Benefits of Trex Deck Lighting

Trex deck lighting utilizes energy-efficient LED technology, which consumes significantly less power than traditional incandescent or halogen bulbs. This translates to lower energy bills and a reduced carbon footprint.

Trex lights are built to last, made from weatherproof materials designed to withstand the elements. This means you can enjoy your illuminated deck for years to come without worrying about frequent replacements or repairs.

Trex lighting options are designed to blend seamlessly with your deck’s design, enhancing its visual appeal. From subtle accents to bold focal points, there’s a Trex light for every style.

Types of Trex Deck Lighting

Post Cap Lights

These lights are mounted on top of deck posts, providing a gentle glow that outlines the perimeter of your deck. They are available in a variety of styles and finishes to match your deck’s aesthetic.

Recessed Deck Lights

Recessed deck lights are installed flush with the deck surface, creating a sleek, modern look. They are perfect for illuminating walkways, seating areas, and other key features of your deck.

Stair Riser Lights

Stair riser lights are installed on the vertical face of each step, enhancing visibility and safety while adding a touch of elegance to your deck’s staircase.

Under-Rail Lights

These lights are mounted beneath the railing, casting a soft glow on the deck surface below. They provide subtle, ambient lighting without detracting from your deck’s overall design.

Installation Process

Before installing your Trex deck lighting, it’s essential to create a plan. Determine the locations of each light fixture and measure the distances between them. This will help you calculate the amount of wiring and other materials needed for a smooth installation.

Trex deck lighting uses a low-voltage wiring system, which is both safer and easier to install than traditional electrical systems. Run the wiring from your transformer to each light fixture, taking care to conceal the wires beneath the deck boards or behind the railing for a clean, polished appearance.

Follow the manufacturer’s instructions for mounting your chosen Trex light fixtures. Ensure that each light is securely fastened and positioned correctly for optimal illumination and visual appeal.

To keep your Trex deck lighting looking its best, clean the fixtures regularly with a soft cloth and mild soapy water. Avoid using harsh chemicals or abrasive materials, as they may damage the finish.

Periodically inspect your deck lighting system for signs of wear or damage. Check the wiring, connections, and fixtures to ensure everything is in good working order.

Replacing Bulbs

Although Trex LED lights are designed to last for many years, they may eventually need to be replaced. Follow the manufacturer’s instructions for replacing the LED bulbs to maintain the efficiency and brightness of your deck lighting.

Integrating Smart Technology

Consider integrating smart technology with your Trex deck lighting for added convenience and control. Options like smart switches, dimmers, and timers can help you customize your lighting preferences and save energy.

Trex Deck Lighting Accessories

Trex offers a range of accessories to complement your deck lighting systems, such as remote controls, dimmers, and extension cables. These accessories can enhance the functionality and ease of use of your lighting system.

Design Ideas

For a contemporary look, combine recessed deck lights with under-rail lights to create clean lines and a minimalist feel. Choose fixtures with sleek, modern designs and finishes.


To achieve a rustic vibe, opt for post-cap lights with a warm, vintage-inspired appearance. Pair them with stair riser lights to create a cozy, inviting atmosphere.

Multi-level Deck

If you have a multi-level deck, use a combination of lighting types to accentuate each level and create a sense of depth. Mix stair riser lights, recessed deck lights, and post cap lights to highlight the different layers of your deck.
