Lightkiwi's hardwire under cabinet lighting kits let you connect LED under cabinet lights directly to your home's wiring — no outlet, no visible cords, no power supply plugged into a cabinet. Each kit includes a dimmable transformer compatible with standard magnetic low voltage wall dimmer switches, giving you clean, professional-grade dimming control from any wall switch.
What's Included in a Hardwire Kit?
Each Lightkiwi hardwire kit includes everything needed for a complete direct-wire install: a dimmable LED driver/transformer (50W or 100W), LED under cabinet light panels, and all necessary wiring harnesses. The transformer steps down your home's 120V line voltage to the 24V required by the LED panels, while the built-in dimming circuit works seamlessly with a magnetic low voltage wall dimmer (sold separately).
Hardwire vs. Plug-In Under Cabinet Lighting
Plug-in kits are easier to install but leave a visible cord and require an outlet inside or near the cabinet. Hardwire kits connect directly to your home's electrical wiring for a completely cord-free, built-in look — ideal for new construction, kitchen remodels, or anywhere a clean finish is a priority. Hardwire installs are permanent and typically require a licensed electrician for the line-voltage connection.
Wall Dimmer Switch Compatibility
Lightkiwi hardwire kits are designed to work with magnetic low voltage (MLV) wall dimmer switches — the type required for LED drivers that use magnetic transformer technology. Do not use electronic low voltage (ELV) or standard incandescent dimmers, as these are incompatible and may cause flickering or damage. Popular compatible dimmers include Lutron and Leviton MLV models.
Frequently Asked Questions
Do I need an electrician to install a hardwire under cabinet lighting kit?
For the line-voltage (120V) wiring connection, yes — NEC code requires a licensed electrician for hardwired installations in most jurisdictions. The low-voltage side (connecting panels to the driver) can typically be done by a homeowner.
What wall dimmer switch works with Lightkiwi hardwire kits?
You need a magnetic low voltage (MLV) wall dimmer switch. Common compatible options include the Lutron Skylark MSCELV and Leviton IPL06 series. Standard incandescent or ELV dimmers will not work correctly.
What is the difference between 50W and 100W hardwire kits?
The wattage refers to the maximum load the driver can handle. The 50W kit works for smaller installs (typically up to 4–5 panels), while the 100W kit supports larger runs (up to 8–10 panels). Choose based on the total wattage of the panels you plan to install.
Can hardwire under cabinet lights be dimmed?
Yes. Lightkiwi hardwire kits include a dimmable driver that works with a compatible magnetic low voltage wall dimmer switch for smooth, flicker-free dimming from 0–100%.
