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.

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.

Measure and cut Tetra LED
strip to the appropriate length
for each letter. Cuts can be
made between any of the
modules.

Drill a 1/4-inch (6.4 mm)
hole near the LED strip and
grommet the hole for supply
wire access.
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

after 24 hours. Continue until you
have reached the end of the strip.
Remove all the debris from the
inside of the channel letter and
