PrevaLED ® Linear Value 2 | Introduction
1.4 LED module portfolio and nomenclature
The PrevaLED® Linear Value 2 is available in two different
lengths (280 mm and 560 mm) with two different lumen
packages each (650/1100 lm and 1300/2200 lm, respectively).
Every LED module type is available with three different
correlated color temperatures (3000 K, 4000 K and 6500 K),
the color rendering index for all LED module types is > 80.
The LED module nomenclature is explained below for
the example of an LED module with the following
characteristics: CCT = 3000 K, CRI > 80, nominal luminous
flux = 650 lm, length = 280 mm.
PLV: PrevaLED® Linear Value
Z: Designed for Zhaga compliance
2: Generation 2
LIN: Linear shape
650: Nominal luminous flux: = 650 lm
830: CRI > 80, CCT = 3000 K
280: Length = 280 mm (1 ft)
DC: Direct current
PLV Z 2-LIN-650-830-280-DC
The nomenclature for a module with CCT = 4000 K, CRI
> 80, nominal luminous flux = 2200 lm, length = 560 mm
would therefore be: PLVZ2-LIN-2200-840-560-DC.

Due to the special conditions of the manufacturing processes of LEDs, the typical data of technical parameters
can only reflect statistical figures and do not necessarily
correspond to the actual parameters of each single product
which could differ from the typical data.

PrevaLED ® Linear Value 2 | Introduction
1.5 Luminous fl ux as a function of forward current
The luminous flux of the LED modules depends on the
applied forward current. It is possible, however, to vary between the nominal and absolute maximum current values
for each module type and also below the nominal current,
e.g. to exactly set a requested value for the luminous flux.
The diagrams below show the luminous flux at rated conditions (tp = 55 °C) for different currents.
Please note:
LED modules with CCT = 4000 K and CCT = 6500 K
show almost similar behavior. Therefore, the curves in
the diagrams below are overlapping.

By choosing the requested luminous flux on the y-axis of
the diagram, you can derive the needed forward current
that has to be applied to the LED module on the x-axis.
Needless to say, this also works the other way around:
For a set current, you can read the corresponding luminous
flux on the y-axis.
Please note:
You can also use the OSRAM Matchmaker tool, which is
available in the OEM Download Center at www.osram.com/
oem-download, to calculate the corresponding luminous
flux and current pairs. The Matchmaker tool is presented in
chapter 4.4 and explained in more detail in the technical
application guide “OPTOTRONIC® LED drivers for indoor
application” in the chapter “The OSRAM Matchmaker –
LED modules and system compatibilities”.

PrevaLED ® Linear Value 2 | Introduction
1.6 Luminous fl ux and effi ciency as a function of tc
point temperature
All tables and diagrams shown up to now were measured
or calculated for a tc point temperature of 55 °C, the nominal temperature condition of the PrevaLED® Linear Value 2
LED modules. It is of course realistic and likely that the tc
point temperature in a given luminaire differs from the nominal conditions and that this has an impact on the luminous
flux and efficiency.
If the tc point temperature on the LED module is lower than
the nominal temperature of 55 °C, the relative luminous flux
and relative efficiency are increased.
If the tc point temperature on the LED module is higher than
the nominal temperature of 55 °C, the relative luminous flux
and relative efficiency are decreased.
The diagram below shows the correlation between the tc
point temperature and relative luminous flux/efficiency.
Since it shows only relative values, the diagram gives an
approximation that can be used for all the different module
types (e.g. different color temperatures, different module
lengths).*

