LED Modules
Instruction
J’S LED Power Inc. LED Modules are a low voltage, long life alternative to neon and florescent
lighting for channel letters, light boxes and indoor decoration. The light source for the LED
Module is the Light Emitting Diode (LED) instead of traditional neon or florescent tubes. LED
technology allows the LED Modules to provide excellent color and brightness in a safe, low
voltage circuit (12 Volts DC). LED Modules are a robust, easily installed pr
oduct designed for a
long life of safe, maintenance free operation.

Populating the Channel Letter
Populating a channel letter with LED Modules is as easy as peeling the liner off the
mounting tape and firmly pressing the light modules in the desired locations.
NOTE:
Bonding surface should be clean and dry.
To determine where the LED Modules should be placed and how many to use, J’s LED Power
Inc. offers the following guidelines: (Results may vary based upon desired light intensity and
letter construction).
1. LED Modules are designed to be place in rows:
a. LED Modules should have approximately 2.5 inch spacing between modules within the row.
This will result in 3 modules per foot.
2. LED Modules are designed to cover a stroke width of 4 inch in a channel letter (letter depth of
4 to 8 inches). Letters with a 4 inch stroke width or smaller should have one 1 row of LED
Modules. Letters with a stroke width larger than 4 inches should have multiple rows of LED
Modules placed according to the following schedule;
a. 4 to 6 inch stroke= 2 rows
b. 6 to 8 inch stroke= 3 rows
c. 8 to 10 inch stroke= 4 rows
d. Actual number of rows/modules may vary depending upon the application. The
above schedule is offered only as a guideline.
3. W hen all modules are in place, the secondary output from the power supply can be connected.
Multiple letters in a sign must be connected to the power supply in parallel. Use UL listed
Insulation Displacement Connectors to make this connection and to cap off the open ends of
the row.

If extra wire is needed
between units, use UL
listed 20 AWG or larger
Use insulating tape to connect bare wires of modules or power supplies.
Positive end and Negative end of wires should be connected accordingly.
Pull wire gently to avoid damaging modules.

4. Put Silicon Glue at least two points on each side of each LED modules.
Do not use highly acid
or alkali glue to fix modules,
such as 502 glue.

5. The modules connected in a single line of the power supply should not over 50 PCS. If
modules connect to two power supplies fore and aft ends at the same time, the quantity
can be increased to 80 PCS.
Fig.8 Lighted Channel Letter
NOTE: All LED Modules operate on 12VDC. All color modules can be connected to the same
power supply. Colors can be mixed on the same power supply. Different colors can be
connected to the same power supply and mixed on the same power supply output, while
different types cannot.
ATTENTION:
If you use our -15 and -16 modules, we strongly recommend you to have 5 inch stroke. If it is under 5
inch, the modules could be overheating, and if it is over 5 inch, it might not be bright enough as
desired.
NOTE:
Light transmittance is very important to the channel letter/light box face. Acrylic is typically used for
the letter faces and comes in a variety of colors. It is recommended to use 7328 white acrylic as your
channel letter/light box face.

Maximum Parallel Connection Quantity
Note:
Every different modules have different maximum parallel connection quantity, please check it with
table 1 below.
Attention:
We strongly recommend that do not connect 2 wires of modules in one single line together. Please
connect them in parallel. If the wires of modules are not connected to the power supply correctly,
they might not work correctly as desired.

Pow
er Supply Installation
Mounting
Mount the power supply directly to the wall with #8 or #10 pan head screws. The power supply
must be mounted in a well ventilated area that allows for accessibility after installation and must
not be adjacent to combustible materials or in an area that exceeds temperatures of 50
°
C
(122
°
F). Mount the power supply indoors, out of the weather, and do not leave exposed to rain
or water. For outdoor or wet location, power supply can be enclosed insi
de a raceway, inside
the channel letter itself, in a UL Listed for wet location transformer box or in a NEMA 3R box
with ventilation. Some acceptable Boxes for power supplies being mounted outdoors are
Hoffman p/n A12R126, Wes trim TC18SO-UL or equivalent. Use of a Class 2 power supply
can also be used for outdoor or wet locations.
Connecting the Primary
After securely mounting the power supply, have the primary connected by a licensed electrician
in accordance with local and national codes. For the 40Watt Remote Power Supply simply plug
the AC power cord into a standard 3 prong grounded outlet.
Connecting the Output
LED, Inc power supplies have Class 2 DC outputs. For reliability and performance the
following loading is not to be exceeded, usually 80 % loaded recommended.

It is recommended that the current be checked on each power supply output after loading is
complete. The current drawn by each leg should not exceed the current rating on the power supply
label. If the measured current does exceed the rated current, reduce the number of LED modules on
that leg until the current is below the rated output. The total number of module per power supply
is not to exceed the schedule as shown in Table 2.
NOTE: If any power supply output leads are left unused, the not terminated wires must be
individually capped inside an UL Listed junction box, race way or sign housing.
Routing Secondary Wires
When wiring the secondary outputs of the power supply, all routing through walls must be sealed
with outdoor rated caulk to protect the sign and building from water damage and the cable from
chafing. The power supply leads and letter to letter jumpers can be routed through walls, inside and
outside without conduit. It is recommended that all connections be enclosed in a UL listed junction
box with strain relief.
Extension of Power Supply Leads
If a longer lead wire from the power supply to lighting modules is needed, an extension
can be used. The extension should be kept as short as possible (under 15 feet for 18 AW G UL
Listed or under 50 feet for 14 AWG UL Listed).
WARNING: CHECK POLARITY
After all wire routing is complete and the lighting modules are connected to the power supply,
RECHECK THE POLARITY OF ALL CONNECTIONS. Reverse polarity connections may damage
the LED modules and voids the product warranty.

Trouble Shooting Guide
1.Entire sign or leg
with
LED Modules does not light after complete
installation.
Check the connection from the power supply lead to the first LED
Module. Makesure the polarity of the connections made at the power
supply lead and any jumperwire is correct.
2.Still does not light.
Using a volt meter check the output voltage of the power supply. The
output voltage should be 12.0VDC +or- 0.5VDC. If there is no output
voltage, have a licensed electrician check input voltage. Make sure the
power supply is hooked up correctly and getting primary power. If the
power supply is hooked up correctly and getting primary power and there
is still no output voltage, replace the power supply with a new one.
3.The beginning of a LED Module leg lights, but the entire leg does not light
or lights intermittently.
The primary cause of a portion of a LED Module leg not lighting or lighting
intermittently is a bad connection between the modules that light and the modules that
don’t light. Check this connection.
4.One LED Module does not light, but all others in the leg light.
LED Modules are designed so if one module fails, it will not cause the entire sign
or leg to go out. If one LED Module is not lighting, but all others in the leg are lighting,
replace the module with a new one.
