LUMINAIRE PERFORMANCE –
Part 1: General requirements
1 Scope
This part of IEC 62722 covers specific performance and environmental requirements for
luminaires, incorporating electric light sources for operation from supply voltages up to
1 000 V. Unless otherwise detailed, performance data covered under the scope of this
standard are for the luminaires in a condition representative of new manufacture, with any
specified initial aging procedures completed.
IEC 62722-1 covers requirements for luminaires to support energy efficient use and
responsible environmental management to the end of life. The object of this Part 1 is to
provide a set of requirements which are considered to be generally applicable to most types
of luminaires. Where additional performance requirements for specific types of light source
are relevant, these are specified in the IEC 62722-2 series. The IEC 62722-2 series may also
cover a wider scope of performance aspects appropriate to the particular light source
technology.
NOTE The structure of these performance standards also allows for the possibility of Part 3 standards to be
introduced in the future should standardisation of performance criteria linked to specific luminaire applications be
determined as necessary (e.g. floodlighting, street lighting, etc.).
It is the intention that the requirements of this Part 1 are to be met by the provision of
information and data provided by the luminaire manufacturer (or responsible vendor).
Conformity is considered to be met by the provision of the requested information. Any
verification of data is to be conducted by the measurement requirements of this standard.
Semi-luminaires are not covered under the scope of this standard.
For some types of luminaire (e.g. decorative/household) the provision of performance data
under the scope of this standard may not be appropriate.

Tests are made on a single sample. The luminaire shall be representative of the
manufacturer’s regular product. The luminaire should be mounted in the position in which it is
designed to operate.
B.6 Test voltage
The test voltage at the supply terminals to the luminaire shall be the rated voltage. In the case
of luminaires with a voltage range, the manufacturer shall declare the value at which the test
shall be made.
B.7 Luminaire power
The luminaire power shall be the value obtained in accordance with Clauses B.1 to B.6. The
value shall include the power of all lamp(s), controlgear and other component(s), for normal
full output operating mode or at maximum light output if the luminaire includes a dimming
controlgear. Measurements shall be made at the luminaire input terminals.
B.8 Luminaire standby power with lamps off
The luminaire standby power shall be measured with the lamps off and the luminaire
operating in standby mode only if applicable. For controlled luminaires, this is the power to
the detectors, for emergency luminaires this is the steady state power for charging the
batteries. Measurements shall be made at the luminaire input terminals.
B.9 Emergency lighting charging power
For self-contained emergency luminaires, the luminaire power for maintaining the charge in
the batteries shall be measured only with batteries in fully charged condition with lamps off. If
the input power varies with time, the power is determined as the arithmetic mean value of the
total power measured over a 24 h period following full charging of the emergency lighting
batteries. Measurements shall be made at the luminaire input terminals.

Annex D
(normative)
Photometric distribution data for luminaires
D.1 General
For the photometric distribution data of luminaires, this annex provides information and
requirements for the measurement resolution, methods of comparison, and acceptable
variation to the declared data of the manufacturer.
D.2 Measurement resolution of photometric distribution data
The consistency of photometric distribution data largely depends on the number of planes C
and angles γ used for the measurement and presented as final data. The half planes C used
to measure the intensity of the light shall cover all of the space from 0° to 360° with steps of
∆C and ∆γ as specified below.
Maximum intervals between the angles of measurement shall be as follows.
a) Luminaires for general lighting and luminaires for emergency lighting: ∆C = 15°, ∆γ = 5°
b) Floodlight and spotlight luminaires: Planes V and angles H as specified in CIE 43,
depending on the type of light beam and its angular aperture, with close stepping around
the I value. The reading can also be taken using the C-γ system, provided the steps
max
are equivalent to those prescribed by CIE 43.
c) Street lighting luminaires: Planes C and angles γ as detailed by CIE 34.
D.3 Method of comparison and acceptable limits of variation
D.3.1 The photometric distribution of the luminaire shall be measured and the light intensity
is compared to the manufacturer's declared data on the main half planes (C ; C ; C ; C );
0 90 180 270
and also on the C half plane containing the maximum intensity value, C I . For distributions
max
containing peak intensity (C I ) in more than one half plane, this comparison shall be made
max
in the same C-plane.
For luminaires exhibiting axial symmetry the comparison is made only on the main half planes
(C ; C ; C ; C ).
0 90 180 270
Before any comparison it should be ensured that the declared luminaire data and measured
luminaire data have been made for the same mounting orientation of the luminaire. If this is
not the case, the distribution may be rotated as long as this does not change any intensity
values in the process. Additionally the data shall be in the same units (cd/klm or cd)
The normalised maximum intensity value (cd/klm) of each half plane (C ; C ; C ; C ; C
0 90 180 270
I ), is compared with the corresponding 5 angles γ: I and the 4 nearest intensity
max max
readings in the same C half plane.
Table D.1 provides some examples of the nearest values to be selected for comparison.