PrevaLED ® Linear Value 2 | Electrical considerations
3 Electrical considerations
3.1 Wiring information
3.2 Disconnecting the wire from the connector
The connector on the PrevaLED® Linear Value 2 LED module has an easy and simple “push-in” and release mechanism. Solid wires can simply be plugged into the connector.
If fine-stranded wires are used, it is recommended to use
the release button on top of the module also for easier insertion. The wires/cables can be removed by pressing the
release button on top of the connector and pulling the
wires/cables out.
The pictures below show how to disconnect a wire from
the connector.
The connector used on the the PrevaLED® Linear Value 2
LED modules (pictured above) can handle solid wires and
fine-stranded wires with diameters from 0.5 to 1.0 mm
(AWG 24–18) and insulation diameters within 2.5 mm. The
use of solid wires is recommended.
Trim length
The trim length is recommended to be 7.5 to 8.5 mm.
Please insert wires parallel to the PCB plane.
Please note:
— The connector is designed for a maximum of 25 “pushin” and release cycles.
— The installation of LED modules needs to be carried out
in compliance with all applicable electrical and safety
standards. Only qualified personnel should be allowed
to perform installations.
— If you do not want to use solid wires, it is recommended
to use stranded wires that are tinned. Best connection
is possible with stranded wires from 0.75 mm to
1.00 mm (AWG 22 & 20) which have a maximum
diameter of ≤ 1.1 mm after tin coating.
3.3 Electrostatic discharge (ESD)
PrevaLED® Linear Value 2 LED modules fulfill the requirement of the immunity standard IEC/EN 61547. Please note
that an electrostatic discharge of more than 2 kV HBM can
cause damage, ranging from performance degradation to
complete device failure.
OSRAM recommends to handle and store all PrevaLED®
Linear Value 2 LED modules using appropriate ESD protection methods to prevent accidental damage of the modules.

3.4 Forward voltage as a function of forward current
The diagram below shows the relative dependence of the
forward voltage (Vf ) on the forward current (If ) at different
temperatures (25 °C to 85 °C) for the PrevaLED® Linear
Value 2 LED modules. It shows only the area that is of
interest for lighting applications, which is in first approximation linear. The different colors show different tp temperatures, the numbers below the diagram represent the
scaling for different LED module types (the 1100-lm and
1300-lm LED modules use the same scale).

4 LED systems: PrevaLED® Linear Value 2
and OPTOTRONIC® LED drivers
4.1 LED module/driver combinations
PrevaLED® Linear Value 2 LED modules are designed to
perfectly match OSRAM OPTOTRONIC® LED drivers – both
in the SELV (Vf <54 V) and non-isolated (V f > 54 V) range. A
single LED module is within the SELV range. By connecting
more than one module in series, the voltage reaches the
range of the OPTOTRONIC® non-isolated LED drivers.
Series and parallel connection
Multiple PrevaLED® Linear Value 2 LED modules can be
connected either in parallel or in series, as shown in the
pictures below.
PrevaLED ® Linear Value 2 LED modules connected
in parallel to an LED driver
If multiple similar LED modules are connected in parallel,
the “+” of one LED module is connected to the “+” of the
following LED module and the “-” of one LED module is
connected to the “-” of the following LED module. The last
LED module in the chain is connected to the LED driver
(here again, the “+” of the LED module is connected with
the “+” of the LED driver and the “-” of the LED module with
the “-” of the LED driver.
A schematic of four similar LED modules connected in
parallel to an LED driver is shown below, together with a
picture of two modules connected in parallel.
PrevaLED ® Linear Value 2 LED modules connected in parallel to an OPTOTRONIC ® LED driver
Example: Parallel connection of two PrevaLED ® Linear Value 2 LED modules
PrevaLED ® Linear Value 2 LED modules connected in
series to an LED driver
Multiple similar LED modules can also be connected in
series to LED drivers. A schematic of four modules connected in series is shown below.
PrevaLED ® Linear Value 2 LED modules connected in series to an OPTOTRONIC ® LED driver
The assembly can be done in two slightly different ways:
If both LED modules are in the same orientation, the wiring
between the LED modules (in series from “+” on one LED
module to “-” on the other LED module has to be done with
an “S”-shaped wire).

