How to Install LED Strip Lights Behind a Mirror

Adding LED strip lights behind a mirror creates a sophisticated and modern ambiance in any room, from bathrooms and bedrooms to living areas. This illuminating effect not only enhances the aesthetic appeal of the mirror but also provides practical task lighting. This guide outlines the steps involved in installing LED strip lights behind a mirror safely and effectively.

Planning and Preparation

Careful planning is crucial for a successful installation. Begin by measuring the perimeter of the mirror to determine the required length of the LED strip. LED strips are typically sold in rolls and can be cut to specific lengths at designated cut points. Account for any corners or curves the strip needs to navigate. Consider the desired brightness and color temperature of the LEDs. Warm white creates a cozy atmosphere, while cool white provides a brighter, more invigorating light. Choose LEDs with a high CRI (Color Rendering Index) for accurate color representation, particularly important in bathrooms where applying makeup is a common activity.

Next, select the appropriate power supply. The power supply should match the voltage and amperage requirements of the chosen LED strip. The strip's packaging will specify these requirements. It is recommended to choose a power supply with slightly higher amperage than the strip requires to avoid overloading it. Also, consider the location of the power supply and how it will be connected to the mains electricity. A qualified electrician should perform any electrical work if you are not comfortable working with electricity yourself.

Finally, gather the necessary tools and materials. These typically include the LED strip, power supply, connecting wires, wire connectors, mounting clips, scissors or a utility knife (for cutting the LED strip), a measuring tape, and a level.

Mounting the LED Strip

Before mounting the LED strip, ensure the surface behind the mirror is clean and dry. Dust and debris can interfere with the adhesive backing of the strip. Most LED strips come with a self-adhesive backing. If yours does not, consider using double-sided tape specifically designed for mounting LED strips. Peel back a small section of the adhesive backing and carefully align the strip along the edge of the mirror, pressing firmly as you go. Ensure the strip is straight and follows the desired path. For curved mirrors, gently bend the strip to conform to the shape. Avoid sharp bends as this can damage the internal circuitry.

At corners, carefully fold the strip, ensuring not to crease or damage it. Utilize corner connectors if provided or recommended for your specific LED strip type. These connectors create a seamless transition and eliminate the risk of damaging the strip during bending. Continue attaching the LED strip along the perimeter of the mirror until the entire length is secured.

For added security, especially in humid environments like bathrooms, use mounting clips in conjunction with the adhesive backing. These clips provide extra support and prevent the strip from peeling over time due to moisture or temperature fluctuations. Space the clips evenly along the length of the strip.

Wiring and Power Connection

With the LED strip securely mounted, the next step is to connect the wiring. If the LED strip requires cutting, ensure to cut only at designated cut points, usually marked with scissors icons on the strip. Connect the LED strip to the connecting wires using the appropriate connectors. Ensure the polarity is correct; LED strips have positive (+) and negative (-) terminals that must be matched with the corresponding wires. Use wire connectors to secure the connections and provide insulation.

Connect the other ends of the connecting wires to the power supply, again ensuring correct polarity. Consult the power supply’s instructions for specific wiring guidance. Before connecting the power supply to the mains electricity, double-check all connections to ensure they are secure and properly insulated.

Once all connections are verified, connect the power supply to the mains electricity. Test the LED strip to ensure it is functioning correctly. If the strip does not light up, double-check the power supply connection, the connections between the strip and the wires, and the polarity of the connections. If issues persist, consult a qualified electrician.

Finishing Touches and Safety Precautions

Conceal the wiring and power supply as much as possible to maintain a clean and professional appearance. Depending on the mirror and its mounting, you might be able to hide the wires and power supply behind the mirror itself or within the wall cavity. Consult a professional for any modifications involving electrical wiring within the wall.

Always prioritize safety when working with electricity. Ensure the power supply is compatible with the LED strip and the local electrical code. Never overload the power supply. If you are unsure about any aspect of the installation, consult a qualified electrician.
