Product Information
Achieve flawless, high-density linear lighting in the most compact spaces with our 3mm Super Narrow Single Color LED Strip Light. Engineered with an incredibly slim 3mm PCB, this is one of our narrowest flexible strips, making it the ultimate solution for intricate designs, tight channels, and edge-lit applications where standard strips simply won't fit.
It features a high density of 180 LEDs per meter, ensuring a smooth, uniform glow with minimal spotting. With a superior Color Rendering Index (CRI) of over 90, it illuminates objects in their true, vibrant colors. Customize your project by choosing between premium SMD2216 or efficient SMD2022 LED chips, and select from three distinct white color temperatures.
Key Features
Ultra-Narrow 3mm Profile
Our slimmest design fits into tight grooves, sharp angles, and miniature profiles for discreet, built-in lighting effects.
High-Density Illumination
Packed with 180 LEDs per meter, this strip produces a smooth, continuous line of light with reduced hot spots.
Dual LED Chip Options
Choose the premium performance of SMD2216 chips or the excellent value of SMD2022 chips to suit your project's budget and needs.
Please Note: The SMD2216 chip option has a minimum order quantity of 20 meters (4 rolls) due to material availability.
Versatile White Tones
Available in Warm White (3000K), Natural White (4000K), and Daylight White (6000K) to create the perfect ambiance.
Customizable Waterproofing
Select from non-waterproof IP20 or two distinct IP67 ratings (slim heat-shrink tube or robust silicone tube) for protection in any environment.

How to Install & Use This LED Strip
- Ensure the installation surface is clean, dry, and free of dust or oils.
- If needed, cut the strip to your desired length only at the designated copper cut marks.
- Connect the strip's 2-pin wires to a compatible single color dimmer or directly to a DC24V power supply. How to wire white led strip lights?
- Peel the protective backing from the adhesive tape and firmly press the strip onto the prepared surface.
-
Connect the power supply to your main power source to light up the strip.

- A compatible DC24V power supply is required (sold separately). Ensure its wattage is at least 20% higher than the strip's total power consumption (48W or greater recommended for a full 5m roll).
- For assistance choosing a power supply, see our guides: How to calculate power for led strip lights? and How to choose led strip light power supply?
Frequently Asked Questions
Q: What makes this LED strip 'super narrow'?
A:This strip is built on a 3mm wide flexible printed circuit board (PCB), making it one of the thinnest LED strips available and ideal for installation in extremely tight spaces.
Q: What is the difference between the SMD2216 and SMD2022 LED chips?
A:SMD2216 is a premium, smaller LED chip known for its high efficiency and excellent color rendering, making it a professional choice. SMD2022 is a highly efficient alternative that offers great performance and value.
Q: Is there a minimum order quantity for the SMD2216 version?
A:Yes, due to special material requirements, the SMD2216 chip option has a minimum order quantity of 20 meters, which is equivalent to 4 rolls of this strip.
Q: What is the difference between the two IP67 waterproof options?
A:The Heat Shrink Tube option provides a very tight, slim waterproof seal that adds minimal bulk. The Outdoor Silicone Tube is a more robust, slightly larger sleeve that offers enhanced durability for more demanding outdoor environments.
Q: What kind of power supply do I need for a full 5-meter roll?
A:A full 5-meter roll consumes 40W. We recommend using a DC24V power supply with a capacity of at least 48W (40W x 1.2) to ensure stable performance and longevity.
