and, in most cases, also serves to retain the lamp in the lamp-holder.
Note 1: The standard code for identifying cap types can be found in IEC 60061.1: Lamp caps and holders together with gauges for the control of interchangeability and safety – Part 1: Lamp caps.
Note 2: The term 'base' is equivalent to 'cap'. The term 'cap' is used in this instrument.
CCT: see correlated colour temperature.
centre beam intensity means the value of luminous intensity measured on the optical beam axis.
chromaticity means the property of a colour stimulus defined by:
 (a) its chromaticity coordinates (u′ and v′), or (x and y); or
 (b) its dominant or complementary wavelength and purity taken together.
CLL: see connected LED lamp.
colour consistency means the maximum deviation of the initial, spatially averaged chromaticity coordinates (x and y), or (u′ and v′), of an LED lamp from the rated chromaticity centre point (cx and cy) or (cu′ and cv′), expressed as the step size of:
 (a) the MacAdam ellipse formed
