Thinnest LED Strip Manufacturer
As a global leader in miniaturized lighting solutions, ADLED specializes in developing the thinnest LED strip technology for architects, designers, and innovators. Our R&D team pioneers ultra-compact formats like 3mm LED strip, micro LED tape, and ultra thin COB LED strip, setting industry benchmarks for slimness, flexibility, and performance. Whether you need small LED light strips for wearables or super thin ribbon LED strips for luxury interiors, we engineer the world’s most advanced thinnest LED light strip systems — all ISO-certified, RoHS-compliant, and backed by 5+ years of lighting expertise.

What Is the Thinnest LED Strip?
The thinnest LED strip refers to an ultra-compact, flexible lighting tape — typically 3mm LED light strips wide — that uses COB (Chip-on-Board) technology to eliminate visible diodes. Unlike conventional 10mm or 12mm strips, our thinnest LED strip lights measure only 3mm, making them ideal as very thin LED strip, micro LED strip, or super thin LED strips for discreet applications. This category includes ultra thin LED tape, ultra thin LED ribbon, and thin COB LED strip variants, all designed for seamless integration. Whether called smallest LED strip lights or LED strip slim thin, they share one goal: invisible brilliance.

Thinnest LED Strip Application
At only 3mm wide, these ultra thin LED light strips unlock applications previously impossible with standard 5–12mm LED strips:
- Home: TV backlighting, under-cabinet, stairs, mirrors
- Retail: Shelf lighting, display cases, signage (ultra thin LED ribbon)
- Automotive: Dashboards, footwells, trim accents
- Architecture: Cove, handrails, minimalist facades
- DIY & Tech: Wearables, robotics, smart furniture (small LED light strips)
- Marine/RV: Low-profile, vibration-resistant (very thin LED strip)
Wherever space is limited, our thin COB LED strip delivers maximum impact.

Connectable LED Strip Lights

- The maximum running length is 1 meter. For installations over 1 meter, please connect the LED strips in parallel.
- Ensure that the total wattage of the COB thinnest LED strip lights does not exceed 80% of the power supply’s maximum output.
- When connecting, match the polarities according to the markings ('+' and '-') on the PCB.