PrevaLED ® Core Z4 LED modules | Abschnitt
Example: Serial connection of two PrevaLED ® Linear Value 2 LED modules
LED driver
PrevaLED ® Linear Value 2 LED modules connected in
series to an LED driver – with one rotated module
If every second module in the chain connected in series is
rotated by 180°, the wiring can be done with one straight
wire (in this case, no “S” shape is needed). This can reduce
wiring effort, simplify module installation and improve the optical appearance by avoiding shadows caused by the wire.
Example: Simplified serial connection of two PrevaLED ® Linear Value 2 LED modules
LED driver
Electrically, parallel and/or series connections of similar
PrevaLED® Linear Value 2 LED modules have the following
impacts on the electrical parameters:
When connecting two modules in parallel:
Vf (two modules) = Vf (single module)
If (two modules) = 2 x If (single module)
When connecting N modules in parallel:
Vf (N modules) = Vf (single module)
If (N modules) = N x If (single module)
When connecting two modules in series:
Vf (two modules) = 2 x Vf (single module)
If (two modules) = If (single module)
When connecting N modules in series:
Vf (N modules) = N x Vf (single module)
If (N modules ) = If (single module)
Most OSRAM OPTOTRONIC® SELV LED drivers cover a
voltage range up to 54 V. That means that for using SELV
LED drivers, a parallel-only wiring of the PrevaLED® Linear
Value 2 LED modules to the LED driver is necessary. When
using LED drivers from the non-isolated portfolio (voltage
range from 54 V to 150 V…240 V), it is possible to connect
the LED modules in series to the LED driver or to use a
combination of parallel and series connection.
Defi nition of the XsYp notation:
The tables in the datasheets and on page 18 of this technical application guide use the “XsYp” notation with “X”
representing the number of LED modules that are connected
in series and “Y” representing the number of LED modules
connected in parallel.

The tables in the datasheets do not only provide information about how many LED modules can be connected
to an OPTOTRONIC® constant-current LED driver, but they
also show the recommended wiring schematics.
4.2 Installation examples
Connection scenarios of the PrevaLED® Linear Value 2 LED
modules as shown below are based on the most common
applications. Many other scenarios, e.g. three LED modules
(1s3p or 3s1p), are possible. If you have any further questions about the installation of PrevaLED® Linear Value 2 LED
modules, please consult your local OSRAM sales
representative.
Please note:
The following calculations were done using rated conditions (if not mentioned otherwise) for forward current (If ),
luminous flux etc. These settings can, of course, be adjusted. This can change the LED module/LED driver combinations listed in the examples.
Example 1: 1s5p – Five LED modules connected
in parallel to an OPTOTRONIC ® SELV LED driver
Application example: 5 ft (≈ 1500 mm) damp-proof luminaire
Example components: PrevaLED® Linear Value 2:
PLVZ2-LIN-1100-840-280, five modules
Five LED modules connected in parallel to an OPTOTRONIC ® SELV LED driver
Electrical parameters of one PLVZ2-LIN-1100-840-280:
Forward current (If ) = 200 mA, forward voltage (Vf ) = 35 V
Five LED modules connected in parallel:
Forward voltage: Vf (five modules) = Vf (one module) = 35 V
Forward current: If (five modules) = 5 x If (one module) =
1000 mA
From the OSRAM LED driver portfolio,
there are some drivers that would fit, e.g.:
— OT FIT 50/220-240/1A0 CS L
(as a linear on/off driver)
— OTi DALI 50/220-240/1A4 LT2 L
(as a linear dimmable DALI driver)

PrevaLED ® Linear Value 2 | LED systems: PrevaLED ® Linear Value 2 and OPTOTRONIC ® LED drivers
Please note:
If the LED modules are connected in parallel to the LED
driver, it is possible to combine 280 mm LED modules and
560 mm LED modules with the same LED pitch (i.e. 650 lm
LED modules with 1300 lm LED modules and 1100 lm LED
modules with 2200 lm LED modules). The main benefit is
that less components have to be connected and assembled. The electrical parameters remain unchanged.
For our example, this means:
Electrical parameters of one PLVZ2-LIN-1100-840-280:
If = 200 mA, Vf = 35 V, of one PLVZ2-LIN-2200-840-560:
If = 400 mA, Vf = 35 V
Parallel connection of 2 x PLVZ2-LIN-2200-840-560 +
1 x PLVZ2-LIN-1100-840-280:
Vf (2 x PLVZ2-LIN-2200-840-560 + 1 x PLVZ2LIN-1100-840-280) = Vf (one module) = 35 V
(same as before)
If (2 x PLVZ2-LIN-2200-840-560 + 1 x PLVZ2LIN-1100-840-280) = 2 x If (PLVZ2-LIN-2200-840-560) +
1 x If (PLVZ2-LIN-1100-840-280) = 2 x 400 mA + 1 x
200 mA = 1000 mA
(same as before)
Example 2: 4s1p – Four LED modules connected in
series to an OPTOTRONIC ® non-isolated LED driver
Application example: 4 ft (≈ 1200 mm) damp-proof luminaire
Example components: PrevaLED® Linear Value 2:
PLVZ2-LIN-1100-840-280, four modules
Four LED modules connected in series to an OPTOTRONIC ® non-isolated LED driver
Electrical parameters of one PLVZ2-LIN-1100-840-280:
If = 200 mA, Vf = 35 V
Four LED modules connected in series:
Vf (four modules) = 4 x Vf (one module) = 140 V
If (four modules) = If (one module) = 200 mA

recommended drivers are, e.g.:
— OTi 60/220-240/550 D LT2 L
(as a linear on/off driver)
— OTi DALI 60/220-240/550 D LT2 L
(as a linear dimmable DALI driver)

