Read on to learn about the different types of lighting you can install to complement your new deck, then start building inspiration around deck lighting ideas to brighten your space.

Keep the Future of Your Deck Bright With Upfront Installation

Even if you don’t want deck lighting right now, it’s important to pull the wires to keep the option open for future enhancements — wiring your deck for lighting at the onset will keep the installation much easier down the road. While installation will vary based on the type of lighting you choose, there are still some important considerations and safety precautions to keep in mind:

  • Turn off/unplug all wiring during installation.
  • Do not operate a luminaire fitting with a missing or damaged cover.
  • Building codes vary by locale, so please consult all applicable codes before beginning a project.
  • Modifications must be made to railing components during assembly to accommodate wiring and fixtures. For lighting that involves railing, be sure to read all lighting instructions carefully before assembling.
  • A maximum of 40 watts can be applied to a single circuit, and no more than 90 watts should be applied to the transformer. Please refer to the chart below for the wattage of each fixture.
  • The 16AWG secondary supply wire can be buried to a maximum of 6 inches for routing under deck or other obstacles. The luminary (unit secondary) wires cannot be buried underground.
Accent2 watts
Mini Accent1 watt
In-Deck1 watt
Lighted Island Cap2 watts
Post Cap Light4 watts
Stair Riser2 watts
Under Rail2 watts

For the installation of TimberTech lighting, you will need the following, in addition to a basic tool set:

  • Spade bits: 5/8-inch, 3/4-inch, 1-inch
  • Allen wrench: 2.5 millimeter
  • Drill bits: 3/8-inch, 7/64-inch, 1/4-inch
