Introduction
Cabinet lighting transforms a functional kitchen or living space into a premium, well-appointed environment. Whether you're illuminating a countertop workspace, showcasing dishware behind glass doors, or adding ambiance to a display cabinet, the right lighting system makes all the difference. This guide covers everything you need to plan and specify a complete cabinet lighting solution — from fixture types to power supplies, controllers, and system design.
References throughout this guide draw from the Tresco by Rev-A-Shelf lighting system, a leading modular LED platform designed specifically for cabinetry applications.
Types of Cabinet Lighting & Applications
Under-Cabinet Lighting
The most common and impactful cabinet lighting application. Fixtures mount to the underside of upper cabinets to illuminate the countertop workspace below.
- Best for: Kitchen task lighting, prep areas, coffee stations, bathroom vanities
- Fixture types used: LED strip lights, linear bars, puck lights
- Key considerations: Color temperature (2700K–3000K for warm kitchens; 4000K for task-focused spaces), CRI 90+ for accurate food and material color rendering, even distribution without hot spots
In-Cabinet / Interior Cabinet Lighting
Lighting installed inside cabinet interiors to illuminate contents — glassware, dishware, collectibles, or pantry shelving.
- Best for: Glass-front cabinets, display cabinets, pantries, linen closets
- Fixture types used: Puck lights, LED strip lights along cabinet perimeter or shelves
- Key considerations: Door-activated switching (lights on when door opens, off when closed), low heat output to protect contents, compact form factor
Above-Cabinet / Top-of-Cabinet Lighting
Uplighting placed on top of upper cabinets to wash light across the ceiling, creating ambient depth and visual height.
- Best for: Kitchen ambiance, accent lighting, open-concept spaces
- Fixture types used: LED strip lights, flexible ribbon lights
- Key considerations: Warm color temperature for ambiance (2200K–2700K), low-profile installation, often dimmer-controlled
Toe-Kick Lighting
LED strip or bar lights installed in the toe kick recess at the base of lower cabinets. Creates a floating effect and improves nighttime navigation.
- Best for: Kitchen, bathroom, hallway accent lighting; nightlight applications
- Fixture types used: LED strip lights, low-profile linear bars
- Key considerations: Durable, moisture-resistant fixtures; motion-sensor or dimmer control for nightlight use
Shelf Lighting
Edge or surface-mounted lighting along shelving to highlight items on display. Often used in open shelving, wine racks, and floating shelf installations.
- Best for: Open shelving, wine storage, display niches, retail-style product presentation
- Fixture types used: LED strip profiles, recessed puck lights, edge-lit shelf panels
- Key considerations: Slim profile to minimize visual intrusion, color temperature matched to display items
Drawer & Interior Accent Lighting
Small puck or strip lights inside drawers or behind doors that activate on open. Practical and premium-feeling — especially in knife drawers, spice pull-outs, and jewelry organizers.
- Best for: Deep drawers, pull-out organizers, bedroom cabinetry, closets
- Fixture types used: Tresco Puck Lights, magnetic-mount mini fixtures
- Key considerations: Motion or door-switch activation, battery or hardwired options
Lighting Components
LED Strip Lights
Flexible ribbon-style lights with surface-mount LEDs spaced at regular intervals. The backbone of most modern cabinet lighting systems.
- Available in single-color (white), tunable white (adjustable color temp), and RGB/RGBW (color-changing)
- Measured in lumens per foot or meter — higher lumen output = brighter
- Cut points allow customization to exact cabinet dimensions
- Tresco's LinkLight™ system uses tool-free connectors for modular strip installation without soldering
Puck Lights
Circular, disc-shaped fixtures that provide a focused pool of light. Easy to install and available in surface-mount or recessed versions.
- Ideal for interior cabinet illumination and accent applications
- Available in hardwired and plug-in versions
- Tresco puck lights are available in multiple diameters and finishes to blend with cabinetry
Linear Bar Lights
Rigid aluminum fixture bars with integrated LEDs, often with a frosted diffuser for even light distribution. More uniform output than puck lights.
- Available in fixed lengths or cut-to-length profiles
- Ideal for under-cabinet task lighting where even, shadow-free illumination is required
- Tresco's Blaze™ series offers integrated aluminum bar lights with interchangeable components
Recessed Lights
Small fixtures installed flush into cabinet shelving, panels, or undersides. Provide a clean, furniture-grade appearance.