4.4 The OSRAM Matchmaker tool
In order to support customers in finding the right combination of LED driver and LED modules and in addition to the
system combination tables shown in the previous section,
OSRAM offers an Excel-based calculation tool called the
OSRAM Matchmaker, which is available in the OEM Download Center at www.osram.com/oem-download. On the
next few pages, a short overview of the most relevant parts,
adapted to the PrevaLED® Linear Value 2 LED modules, is
provided. A more complete overview can be found via the
hyperlink at the end of the chapter.
If you download the OSRAM Matchmaker tool and open
the Excel file (make sure macros are allowed in your Excel
application), the following menu is shown:
OSRAM Matchmaker tool – main window
The tool consists of three parts:
— Input data
— Output data
— Diagrams
In the section “INPUT DATA”, the user can select a combination of LED driver and LED modules and set all relevant
module driving parameters: temperature, current and luminous flux. The user can also find the configuration of the
selected system (system setup), i.e. the wiring of the selected LED module/driver combination, at the bottom of this
section. By pressing the “Select Module & Driver” button,
the following window with a selection of different LED
modules and LED drivers pops up.

to 5 are the different selection steps:
Selection of “PrevaLED® Linear Value 2” from the
OSRAM LED module portfolio listed in the selection
window.
2 Selection of the LED module type for your application
(650/1100/1300/2200 lm version).
3 Selection of the color temperature and color rendering
index for you application.
4 Selection of the number of LED modules that you want
to use in your luminaire with one LED driver.
Attention:
For some numbers, more than one selection is possible
(in the picture above, for example, the selection of 2 to 10
LED modules is possible). The different selections show
different possibilities of connecting the LED modules to the
LED driver (see page 14 for more details).

Four LED modules can, for example, be connected
as follows:
— 1s4p, meaning all four LED modules are connected
in parallel to the LED driver
— 4s1p, meaning all four LED modules are connected
in series to the LED driver
— 2s2p, meaning two LED modules in series are
connected in parallel to the LED driver

5 Shows possible LED drivers from the OPTOTRONIC ®
portfolio for the LED module configuration selected in steps
1 to 4. In most cases, more than one LED driver is listed.
The listed LED drivers mainly differ in terms of performance
(e.g. on/off or dimmable, single current/multi current selection, current range etc.).
In the example above, the following LED drivers are
listed:
OT FIT 50:
On/off driver with one fixed current (250 mA)
OTi 60:
Intelligent LED driver with selectable current
from 120 mA to 550 mA (by LEDset)
OTi DALI 60: Intelligent LED driver with selectable current
from 120 mA to 550 mA (by LEDset or DALI
programming), DALI programmable and
dimmable
By selecting one of the possible LED drivers and clicking
the “Select System” button, the selection is completed and
the selection window is closed. Completing the selection
takes you back to the main window which could, for example, look like the one on the next page (the features highlighted in blue were selected in the selection window
above).
Needless to say, the selection of how the LED modules are
connected to the LED driver has an impact on which LED
drivers from the OPTOTRONIC® portfolio can be used.
In the example with four LED modules:
— 1s4p (and in general all combinations with 1s) is used
together with a SELV LED driver
— 4s1p and 2s2p (and in general all combinations with >1s)
are used together with non-isolated LED drivers

