# Under Cabinet LED like a pro (no visible wires) Source: https://www.youtube.com/watch?v=KX32w8fOUII Recap page: https://rapidrecap.app/video/KX32w8fOUII Generated: 2025-12-24T16:03:56.943+00:00 --- ## Quick Overview The DIY project successfully installs hidden under-cabinet LED strip lighting that operates on a low-voltage circuit controlled by a custom-wired light switch and power supply, resulting in a clean, professional under-cabinet glow with no visible wires running along the exterior of the vanity. **Key Points:** - The installation uses a 24-gauge, two-wire LED strip light, which is routed through a drilled hole in the cabinet bottom from the outside corner to the center. - Power for the low-voltage LED circuit is derived by tapping into an existing outlet circuit using 14/2 electrical wire, routed through a junction box housing a transformer/power supply. - A custom switch setup is created by installing a dedicated light switch and a power supply/transformer inside a blue junction box hidden within the wall cavity. - The LED strip is secured to the bottom lip of the vanity kickplate using hot glue for a strong, long-term hold, ensuring the adhesive strips are supplemented for reliability. - The low-voltage wiring (24GA) connects the LED strip to the power supply, while the 14/2 electrical wire connects the power supply input to the new light switch circuit. - The final aesthetic is clean, as all electrical boxes and wiring are concealed inside the wall or cabinet, achieving the goal of 'no visible wires' outside the installation area (0:00, 2:15, 6:38). - The creator emphasizes that this method, which utilizes a switch to control power to the low-voltage transformer, is cheaper than using a smart switch or timer (4:28, 6:25). ![Screenshot at 0:01: The initial setup shows the finished vanity area with the newly installed, glowing LED strip lighting running along the bottom edge, demonstrating the desired 'under cabinet LED' result.](https://ss.rapidrecap.app/screens/KX32w8fOUII/00-00-01.jpg) **Context:** This video provides a detailed DIY tutorial on installing hidden, low-voltage LED strip lighting underneath a bathroom vanity to serve as subtle floor lighting, often referred to as toe-kick lighting. The creator outlines all necessary components, including 24-gauge wire for the LEDs, 14/2 electrical wire for the mains power connection, a power supply (transformer), a light switch, and a junction box for housing the electrical components inside the wall. ## Detailed Analysis The tutorial focuses on installing under-cabinet LED lighting that appears professional with no visible external wiring. The process begins by showing the required materials: 24GA wire (for LED power), 14/2 electrical wire (for mains power), an LED light strip, a power supply (transformer), a light switch, and a blue junction box (0:17). The first physical step involves cutting a hole in the drywall near the vanity base to install the junction box for the switch and power supply, which will source power from an existing outlet (0:35, 0:47). The creator drills a hole through the bottom of the vanity kickplate to pass the low-voltage wiring through (1:24). The 24GA wire is then run from the LED strip, through the hole, and into the cabinet space (1:26). The creator strips the wires of the LED strip and connects them to the 24GA wire using color-coded connectors (2:37). The LED strip is then carefully installed along the bottom front edge of the vanity kickplate, using hot glue in addition to the factory adhesive for a more secure, long-term attachment (2:58). On the electrical side, the existing outlet wires are disconnected, and the new light switch and the power supply wires are connected inside the wall junction box (4:02). The power supply's low-voltage output wires (white) are connected to the light switch terminals: one white wire to the terminal originating from the outlet (hot leg), and the other white wire to the neutral leg going back to the outlet (5:11). The black and red wires from the power supply connect directly to the LED strip (5:05). After securing the switch and outlet devices into their respective boxes and leveling them (5:51), the installation is complete, resulting in the illuminated toe-kick effect (0:01, 6:35). ### Materials & Preparation - Required parts include 24GA wire, 14/2 electrical wire, LED strip, power supply, light switch, and a junction box - Preparation involved cutting a hole in the wall for the junction box and drilling a hole in the toe-kick for wire passage (0:17, 0:47) ### LED Strip Installation - The 24GA wire is fed from inside the cabinet to the end of the LED strip and connected using connectors (2:29) - The LED strip is mounted along the bottom edge of the vanity kickplate, secured with hot glue for extra hold despite the existing adhesive (2:58) ### Electrical Wiring - Power is sourced by tapping the existing outlet circuit - The power supply/transformer is wired into the new switch circuit inside a wall junction box (4:02) - The 24GA wire from the LED strip is routed through the cabinet hole and connected to the low-voltage side of the power supply (1:30) ### Switch and Power Connections - The hot leg from the outlet connects to one terminal of the light switch, and the neutral leg connects to the other side of the power supply output (5:11) - The second white wire from the power supply output connects to the neutral line going back to the outlet (5:19) ### Final Assembly and Result - All electrical components are secured inside their respective junction boxes and leveled (5:27, 5:51) - The final product shows soft, hidden under-cabinet lighting controlled by the new switch (6:35) ![Screenshot at 0:01: The finished under-cabinet lighting installation providing a warm glow along the light-colored wood floor.](https://ss.rapidrecap.app/screens/KX32w8fOUII/00-00-01.jpg) ![Screenshot at 0:17: All necessary components displayed on the floor, including 24GA wire, 14/2 electrical wire, LED strip, power supply, switch, and work box.](https://ss.rapidrecap.app/screens/KX32w8fOUII/00-00-17.jpg) ![Screenshot at 0:35: The creator uses a level to mark and cut a hole in the drywall to install a new junction box for the switch and power supply.](https://ss.rapidrecap.app/screens/KX32w8fOUII/00-00-35.jpg) ![Screenshot at 2:30: Close-up view of the creator feeding the 24GA wire through a drilled hole in the vanity kickplate to connect to the LED strip.](https://ss.rapidrecap.app/screens/KX32w8fOUII/00-02-30.jpg) ![Screenshot at 4:02: The creator manipulates the wiring inside the blue junction box, connecting the 14/2 wire from the outlet circuit to the light switch and power supply.](https://ss.rapidrecap.app/screens/KX32w8fOUII/00-04-02.jpg)
