Product Information

Achieve perfectly seamless linear lighting in the most confined spaces with SuperLightingLED narrow 2216 LED strip lights. This strip packs an impressive 240 LEDs per meter onto an exceptionally narrow PCB, available in 5mm, 4mm, and even 3mm widths. Unlike the standard 8mm/10mm 2216 strip, this model is engineered for discreet installation, delivering a flawless, dot-free line of light. Its high density and slim profile make it the ultimate solution for sophisticated architectural accents, detailed display cases, and minimalist under-cabinet lighting.

5mm white led strip lights

This strip is specifically designed to fit into the most compact LED aluminum profiles, ensuring a clean, professional finish where other strips simply won't fit. Powered by efficient 2216 SMD chips with 10W/m, it renders colors accurately and vividly, enhancing any environment.

Key Features

Exceptionally Narrow Profile

Available in 3mm, 4mm, and 5mm PCB widths, allowing installation in extremely tight grooves and channels.

High-Density & Dotless Output

With 240 LEDs/meter, it produces a smooth, continuous line of light with no visible hotspots, perfect for direct-view applications.

Versatile White Color Options

Choose from Warm White (3000K), Natural White (4000K), or Daylight White (6000K) to create the perfect ambiance.

Multiple Waterproof Ratings

Select from IP20 for dry indoor locations to fully submersible IP68 for pools, ponds, and outdoor water features.

Technical Highlights

  • Offers the same high density (240 LEDs/m) as wider 10mm strips but on a PCB as narrow as 3mm.
  • Precision cuttable every 25mm (0.98 inches) for exact length customization in detailed projects.
  • Operates on a stable and efficient DC 24V system, minimizing voltage drop compared to 12V strips.
  • Engineered for seamless lighting effects, especially when paired with a frosted diffuser.

Application Scenarios

Architectural & Cove Lighting The ultra-slim profile allows this strip to be embedded in narrow architectural reveals, tight coves, and custom millwork, creating stunning indirect lighting effects that appear to glow from within the structure.
Under-Cabinet & Task Lighting Install this high-density strip under kitchen cabinets, office shelves, or in workshop areas. Its dotless output provides bright, even, and shadow-free illumination perfect for detailed tasks.
Custom Linear Fixture Design A perfect choice for lighting designers and DIY enthusiasts building custom linear pendants or recessed fixtures. The combination of narrow width and high light output offers maximum design flexibility.

How to Install & Use This LED Strip

  1. Ensure the installation surface is clean, dry, and free of dust or oils.
  2. Measure and cut the strip to your desired length at the designated copper cut marks.
  3. Peel the adhesive backing and firmly press the strip onto the prepared surface.
  4. Connect the strip's wires to a compatible DC 24V power supply. For dimming, connect it to a single color dimmer between the strip and the power source.
  5. Connect the power supply to the main power source and test the lights.
⚠ Precautions
  • A compatible DC 24V power supply is required for operation. Ensure your power supply has at least 20% higher wattage capacity than the total load of the strip (e.g., a 60W power supply for a 50W roll).
  • For runs longer than 5 meters (16.4ft), power from both ends or use additional power feeds to avoid voltage drop and ensure consistent brightness.
  • Ensure the chosen waterproof rating matches the installation environment.

Frequently Asked Questions

Q: What makes this strip different from other 240 LEDs/m strips?

A:Its primary advantage is the ultra-narrow PCB, available in 3mm, 4mm, and 5mm widths. This allows it to fit into extremely tight spaces where standard 8mm or 10mm strips cannot.

Q: Will I see visible dots or hotspots with this strip?

A:Due to the very high density of 240 LEDs per meter, this strip provides a highly uniform, linear light output with minimal to no spotting, especially when installed in a channel with a diffuser.

Q: What power supply do I need for a full 5-meter roll?

A:The 5-meter roll consumes 50 Watts (10W/m x 5m). We recommend using a DC 24V power supply with a capacity of at least 60 Watts to ensure stable, long-term performance.

Q: Which PCB width should I choose?

A:Choose the width based on your installation constraints. The 5mm is a versatile standard narrow size, while the 4mm and 3mm options are for specialized applications with extreme space limitations.

Q: What is the difference between the IP67 Silicone Tube and Heat Shrink Tube options?

A:The Silicone Tube (IP67) is more flexible and easier to bend. The Transparent Heat Shrink Tube (IP67) provides a more rigid and snug protective layer. Both are rated for outdoor, wet locations but not for full submersion.

LED Strip Light Guide

Common questions about this type of product, answered against this model’s own options. For full figures see the specification above or the spec sheet for this model.

Which waterproof rating should I choose?
Available on this model: Outdoor Silicone Tube IP67 - Adhesive Back · Transparent Heat Shrink Tube IP67 · Underwater IP68 - Adhesive Back · Non-Waterproof IP20 - Adhesive Back. IP20 is for dry indoor use, IP65 handles splashes, IP67 suits outdoor and wet areas, IP68 is for continuous submersion. Choosing a waterproof rating
Can I cut it to length?
Yes. Cut only on the marked cut lines between the copper pads — the cut interval for this model is on its spec sheet. Rejoin with solder or a solderless connector. Cutting LED strip lights · we can also cut to length and fit your connector before shipping: custom LED strip light assembly.
What size power supply do I need?
Take the watts per metre from the specification above, multiply by the length you are running, then add about 25% headroom. Power calculation guide · Choosing a power supply
Which colour is right?
This model comes in Warm White(3000K) · Natural White(4000K) · Daylight White(6000K). Warmer whites suit living spaces, cooler whites suit task and display lighting. Screens do not show colour temperature accurately — order a sample if the room matters. Warm white vs cool white
Will it fit an aluminium profile, and how dense are the LEDs?
PCB width 3mm (0.12") · 4mm (0.157in) · 5mm (0.2in). Choose a profile whose inner width is at least the PCB width; denser LEDs give a smoother line close to a diffuser. LED aluminium profiles
