Annex 1
Technical Definitions
For this regulation, the following definitions shall apply:
1) 'light source' means an electrically operated product intended to emit, or, in the case of a
non-incandescent light source, intended to be possibly tuned to emit, light, or both, with
all of the following optical characteristics:
(a) chromaticity coordinates x and y in the range:
0,270 < x < 0,530; and
-2,3172 x2 +2,3653 x -0,2199 <y<-2,3172 x2 +2,3653 x - 0,1595;
(b) a luminous flux < 500 lumen per mm2 of projected light-emitting surface area.
(c) a luminous flux between 60 and 82 000 lumens; (d) a colour rendering index (CRI) >
0; using incandescence, fluorescence, high-intensity discharge, inorganic light-
emitting diodes (LED) or organic light-emitting diodes (OLED), or their combinations
as lighting technology.
High-pressure sodium (HPS) light sources that do not fulfil condition (a) are considered
light sources for this regulation. Light sources do not include:
(a) LED dies or LED chips;
(b) LED packages;
(c) Products containing a light source(s) from which these light source(s) can be removed
for verification;
(d) light-emitting parts contained in a light source from which these parts cannot be
removed for verification as a light source.
2) 'control gear' means one or more devices that may or may not be physically integrated
with a light source, intended to prepare the mains for the electric format required by one
or more specific light sources within boundary conditions set by electrical safety and
electromagnetic compatibility. It may include transforming the supply and starting
voltage, limiting operational and preheating current, preventing cold starting, correcting
the power factor and/or reducing radio interference.

a solid angle of 4 steradians under conditions (e.g. current, voltage, temperature) specified
in applicable standards. It refers to the initial flux for the undimmed light source after a
short operating period, unless it is specified that the flux in a dimmed condition or the flux
after a given period of operation is intended.

necessary for the light source to emit light at full load. But, that enable manual or
automatic, direct or remote, control of the luminous intensity, chromaticity, correlated

considered as lighting control parts.
24) 'non-lighting parts' means parts that are integrated with a light source, or physically
separated but marketed together with a light source as a single product, that are not
necessary for the light source to emit light at full-load, and that are not 'lighting control
parts'. Examples include, but is not limited to: speakers (audio), cameras, repeaters for
communication signals to extend the range (e.g. WiFi), parts supporting grid balance
(switching to own internal batteries when necessary), battery charging, visual notification
of events (mail arriving, doorbell ringing, alert), use of Light Fidelity (Li-Fi, a bidirectional,

The term also includes data-connection parts used for other functions than to control the
light emission function;
25) 'useful luminous flux' (ɸuse) means the part of the luminous flux of a light source that
is considered when determining its energy efficiency:

Cabinet Resolution of 2022 Regarding the Regulation of Outdoor Lighting Products 18
o for directional light sources with beam angle ≥ 90° it is the flux emitted in a solid angle
of π sr (corresponding to a cone with an angle of 120°);

condition of a light source, within the declared operating conditions, in which it emits
the maximum (undimmed) luminous flux;
26) 'standby mode' means the condition of a light source, where it is connected to the power
supply, but the light source is intentionally not emitting light, and the light source is
awaiting a control signal to return to a state with light emission. Lighting control parts
enabling the standby function shall be in their control mode. Non-lighting parts shall be
disconnected or switched off, or their power consumption shall be minimized following
manufacturer's instructions;
27) 'on-mode power' (Pon) expressed in watt, means the electric power consumption of a
light source in full-load with all lighting control parts and non-lighting parts disconnected.
If these parts cannot be disconnected, they shall be switched off, or their power
consumption shall be minimized following the manufacturer's instructions. In case of an
NMLS that requires a separate control gear to operate, Pon can be measured directly on
the input to the light source, or Pon is determined using a control gear with known
efficiency, whose electric power consumption is subsequently subtracted from the
measured mains power input value;
28) 'standby power' (Psb) expressed in watt, is the electric power consumption of a light
source in standby mode;

30) 'Reference control settings' (RCS) means a controlled setting or a combination of
control settings that are used to verify compliance of a light source with this regulation.
These settings are relevant for light sources that allow the end-user to control, manually
or automatically, directly or remotely, the luminous intensity, colour, correlated colour
temperature, spectrum, and/or beam angle of the emitted light. In principle, the reference
control settings shall be those predefined by the manufacturer as factory default values
-- 18 of 51 --
Cabinet Resolution of 2022 Regarding the Regulation of Outdoor Lighting Products 19
and encountered by the user at first installation (out-of-the-box values). If the installation
procedure provides for an automatic software update during the first installation, or if the
user has the option to perform such an update, the resulting change in settings (if any)
shall be taken into account.
If the out-of-the-box value is deliberately set differently to the reference control setting
(e.g. at low power for safety purposes), the manufacturer shall indicate in the technical
documentation how to recall the reference control set- tings for compliance verification
and provide a technical justification why the out-of-the-box value is set differently to the
reference control setting.
For light sources that allow the manufacturer of a containing product to make
implementation choices that influence light source characteristics (e.g. definition of the
operating current(s); thermal design), and the end-user cannot control that, the reference
control settings need not be defined. In that case, the nominal test conditions as defined
by the light source manufacturer apply;
31) 'high-pressure mercury light source' means a high-intensity discharge light source in
which the significant portion of the light is produced, directly or indirectly, by radiation
from predominantly vaporized mercury operating at a partial pressure over 100
kilopascals;

arc tube of MH light sources can be quartz (QMH) or ceramic (CMH);
33) 'compact fluorescent light source' (CFL) means a single-capped fluorescent light source
with a bent-tube construction designed to fit in small spaces. CFLs may be primarily spiral-
shaped (i.e. curly forms) or fundamentally shaped as connected multiple parallel tubes,
with or without a second bulb-like envelope. CFLs are available with (CFLi) or without
(CFLni) physically integrated control gear;
