What Is LED Under Cabinet Lighting?

LED under cabinet lighting refers to linear fixtures installed beneath upper cabinets to provide task lighting for countertops. Unlike traditional puck lights or fluorescent tubes, modern LED solutions like our UC Series offer superior energy efficiency, long lifespan, and versatile installation options.

Key Specifications Every Buyer Should Know

1. Color Rendering Index (CRI)

CRI measures how accurately colors appear under artificial light. For kitchen applications, always specify CRI90+ under cabinet lights for premium results. The UC Series delivers CRI90+ across all six models, ensuring granite countertops, backsplash tiles, and food colors appear vibrant and true-to-life.

2. Color Temperature (CCT) Selection

Traditional approach requires stocking 5 separate SKUs for different color temperatures. Our patented 5CCT selectable technology allows end-users to choose their preferred temperature (2700K/3000K/3500K/4000K/5000K) via slide switch—reducing your inventory by 80% while giving customers complete flexibility.

3. Installation Methods

The UC Series supports three installation methods to fit any project:

• Hardwired: 3/8″ knock-out holes (1/2″ available upon request) for clean, permanent installation
• Plug-in: Quick-connect for DIY-friendly projects
• Linkable: End-to-end or cable jumper connections, up to 50 units per run

Conclusion
