Installing led strip lights under cabinets is one of the most effective ways to brighten your kitchen, workspace, or display area. It adds elegant task lighting and creates a clean, modern atmosphere. If you’re working with a 110V power supply, you’ll need to install your LED strips safely and correctly.
There are two main types of LED strips that can work with 110V input:
Direct 110V LED strip lights – Designed with a built-in rectifier and driver, allowing direct connection to the wall outlet.
Low-Voltage LED Strips (12V or 24V) – Require a power supply (transformer) to convert 110V AC to DC before installation.
For safety and versatility, most under-cabinet lighting uses 12V or 24V LED strips powered by a DC driver. Direct 110V strips are used for longer runs or commercial applications.
LED strip light (12V, 24V, or 110V model)
Power supply / driver (if not integrated)
Mounting clips or aluminum channel with diffuser
110V plug or hardwired connection
Wire connectors and electrical tape
Measuring tape and scissors
Cleaning cloth and alcohol wipes
Screwdriver or drill (for mounting)
KEYFINE LED provides complete under-cabinet kits with compatible power supplies and accessories for both residential and commercial use.
Determine the exact length of your cabinet area and plan where the strip will start and end. Consider where your 110V outlet or junction box is located.
Tip: It’s best to hide the power supply and wiring inside or behind the cabinet for a clean finish.
Use alcohol wipes or a damp cloth to clean the underside of the cabinet. Dust or grease can prevent the adhesive backing from sticking firmly.
Allow the surface to dry completely before installing the LED strip.
If you’re using low-voltage LED strips, cut them along the designated cut lines marked on the strip.
Then, attach connectors or solder wires to link multiple sections together.
For 110V LED strips, cut only where indicated by the manufacturer — typically every 0.5 m or 1 m, depending on the model.
Peel off the adhesive backing and apply the LED strip under the cabinet.
Press firmly along the entire length to ensure secure adhesion.
For a more professional finish, use KEYFINE LED aluminum channels or mounting clips. These not only keep the strip in place but also help with heat dissipation and light diffusion.
If using a low-voltage LED strip:
Connect the strip’s DC wire to the power supply output (matching + and –).
Plug the power supply into your 110V outlet.
If using a 110V LED strip:
Connect the strip’s input wire directly to the wall plug or junction box using the provided connector.
Ensure all connections are insulated properly to prevent electric shock.
Safety Note: Always switch off power before connecting wires. For hardwired installations, consult a licensed electrician.
Turn the power on to test brightness and color consistency.
If the strip doesn’t light up, double-check:
Polarity alignment (+/–)
Secure wire connections
Power supply output voltage
Tidy up cables using clips or cable sleeves.
Install a dimmer switch, motion sensor, or remote control for convenience.
KEYFINE LED provides a full range of smart control options, including Wi-Fi, Bluetooth, and touch dimmers for under-cabinet lighting.
Avoid overlapping LED strips, as this can cause overheating.
Choose warm white (2700K–3000K) for kitchens or cool white (4000K–6000K) for workspaces.
Use waterproof strips (IP65) if near sinks or humid areas.
Install aluminum channels to hide wiring and extend LED lifespan.
Consider diffusion covers to achieve uniform, glare-free light.