driver OTi DALI 60
The column “INPUT DATA” initially shows the nominal
values for the selected PrevaLED® Linear Value 2 LED
modules and the selected configuration (X modules in
parallel, Y modules in series).
OSRAM Matchmaker tool – “OUTPUT DATA” part of the main window
The column “OUTPUT DATA” shows the different values
(e.g. luminous flux and efficacy) for the minimum, nominal
and maximum allowed forward currents for the chosen
system. Highlighted in orange in the example above, the
minimum system forward current is 120 mA, limited
by the minimum output current of the chosen LED driver,
the nominal system forward current is 200 mA and the
maximum system forward current is 300 mA, limited by
the maximum allowed forward current for the selected LED
module (PLVZ2-LIN-1100-840-280-DC).
This also shows that the forward current in the example
can be selected in the window from 120 mA to 300 mA
in order to adjust the luminous flux more precisely to the
value needed in the application and/or luminaire. So, if
5000 lm are needed in the application, this is possible with
the chosen LED driver/modules combination because
5000 lm lies in the flux window listed in the picture above
(from “Sys min” = 2496 lm to “Sys max” = 6240 lm).
The OSRAM Matchmaker tool also helps finding the exact
value to achieve the 5000 lm needed. This can be done by
entering a target luminous flux in the “INPUT DATA” window
(in the highlighted position called “target flux”).

OSRAM Matchmaker tool – target flux setting and resulting parameters
In the “OUTPUT DATA” window above, the corresponding
column with the values for the selected target flux is highlighted. Here, for example, the current has to be set to
240 mA for a tc point temperature of 55 °C. It is also possible to set a target forward current (“target current” in the
“INPUT DATA” window) and see the corresponding values
(e.g. the luminous flux) in the target current columns of the
“OUTPUT DATA”.
More detailed information about the Matchmaker tool (e.g.
temperature-dependent data, diagrams, LEDset resistor
corresponding to the forward currents etc.) can be found
in the technical application guide “OPTOTRONIC® LED
drivers for indoor application” in the chapter “The OSRAM

PrevaLED ® Linear Value 2 | Thermal considerations
5 Thermal considerations
PrevaLED® Linear Value 2 LED modules are described as
“self-cooling”. That means that at rated operating conditions, no additional heat sink is needed to avoid exceeding
tc max = 70 °C when the LED modules are mounted
onto or into a luminaire housing with heat exchange to
the environment.
To verify correct self-cooling, it is nevertheless strongly
recommended to check the LED module temperature in
any newly designed luminaires.
It should also be mentioned here that lower tc point temperatures on the LED module increase the module’s efficiency.
Therefore, providing efficient cooling for the PrevaLED® Linear
Value 2 LED modules increases the system efficiency of the
luminaire/application.
5.1 Introduction and defi nitions
For any LED module, including the PrevaLED® Linear Value
2 family, different temperatures (tp, tc, tc max etc.) are
mentioned in the datasheet. They are sometimes confused,
therefore a short overview should be given at the beginning
of this chapter:
— The tp values are the performance temperatures of the
LED module. In principle, many different performance
temperatures can be defined for an LED module, e.g.
tp,rated, tp,1, tp,2, …. The different temperatures can be connected to different parts of the LED module specification (e.g. different tp temperatures leading to different
LED module efficacies). For the PrevaLED® Linear Value 2,
there is only one (rated) performance temperature defined in the datasheet: tp, rated = 55 °C. For simplification,
it is often only called tp temperature/performance temperature of the LED module.
— The tc temperature, the rated maximum temperature,
is the highest permissible temperature which may occur
at the LED module temperature measurement point
under normal operating conditions and within the rated
current/voltage/power range of the LED module.
All the temperatures mentioned above are measured at
the same point on the LED module, which is (mostly for
historical reasons) called the “tc point” of the LED module.
Its position on the PrevaLED® Linear Value 2 LED modules
is shown in the next section.
5.2 tc location and measurement
Proper thermal design of an LED luminaire is critical for
achieving best performance and ensuring long lifetime of
all components. To achieve a lifetime of 50000 hours
(L80B10), the sufficient heat exchange and thermal conduction between the light engine and the luminaire housing
has to be verified by measuring the temperature at the tc
point.
The maximum temperature reached at the tc point must
not exceed 70 °C. This reference point for PrevaLED ®
Linear Value 2 is shown in the image below for the
1100-lm/280-mm LED module type (for the other LED
module types, the position is similar).
Position of the tc measurement point on PrevaLED ® Linear Value 2 LED modules
tc measurement point
The easiest way to measure the temperature at the tc point
is by using a thermocouple. It is recommended to use a
thermocouple that can be glued onto the LED module.
Make sure that the thermocouple is fixed with direct contact to the tc point.

