Measure and cut Tetra LED
strip to the appropriate
length for each letter. Cuts
can be made between any of
the modules.
Use the double stick tape or
electrical grade RTV silicone
to fix LED module within the
channel letter.
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.
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
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.
