HF
2
Chain
High Flux LED Module Ideal for Signage Applications
Key Features & Benefits
• Available in a standard version
(25 LPW, 110 lumens/ft.) or as a
high efficiency version (70 LPW,
154 lumens/ft.)
• Narrow profile and wide beam angle
(120º) allow for uniform illumination
of backlit surfaces
• Flexible cables enable luminance to
be adjusted
• Each HF
2
Chain can be cut every
three boards to fit any application
• Dimmable by pulse width modula-
tion, a method that maintains
consistent lumen output and color
• Circuit boards are conformally
coated to protect against dust,
moisture and condensation
• Single board add-ons are available
to adjust length and fine tune light
output
The SYLVANIA HF
2
Chain LED module offers a cost effective alternative to
traditional white neon sources. The primary advantage of the LED module
over neon sources is reduced manufacturing and maintenance costs,
durability and small size. The HF
2
Chain LED module is ideally suited to fit
contours and curves typical of advertising spaces and channel letters.
Each HF
2
Chain consists of eighteen metal circuit boards, each with two
high-flux LEDs. Available in a standard version (25 LPW, 110 lumens/ft.) or
a high efficiency version (70 LPW, 154 lumens/ft.), this versatile product
enables the design of smaller and sleeker signs.

*OT240 is a power supply with three 80W Class 2 power output.
Notes:
1. The HF
2
Chain SB is a single board designed to give greater control and flexibility over chain length. An HF
2
Chain module at any given length, can be lengthened by adding
one of two HF
2
Chain single boards, if desired.
2. SYLVANIA OPTOTRONIC power supplies are specifically designed with protection features for safe operation.
Safety Information
WARNING: ONLY QUALIFIED PERSONNEL SHOULD PERFORM INSTALLATION.
TO AVOID ELECTRICAL SHOCK OR COMPONENT DAMAGE, DISCONNECT POWER BEFORE
ATTEMPTING INSTALLATION OF THE POWER SUPPLIES AND/OR MODULES.
Failure to install the power supplies and/or LED modules in accordance with the National Electric
Code (NEC), all applicable Federal, State and local electric codes as well as the specific Underwriters
Laboratories (UL) safety standards for the installation, location and application may cause serious
personal injury, death, property damage and/or product malfunction.
1. The LED module itself and all its components shall not be subjected to mechanical stress and assembly
must not damage or destroy conducting paths on the circuit board.
2. Observe correct electrical polarity, incorrect polarity may destroy the light engine. (Depending on the
product, incorrect polarity may lead to emission of red, or no light)
3. Electrostatic Discharge (ESD) precautions shall be incorporated when handling or installing the module.
4. Circuit boards should be attached securely to the intended substrate, but do not over-tighten screws or
rivets. Heavy vibration should be avoided.
5. The module itself is protected against condensation water with a polymeric conformal coating. Supplemen-
tary soldering on any solder pad will destroy the conformal coating and with it protection against water.
6. Modules may be hot to the touch. Use caution when handling.
Application Information
Application Notes
1. Single board add-ons are available to adjust length and fine tune light output.
2. The installation of the HF
2
Chain must include provisions for thermal management to obtain expected service
life. Service life (i.e. lumen maintenance) is primarily a function of LED temperature which is to be monitored
on the circuit board at the designated Tc point. A Tc point temperature of 40°C should be sufficient to enable
a service life of 50,000 hours.
3. The HF
2
Chain is designed with a metal core board which allows a 30,000 hour service life at a Tc point of
70°C.
4. There is no exact prescription to obtaining an appropriate Tc point temperature due to variations in fixture
designs. In general, the HF
2
Chain module should be adhered to a flat metal surface which has enough sur-
face area to transfer the heat from the LED module to the surrounding air. The metal surface can be part of
the mass of the sign itself.
5. The HF
2
Chain may be cut where boards are connected by red and black wires only.
6. For complete application information, see the HF Chain installation guide (LED054).

7. Loose wires at the end of the module must be capped off with UL Listed wire connectors.
8. Guidelines for proper UL 2108 installation:
– Definition of a UL 2108 listed Low Voltage Lighting System as it pertains to this module includes:
1. A UL Listed Class 2 power supply.
2. An appropriate number of SYLVANIA HF
2
Chain modules based on the
recommended max number of modules listed
3. Heat Sinks if applicable
– Power supply must be mounted, wired, and grounded in accordance with all applicable NEC and
ANSI standards.
– All modular connections on the secondary side of the power supply must be made using SYLVANIA
connectors. If additional wires and/or splice connectors are necessary, wires are to be UL Listed,
minimum 18 AWG, and connectors must be UL Listed, chosen of appropriate size for number of wires
to be connected.
– WARNING: The low voltage secondary circuit shall not be grounded.
This information shall not supersede the requirement to follow all other safety, assembly and any other
instructions listed in this document.