Peak value is given in bold text.
Nearest values used for comparison are given in brackets.

For distributions where no clear peak or multiple peaks are present, it should be ensured the
comparison of intensity values are made between the same corresponding angles.
The measured data is acceptable if the corresponding values are within ±20 % of the
manufacturer's declared data.
Possible scenarios for acceptance are as follows.
D.3.2 For each main half plane – C ; C ; C ; C
0 90 180 270
D.3.2.1 Scenario 1 – Maximum intensities occur in the same γ angle
If the I and the 4 γ intensity readings nearest I fall within the specified tolerance the
max max
verdict is PASS (checked for each half plane).
If the above verdict is not PASS this check can be repeated with the half plane C shifted
within the interval C ± ∆C. If the I and the 4 γ intensity readings nearest I fall within the
max max
specified tolerance, the verdict is PASS, otherwise the verdict is FAIL (checked for each half
plane).
D.3.2.2 Scenario 2 – Maximum intensities occur in a different γ angle
If the I and the 4 γ intensity readings nearest I fall within the specified tolerance and
max max
the γ angle shift is less than or equal to ∆γ, the verdict is PASS (checked for each half plane).
If the above verdict is not PASS, this check can be repeated with the half plane C shifted
within the interval C ± ∆C. If the I and the 4 γ intensity readings nearest I fall within the
max max
specified tolerance the verdict is PASS, otherwise the verdict is FAIL (checked for each half
plane).
NOTE ∆C is the maximum measurement step for the specific luminaire type.

D.3.3 For half plane – C I
max
D.3.3.1 Scenario 1 − Maximum intensity occurs in same C plane and same γ angle
If the I and the 4 γ intensity readings nearest I fall within the specified tolerance, the
max max
verdict is PASS, otherwise the verdict is FAIL.
D.3.3.2 Scenario 2 − Maximum intensity occurs in same C plane and different γ angle
If the I and the 4 γ intensity readings nearest I fall within the specified tolerance and
max max
the γ angle shift is less than or equal to ∆γ, the verdict is PASS, otherwise the verdict is FAIL.
D.3.3.3 Scenario 3 – Maximum intensity occurs in a different C plane and same γ angle
If the I and the 4 γ intensity readings nearest I fall within the specified tolerance and
max max
the C plane shift is less than or equal to ∆C, the verdict is PASS, otherwise the verdict is FAIL.
D.3.3.4 Scenario 4 − Maximum intensity occurs in a different C plane and different γ angle
If the I and the 4 γ intensity readings nearest I fall within the specified tolerance and
max max
the C plane shift is less than or equal to ∆C and γ angle shift is less than or equal to ∆γ, the
verdict is PASS, otherwise the verdict is FAIL.
D.3.4 Conformity
Where a PASS conclusion is reached from one of the identified scenarios for D.3.2 (C ; C ;
0 90
C ; C and D.3.3 ( C I ) the measured luminaire is considered as representative of the
180 270) max
manufacturer declared data.
The ∆ angles used for the angular shifts described in D.3.2 and D.3.3 are the maximum
intervals described for the different types of luminaire given in Clause D.2. The
manufacturer's data may have been given using closer intervals.
