What are the Benefits of Deck Lighting?

Deck lighting has a number of benefits. Most importantly, deck lighting increases safety and also allows you to use your deck when it’s dark out. Trex lighting is hardwired and has a long lifespan, so once it’s installed you can trust it to work when you need it. 

Deck lighting also serves as a design choice that enhances what you love about your deck, with options to suit both modern and classic deck looks. Whatever style you choose, Trex’s deck lights can be used to highlight decorative features and create distinct zones on your deck.

Let’s take a closer look at a couple of the key benefits of deck lighting from Trex.


Deck lighting enhances safety in a few important ways. Stair riser lights, for example, minimize the risk of anyone tripping in the dark. In contrast, recessed deck lighting can be used to guide people along pathways or provide general diffuse light that makes the deck surface, and its edges, visible. Similarly, post caps or railing lights gently light the whole deck area and, if they're angled downwards, provide a clear indication of the structure’s zones.

Controlling your lights remotely, as you can using Trex's WiFi controller, allows you to keep your home safe, too. Turn your outdoor lights on in the evenings to create the impression that someone is home, even if you’re on a beach hundreds of miles away!

Easy Installation

The new Trex Solar Post Cap Light is our easiest lighting to install. With the click of a button and a little sunlight, you are on your way to a well-light outdoor space. Installing wired Trex deck lighting is straightforward and a keen DIY-er should be able to get them set up and switched on in a few hours. If you’re not the handy type or simply want to save time by hiring a professional to install deck lighting it will be a quick job for them.

Improved Technology

The functionality of outdoor lighting, specifically deck lighting, has improved significantly in the last few years, as have the tools for designing your deck lighting – for example, you can use Trex’s deck lighting calculator to plan the technical details of your deck lights set-up. 

Additionally, LEDs are now almost ubiquitous, meaning a longer lifespan for every one of your deck lights. Far from the bright-white glare of the past, LED lighting offers a warm and gentle glow. You can even control the brightness from anywhere using Trex's app-based WiFi controller when using our wired lighting options. The app’s advanced features also allow you to set lighting schedules and monitor lighting status, which means no more worrying about whether or not you left the porch lights on. As all Trex plug-and-play lighting options are already compatible with the controller, it’s easy to add it to your existing lighting set-up. Just install your controller between your power supply and your lights, download the Bond Home app, and you’re good to go. For Trex Solar Post Cap Light users, the set-up is even easier. Turn your post cap on with the button inside each cap, and you're set; no app or WiFi controller needed. These handy lights can sense the lighting in your backyard and will automatically turn on and off accordingly.
