LIGHTING
General Information
» ALWAYS consult local codes before beginning a
project.
» Straight runs over 100' (30.5 m) may require larger
wire such as 16 or 14 gauge.
» USE TREX TRANSFORMER ONLY. Use of any
other transformer voids warranty.
Planning
NOTE: When designing your deck, plan locations of
lights, power supply, timer, and dimmer. These should
be accessible for service. Installing a GFCI outlet is highly
recommended to help prevent damage to lighting from
electrical surges.
1. The dimmer remote will work
in a 30' (9 m) radius of the unit.
2. Dimmer must be installed
in a dry location. Keep
dimmer remote ID # in a safe
place in case a replacement
remote is needed.
3. Timer must be installed vertically
with receptacle facing downwards
and not reaching ground level.
Timer must be in view of the sun to
use the dusk/dawn feature.
Installing Wiring
NOTE: It is recommended to install wiring before decking
and railing have been installed.
» Use 18 gauge stranded outdoor wire (available from
Trex) to connect wires from each light.
1. Wiring must be run
under decking structure
and behind stringers. DO
NOT run wires between
deck boards and joists.
Staple to frame with
cable staples at least
1 /4" (0.6 cm) wide.
DO NOT crush wire
insulation with staple.
2. Wiring can be run under deck and behind risers. Staple
to frame with cable staples at least 1/4" (0.6 cm) wide.
DO NOT crush wire insulation with staple.
3. Run wire up outside of each post that will have either
a post cap light or a deck rail light. Avoid running wire
on side of post where railing brackets or deck rail
lights will be installed. Leave a 6" (15.2 cm) loop at
top to make connections. Staple to frame and posts
with cable staples at least 1/4" (0.6 cm) wide.
DO NOT crush wire insulation with staple.
NOTE: After installing wiring, finish installing your Trex
decking and railing by following the Trex Installation
Guide.
Making Connections
» Polarity must be maintained through wiring system.
Always attach the same side of the 18 gauge wire to
red wires on the lights. Red wires are positive.
» Wire nuts supplied by Trex are gel-filled and
waterproof. These wire nuts can safely attach four
wires.
1. Strip wires to 5/8"
(1.6 cm). Align any
frayed strands of
conductors.
Pre-twisting is
unnecessary.
