INTRODUCTION to Amendment 1
EBLF is the ratio of the light output of a light source in emergency mode to the rated light
output under normal conditions. EBLF is controlled by the output characteristics (current,
voltage, power) of the controlgear with which the light source is operated.
For conventional lamps like fluorescent lamps, the EBLF is defined by the light output ratio of
the lamp operated at 100 % and in emergency mode.
EBLF = Φ / Φ
emergency 100 %
For this measurement no special lamp is required, it is expected that all lamps of the same
type show a very similar light output ratio independent of its manufacturer. The measurement
is done at an ambient temperature of 25 °C. Due to the same dimensions and the identical
cooling system (free air) the thermal conditions are identical for all lamps. The result is fully
reproducible without any additional condition.
Special requirements for LED light sources
The light output of LED light sources depends also on the temperature at which they are
operated. Typically the temperature is controlled by a heat sink on which it is mounted (e.g.
luminaire surface).
This amendment describes a test method to evaluate the EBLF via an output factor (EOF )
X
taking into account that the ratio of the forward current of the LED controlgear is directly
proportional to the LED light output. Any non-linearity due to the increased efficacy at lower
operation temperature leads to an increased tolerance of the light output in the emergency
mode but always positive.
Controlgear, which operates the LED light source in normal operation as well as in emergency
operation can be marked directly with the output factor. Controlgear, operating the LED
module in emergency mode only needs to be marked with the output value, for example the
forward current I .
emergency
1 Scope
In the last paragraph, delete the first two sentences and in the third sentence, replace the first
word "it" with "This standard".
3 Terms and definitions
3.4
Replace, in the definition, “ballast” with “controlgear”.
3.15
Delete, in the definition, the words "an automatic testing".
Add, at the end of Clause 3, the following new terminological entries:

3.16
emergency output factor
EOF

ratio of the electrical output parameter when the controlgear under test is operated in
emergency mode to the electrical output parameter when the controlgear is operated under
normal lighting conditions
EXAMPLE: I compared with I according to IEC 61347-2-13.
emergency rated
Note 1 to entry: The electrical output parameter can be current (EOF ), voltage (EOF ) or power (EOF ) at the
I U P
output(s) of the controlgear (depending on the module it could be constant current, constant voltage or constant
power).
Note 2 to entry: The emergency output factor is the minimum value measured at the appropriate time after failure
of the normal supply and continuously for the duration of the emergency operation.
Note 3 to entry: The EOF of LED controlgear used for emergency operation only, is not indicated on the
X
emergency controlgear as it depends directly also on the controlgear used for the normal operation mode. For
example for EOF it can be calculated in the final application from I and I .
I emergency normal mode
Note 4 to entry: The use of EOF higher than 1 is not suitable for direct calculation of the luminous flux of the
I
luminaire in emergency mode.

7.2 Information to be provided
Replace, in the first paragraph, “ballast” with “controlgear”.
Replace, in the second, third and tenth dashed list items, “ballast” with “controlgear”.
Replace the sixth dashed list item with the following four new dashed list items:
– declaration of the emergency ballast lumen factor (EBLF) for controlgear for fluorescent
lamp; for multi lamp controlgear the EBLF for each lamp-ballast combination;
) for LED controlgear supplying light source
– declaration of emergency output factor (EOF

in both normal and emergency operation. In case of settable electrical output parameter, a
range shall be provided or alternatively the value of the electrical parameter
(e.g. I and I from constant current controlgear) shall be provided for
normal mode emergency
the calculation of EOF.
– marking of the relevant output parameter (e.g. I from constant current controlgear
emergency
or output current range) for LED controlgear used for emergency operation only, since the
EOF is not applicable. In the case of controlgear providing different parameters from
I
constant values (e.g. a combination of constant power for some load range and constant
current for other load ranges) it shall be marked with the maximum I and details
emergency
for the parameters delivered shall be provided in the manufacturer's catalogue or similar.
– for LED controlgear providing constant current the minimum and the maximum output
voltage load shall be provided. In addition, for settable controlgear the output voltage
range shall be given for the whole range of currents in the manufacturer catalogue or
similar (e.g. table or operating area diagram).

title:

20.1 Requirements for fluorescent lamp controlgear
The requirements of 20.1 only apply to fluorescent lamps. Measurements shall be made using
a new lamp which has been aged according to the appropriate lamp standard for initial
luminous flux measurements.
The appropriate lamp associated to the controlgear shall provide the necessary light output
after changeover to the emergency mode. This is verified if the declared emergency ballast
lumen factor (EBLF) is achieved during emergency operation at 25 °C.
Compliance is checked by the following test:
