Planning and Pre-Wiring

Early in the home construction, before wallboards are installed, the system’s wiring layout is planned. The installer collaborates with the builder and trim carpenter to ensure that wiring accommodations are integrated during the structural phase of building. During the rough-in stage, wires are run from the planned transformer location to each window, maintaining a layout that balances the load across various zones of the house.

Installation of Mounting Clips

Post-window installation and prior to homeowner possession, mounting clips are installed at each window. These clips serve as the anchors for the decorative bases and the candle assemblies. Installers place mounting clips on the windowsills using the pre-planned locations. Wires are run through these clips, and connections are made using wire locks and screws. Care is taken to ensure that the copper prongs on the clips properly pierce the wire insulation to make a secure electrical contact.

Final Setup & Homeowner Instruction

After the homeowner takes possession of the property, the final installation of candlesticks and decorative bases is carried out. The system is then tested in the presence of the homeowner, who is also instructed on the operation and maintenance of the lighting system. Before finalizing the installation, the system is tested for electrical continuity and proper operation. Any issues, such as wire shorts caused by nails or improper fittings, are addressed. Candlesticks and decorative bases are installed, and the entire system is tested to confirm full functionality. The homeowner is given a demonstration of the system’s operation, including how to replace bulbs and handle the system's controls.

Safety Precautions

The installation must comply with local electrical codes and NEC Class 2 wiring standards. Installers are advised to consult local regulations and possibly employ a licensed electrical contractor. Homeowners are advised on how to maintain the system and whom to contact for troubleshooting and support. This includes instructions on safely removing and replacing components of the system and contact information for technical support.

What do I need for a system?

To start, you'll need our official WindowCandles UL listed wire to run from window to window in order to power the candles. You'll then need to think about how many candles you'll need for however many windows you have.

Something that people forget is that LED bulbs use 90% less energy than incandescent, so picking the bulbs that are right for you is key. See the chart below for help with choosing the number of transformers you'll need.

In order to mount the candles, you need the WCA1 kit that includes all mounting hardware, a candle, and a generic 302-C incandescent bulb.

Once you have the bare-bones system working with wire, a transformer, mounting clips, and candles, you can now start thinking about which of our 10,000 different design combinations you'll choose by browsing our caps, sleeves, bases, bulbs, and more!
