Plan post cap lights, rail lights, stair and riser lights, recessed deck lights, under-deck lighting, transformer sizing, wire routing, and controls across Trex, TimberTech, and compatible outdoor lighting systems.
Lighting is cleanest when it is planned with railing, stairs, fascia, under-deck drainage, transformer sizing, and wire routing.
Trex lighting covers post cap lights, rail lights, stair riser lights, recessed deck lights, transformers, splitters, dimmers, timers, and WiFi controls.
TimberTech lighting should be part of the railing, stair, and deck-edge conversation on TimberTech projects so fixtures, colors, and wiring feel intentional.
If the deck has drainage underneath, lighting below the deck can turn the covered area into a real outdoor room instead of a dark storage zone.
A beautiful deck should not disappear when the sun goes down. The right lighting plan can combine post caps, rail accents, stair and riser lights, recessed deck lights, and under-deck fixtures so the whole outdoor space feels intentional after dark.
Low-voltage lighting still needs a real plan: fixture placement, transformer sizing, controller location, wire routing, railing compatibility, fascia details, and under-deck drainage all affect the final parts list.
Six categories of deck lighting — mix and match to create the perfect setup for your space.
The signature look. LED and solar options sit atop railing posts, casting a warm downward glow. Available in flat, pyramid, and aluminum styles to match any railing line.
Mount directly on railing posts to illuminate your deck's perimeter with a soft, even glow. Perfect for defining boundaries and adding depth.
Safety meets style. Mount into stair risers to illuminate each step — eliminating the number one cause of outdoor deck injuries after dark.
Flush-mount directly into your deck boards for a clean, seamless look. Perfect for lining pathways, perimeters, or creating accent patterns.
Zero wiring into the deck frame. Solar-powered post caps charge during the day and glow at night: the ultimate low-maintenance lighting option.
Smart control from your phone. Set schedules, dusk-to-dawn automation, timers, and dimming — all from the Trex app. The brain behind your lighting system.
LED deck lights provide warm, consistent light with lower energy use than older incandescent options. The right fixture mix keeps stairs, posts, and edges visible without over-lighting the space.
Trex LightHub® and other low-voltage lighting paths can simplify installation, but the parts still need to match the railing, deck layout, transformer, controller, and fixture count.
Most deck lighting systems use low-voltage components, which keeps the setup cleaner and easier to plan. Final installation requirements still depend on the project, local rules, and electrical details.
Optional WiFi Controller lets you manage everything from your phone. Set dusk-to-dawn schedules, create timers, and adjust brightness without leaving the couch.
Stairs, edges, and transitions become hazards after dark. Proper lighting eliminates tripping risks and makes your deck usable — and insurable — around the clock. Stair riser lights alone can prevent the most common outdoor injuries.
The right lighting turns a deck into an outdoor living room. Warm LEDs create the kind of atmosphere that keeps people outside longer — dinner parties, quiet evenings, late-night conversations. Your deck becomes a destination, not just a platform.
Outdoor lighting improves curb appeal and helps the deck feel like a finished outdoor room. It is a practical upgrade for evening use, especially when stairs, railings, patios, and under-deck areas are part of the layout.
A well-lit exterior is a natural deterrent. Illuminated decks, stairs, and perimeters make your home less attractive to unwanted visitors and give you visibility over your entire outdoor space.
Utah Deck Supply can help plan Trex lighting, TimberTech lighting, post cap lights, stair and riser lights, recessed deck lights, under-deck and soffit lighting, transformers, controllers, wire runs, and compatible finish details.
Start with the layout, not a fixture list. Decide what needs light: stairs, posts, perimeter boards, under-deck space, or rail accents. Then size the transformer, wire runs, splitters, and controls around that plan.
Warm white lighting is usually the safest choice for decks because it feels inviting without looking harsh or blue. Exact fixture color and brightness should be matched to the railing, stairs, patio, and surrounding exterior lights.
The most common starting points are post cap lights, stair or riser lights, and subtle perimeter lighting. Elevated decks may also need under-deck or soffit lighting so the space below feels finished and usable.
They should be planned early whenever possible. Transformer location, wire routes, post caps, stair details, fascia, and under-deck drainage are much easier to coordinate before the deck is closed in.
Often, yes. Some fixtures are designed around specific Trex or TimberTech systems, while post cap, riser, recessed, and under-deck lighting may work across multiple deck and railing setups. Bring photos or plans and we can help confirm the right path.
Tell us about your deck and we'll recommend the right lighting package: post caps, riser lights, recessed lights, under-deck lighting, transformer sizing, and wire runs.
