How To Install Deck Rail Lighting

Transforming your deck into a cozy nighttime retreat is easier than you might think. With the right lighting, you can create an inviting ambiance that extends outdoor chill time well into the evening hours. Deck rail lighting provides both aesthetic appeal and practical illumination. In this video, Ask This Old House master electrician Heath Eastman demonstrates how to turn a dark deck into a welcoming hangout spot after sunset. The guide below will help you install deck rail lighting yourself.

What Is Undermount Lighting for a Deck?

Undermount lighting is a popular choice for deck illumination due to its subtle yet effective nature. It can provide light for the deck and illuminate areas where you might be walking. It’s also very easy to conceal.

Heath walks through the process of installing waterproof strip lights and shows how to make them last longer in the outdoors. He shows how to protect the lights from the elements by using mounting channels to put the lights in and heat shrink tubes to protect wire connections.

Assessing Your Deck’s Layout

Before you begin your lighting installation project, assess the current layout and condition of your deck. Consider the following:

• Deck dimensions: Measure the length and width to determine the quantity of lighting needed.
• Obstructions: Identify any features, such as posts or railings, that may affect light placement.
• Existing lighting: Note any existing lights or electrical access points that can be integrated with the new setup.

Once you understand your deck’s layout, you can make well-informed decisions on where to install the lighting for optimal effect.

Choosing the Right Deck Rail Lighting

Selecting the appropriate lighting for your deck is key to achieving the desired outcome. These factors can help inform your choice:

• Waterproof rating: Opt for lights with an IP67 rating or higher to withstand outdoor conditions. The IP67 rating means that the lights can withstand temporary submersion in water, which is suitable for the rain and windy conditions the lights might encounter on your deck.
• Color temperature: Choose between warm white (2700K-3000K) for a cozy atmosphere or cool white (4000K-6500K) for brighter illumination. You can also choose color-changing or multicolor lights.
• Power source: Decide between hardwired or solar-powered options based on your deck’s location and electrical access. With a hardwired option, you won’t need to worry about having power, while a solar option offers flexibility to be installed almost anywhere.
• Brightness: Select lights with adequate lumens for your space, typically 100-200 lumens per foot for deck railing.

For this project, Eastman uses 3′ White LED Landscape Strip Lights with a 12VAC power supply and IP67 waterproof rating manufactured by SuperBrightLEDs. These lights strike a balance between brightness and energy efficiency. Eastman also suggests making sure that the lights you select are UL-rated.

Materials and Tools Needed To Install Deck Rail Lighting

Before starting the installation, gather the necessary materials and tools to ensure a smooth process:

Materials

• LED waterproof strip lights
• Mounting track
• Alcohol wipes
• Landscape wiring
• Brass barrel connectors
• Shrink tube
• Staples
• Wire clips

Tools

• Power drill
• Heat gun
• Hammer
• Lineman’s pliers
• Measuring tape
• Wire stripper
• Screwdriver
• Utility knife

Having all the required items on hand before beginning the project helps avoid interruptions during installation.

Preparing for Installation

Inspect the Deck

Check the deck railing for signs of wear or damage before starting. Repair or replace any damaged sections to ensure a secure mounting surface for the lights.

Plan Light Placement

Use a measuring tape to mark where the LED strips will go. Eastman recommends setting the lights 1½ inches from the edge to keep them hidden from view.

Test the Lights

Before permanently installing the lights, connect them to the power source and test their functionality. This step ensures that all components are working correctly.

Step-by-Step Installation Process

Installing deck rail lighting can be accomplished in a few hours with the right approach. These are the steps Heath takes to install deck rail lighting:

1. Locate the nearest power source: This determines the complexity of running cables to your deck lights. Heath uses an existing outlet near the deck, but you may need to install a new receptacle if one isn’t available nearby. This will drive up the time and cost required to do the project.
2. Measure and mark: Decide how far back you want the lights to be set. Heath recommends 1½ inches from the edge to keep the strips hidden from view.
3. Mount the track: Secure the mounting track under the railing using screws and a power drill.
4. Clean the surface: Use alcohol wipes to clean the mounting track, ensuring better adhesion for the LED strips.
5. Apply the LED strips: Carefully stick the strip along the mounting track, working slowly to avoid air bubbles or misalignment.
6. Make connections: Connect the LED strips using the provided connectors or soldering if required.
7. Conceal wiring: Tuck excess wires out of sight and staple them to the surface where necessary.
8. Install the feed wire: Two wires should be left unconnected for the feed wire, somewhere central to all the strip lights. You don’t want to connect them all together because you will have the potential of the lights dimming towards the end because of voltage drop.
9. Run power to the lights: Connect a wire from the power source to the LED lights.
10. Secure connections: Use brass barrel connectors to join the lights to the power wire, covering each connection with heat shrink tubing for weather protection.
11. Apply heat: Use a heat gun to shrink the tubing around the connections, ensuring a watertight seal.
12. Hide and secure all wiring: Conceal and fasten any visible wires for a clean, professional look.

By following these steps, you can achieve a polished and functional deck lighting system that enhances your outdoor living space.

Additional Lighting Enhancement Ideas

While undermount lighting provides a wonderful glow, you can add even more lighting enhancements to further elevate your deck’s ambiance:

• Post cap lights: Install lights on top of deck posts for added height and visual interest.
• String lights: Drape string lights overhead or along railings for a festive atmosphere.
• Step lights: Illuminate stairs with built-in lights for improved safety and aesthetics.

Combining different lighting styles can create a layered and captivating effect on your deck.

Tips for Maintaining Your Deck Rail Lighting

To ensure your new deck rail lighting continues to shine bright for years to come, consider these maintenance tips:

• Regularly inspect connections for signs of wear or water damage
• Clean the LED strips periodically with a damp cloth to remove dirt and debris
• Check for loose mounting tracks or strips and re-secure as needed
• Replace any damaged sections of lighting promptly to prevent further issues
• Consider applying a clear silicone sealant over connections for added protection

With proper care, your deck rail lighting can provide long-lasting illumination and enjoyment.