- Require a boring hole or routed recess for installation
- Ideal for high-end display cabinets and custom millwork
Tape/Ribbon Light with Aluminum Channel Profiles
LED strip lights installed inside extruded aluminum channels with diffuser covers. The channel protects the strip, manages heat, and diffuses the light to eliminate visible LED dots.
- Available in surface-mount, recessed, corner, and pendant profile shapes
- Dramatically improves light quality and installation durability
- Strongly recommended for any exposed or semi-exposed strip light installation
Power Supplies
All low-voltage LED cabinet lighting systems require a driver or power supply to convert line voltage (120V AC) to the operating voltage of the LEDs (typically 12V DC or 24V DC).
Hardwired Drivers (LED Drivers)
- Mounted inside the cabinet, above the ceiling, or in a dedicated power location
- Sized by total wattage of connected fixtures — always add 20% headroom (e.g., if fixtures total 40W, use a 50W+ driver)
- Tresco's ELV (Electronic Low Voltage) drivers are compatible with most trailing-edge dimmers for smooth dimming performance
- Available in 12V and 24V output; match to your fixture voltage — mixing voltages will damage fixtures
Plug-In Power Supplies
- Plug directly into a standard outlet; ideal for retrofit or rental installations
- Lower cost and simpler installation; limited by outlet proximity
- Not recommended for finished cabinetry where cords would be visible
Wattage Planning
Calculate total system wattage before selecting a driver:
- Sum the wattage of all fixtures in the circuit
- Multiply by 1.2 for a 20% safety margin
- Select a driver rated at or above that number
- For large installations, split across multiple drivers rather than running one oversized unit
Tresco Tip: Tresco's modular power supply ecosystem (12V and 24V drivers, plug-in transformers, and junction boxes) is designed to integrate directly with their LinkLight™ and Blaze™ product lines, simplifying system planning and reducing field wiring errors.
Controllers & Switching
On/Off Switches
Basic rocker or touch switches that control the entire lighting circuit. Often installed inside the cabinet run or at a convenient wall location.
Dimmer Switches
Allow brightness adjustment for mood, task, and ambiance needs. Critical considerations:
- Must be LED-compatible (look for ELV or MLV rating)
- Match dimmer to driver type — Tresco ELV drivers require trailing-edge (ELV) dimmers
- Avoid leading-edge (TRIAC) dimmers with LED drivers unless specifically rated — can cause flicker, hum, or reduced lifespan
Door-Activated Switches
Magnetic or mechanical switches that turn lights on when a cabinet door opens and off when it closes. Standard in interior cabinet lighting applications.
- Tresco door switches are surface-mount and compatible with their puck and strip systems
- Available in normally-open (NO) and normally-closed (NC) configurations
Motion Sensors
PIR (passive infrared) sensors that activate lights when motion is detected. Ideal for toe-kick nightlights, closets, and pantries.
- Adjustable sensitivity and auto-off timers
- Low-voltage versions integrate directly into LED driver circuits
Smart / Wireless Controllers
RF or Bluetooth controllers that allow app-based or remote control of color temperature, brightness, and color (for RGB systems).
- Tresco's wireless dimming system uses RF remotes and receivers that mount inside the cabinet — no wall switch wiring required
- Ideal for retrofit installations where running new switch wiring is impractical
- Enables scene setting and scheduling on compatible systems
Tunable White Controllers
Allow adjustment of color temperature between warm white and cool white (e.g., 2700K–6500K). Useful in kitchen and bath environments where lighting needs shift between morning, day, and evening use.
System Design Tips
- Plan your voltage first — choose 12V or 24V and stick with it throughout the system. 24V systems support longer run lengths without voltage drop.
- Use aluminum channel profiles for any exposed strip light run to improve aesthetics, heat management, and longevity.
- Wire in zones — separate upper cabinets, lower cabinets, and interior lighting onto dedicated circuits for independent control.
- Label your drivers — especially in larger installations with multiple power supplies.
- Test before finishing — power up the full system before closing up cabinetry or installing trim.
- Check local electrical code — hardwired low-voltage systems may require a licensed electrician depending on jurisdiction.
