Measure and cut Tetra LED strip
to the appropriate length for
each letter. Cuts can be made
between any of the modules.
Use rivets, screws, or electrical
grade RTV silicone to secure
at least every fifth LED module
within the channel letter. Use #6
(M3) pan headed metal screws,
1/8-inch (3.2 mm) rivets, or
electrical grade RTV silicone.
Before you begin, clean surfaces
and remove all debris from the
inside of the channel letter.Clean
the surfaces with a 50:50 mixture
of isopropyl alcohol (IPA) and
water and let dry.
Layout Modules
Drill a 1/4-inch (6.4 mm) hole
near the LED strip and grommet
the hole for supply wire access.
Remove all the debris from the
inside of the channel letter and
replace the sign face.
NOTE: For halo-lit applications LED modules should be mounted on UL
recognized clear acrylic or polycarbonate. The light output from the LED
system should be directed back into the sign enclosure. This will allow for
uniform backlighting of the sign and will provide simple mounting.
Remove tape backing and stick LED
modules into place. When using
tape apply approximately 15 psi
pressure on the module (avoid the
lens dome surface) for 5 seconds,
full bonding strength after 24 hours.
Continue until you have reached the
end of the strip.

Seal all connections in wet locations with electrical
grade RTV silicone.
Must cap all exposed wires with appropriate wire
connectors and seal with electrical grade RTV silicone.
Optional: Cut wires flush to the module and seal with
electrical grade RTV silicone.
