Measure and cut Tetra LED
strip to the appropriate length
for each letter. Cuts can be
made between any of the
modules.
2
Use the double stick tape or
electrical grade RTV silicone
to fix LED module within the
channel letter.
4
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.

Do not use connectors pre-filled with silicone grease/mineral base protective grease or use silicone grease to seal connections.
Cap wires
Optional:
Cut wires flush
Must cap all exposed wires with appropriate wire

Optional:
Cut wires flush to the module and seal with
electrical grade RTV silicone.