5.3 Forward voltage as a function of tc point temperature
The diagram on the right shows the relative dependence of
the forward voltage on the temperature at the tc point of the
LED module (down to a temperature of 20 °C). The voltage
increases with decreasing temperature. Therefore, when
looking for a suitable LED driver, the forward voltage of
the system at the coldest specified temperature has to be
considered. For OSRAM system combinations of LED
modules and LED drivers, temperatures down to -20 °C
are tested and released and full functionality is guaranteed.

PrevaLED ® Linear Value 2 | Lifetime and lumen maintenance
6 Lifetime and lumen maintenance
For the definition of the lifetime of an LED module, see
IEC 62717, where the following types are defined:
Average lifetime vs. tc point temperature
tc life [h]
The luminous flux of an LED module decreases over its lifetime. This decrease is specified by the L value. L70 for example means that at least 70 % of the initial light output is
emitted by the LED module. The L value is always connected to an operating time and defines the lifetime of an LED
module. Please be aware that the L value is a statistical value, therefore the extent of the decrease in light output can
and will vary for different modules.
L70B50
70000
60000
50000
40000
30000
20000
The B value specifies the maximum percentage of LED
modules below a stated limit, e.g. B50 means that a maximum of 50 % of the LED modules are below a given L value.
The C value gives the number of abrupt failures, meaning
the number of LED modules that are not operating any
more and do not emit any light at all (e.g. C10 after 50000
hours means that after 50000 hours in operation, a maximum of 10 % of the LED modules do not emit any light).

The F value is the combination of the B and C value, meaning that both abrupt failures and parametric failures due to
lumen degradation are considered.

Some examples:
— L0C10 is the lifetime where the light output is 0 % for a
maximum of 10 % of the LED modules.
— L70B50 is the lifetime where the light output is ≥ 70 %
for a maximum of 50 % of the LED modules. The B value
includes only gradual reduction of lumen output over
time (not the abrupt lumen output loss).
— L70F50 is the lifetime where the light output is ≥ 70 %
for a maximum of 50 % of the LED modules. The F value
includes reduction of lumen output over time including
abrupt lumen output loss (flux = 0).

Operating lifetime [h]
PrevaLED® Linear Value 2 LED modules have a lifetime of
50000 hours (L80B10) at a tc point temperature of 55 °C.
This means that after 50000 hours, a minimum of 90 %
of the utilized LED modules will maintain at least 80 % of
the initial luminous flux.
Please note:
A higher tc point temperature leads to a shorter lifetime
of the LED module. Moreover, the failure rate will also
increase.

7 Mechanical considerations
7.1 LED module dimensions
The PrevaLED® Linear Value 2 family has two types of LED
module length: 280 mm and 560 mm. For the 280 mm LED
modules, versions with a nominal luminous flux of 650 lm
and 1100 lm are available, and the 560 mm versions are
available with 1300 lm and 2200 lm.

7.3 Mechanical protection
For operation in damp, wet or dusty environments, the user
has to make sure that an adequate ingress protection (IP)
is chosen. The LED module has to be protected by a suitable IP rating of the luminaire housing. Please consider
the luminaire standard IEC 60598 amongst other requirements.
7.4 Mounting instructions
Please apply force only to the dedicated mounting positions. Strong mechanical stress can lead to irreversible
damage of the LED module. To fix the module to the
fixture, you can use M4 screws according to DIN 7984
or DIN EN ISO.
The maximum allowed screw head diameter without using
an isolating washer between the screw and the mounting
hole is 7.5 mm. With larger screw heads, the minimum
distance between the screw head and other conductive
parts on the PrevaLED® Linear Value 2 LED module can be
below the limit for creepage distances.
The maximum torque that should be applied on the screws
depends on factors such as the the screw type and the
luminaire material. It is also influenced by the usage of
washers. In most cases, a torque between 0.5 Nm and
1 Nm is enough to fix the LED module in the luminaire
housing and will not damage the module.

It is also possible to use clips instead of screws,
e.g. the push-to-fix (P2F) connectors from BJB:
www.bjb.com.
To achieve optimal fixation of the LED module and also
optimal thermal management, it is recommended to use
all mounting holes in the PrevaLED® Linear Value 2 LED
modules. Nevertheless, it is possible to reduce the number
of screws to three per 280-mm module and six per
560-mm module, respectively.
In any case, it is strongly recommended to perform
mechanical and thermal testing of the LED modules in
a given luminaire.
