Product Information

Unlock precision lighting possibilities with the our narrowest 3528 LED strip. Engineered with an ultra-slim 3.5mm-3.6mm wide PCB, this flexible strip is the ultimate solution for installations in tight channels, intricate designs, and applications where standard strips are too bulky. It features a high density of 480 high-performance 3528 SMD LEDs across a 16.4ft (5m) roll, delivering a smooth and consistent line of light. Available in a diverse palette of nine vibrant static colors, from warm white to cool white and vivid primaries, this strip offers versatile options for any project. 

Key Features

Ultra-Narrow 3.5mm PCB

Our thinnest 3528 strip, designed to fit into the most confined spaces, slim profiles, and detailed custom projects. Combine with an LED aluminum channel for a professional, diffused look.

Dense & Smooth Illumination

Features 96 LEDs per meter (480 LEDs per 5m roll), minimizing spotting and creating a clean, uniform line of light.

Precisely Cuttable

Can be cut every 3 LEDs (31.25mm) along the marked lines, allowing for perfect customization to any length. 

Optional IP67 Waterproofing

Available in non-waterproof IP20 or two IP67-rated versions for reliable performance in damp or outdoor locations.

Ideal for Precision Lighting Applications

Architectural Accents & Cove Lighting The ultra-slim 3.5mm profile allows this strip to be seamlessly integrated into tight architectural reveals, narrow coves, and minimalist designs. Use it for edge-lit signs, under-shelf lighting, and creating subtle glows where larger strips won't fit.
DIY & Hobbyist Projects An excellent choice for model makers, custom PC builders, and creative enthusiasts. Its miniature size and flexibility make it easy to incorporate detailed lighting into dioramas, scale models, and unique electronic projects. 

How to Install & Use This LED Strip

  1. Ensure the installation surface is clean, dry, and free of dust or oils.
  2. Measure the required length and carefully cut the strip along the designated copper cut marks.
  3. Connect the strip to a compatible DC12V power supply. For dimming, connect it through a controller from our Single Color Dimmer Series
  4. For IP20 and IP67 versions, peel the adhesive backing and firmly press the strip onto the surface. 
  5. Connect the power supply to your power source to light up the strip.

⚠ Precautions
  • Always use a regulated DC12V power supply. Using a higher voltage will destroy the strip. We recommend a power supply with at least 20% higher capacity than the strip's total power requirement. How to choose led strip light power supply?

What's in the Box

  • 1 x 16.4ft (5m) Roll of Super Narrow 3.5mm 3528 LED Strip Light
  • Your selected LED Controller (if 'Strips + Controller' or 'Full Kit' option is chosen). The default is V1 + RT1.
  • Your selected DC12V Power Adapter (if 'Strips + Power Adapter' or 'Full Kit' option is chosen). The default indoor power supply is PSPS-12V-48W

Frequently Asked Questions

Q: What makes this LED strip 'super narrow'?

A:Its Printed Circuit Board (PCB) is only 3.5mm wide, which is significantly thinner than standard 8mm or 10mm strips. This allows it to be installed in very tight grooves, channels, and intricate designs.

Q: What do I need to power a full 16.4ft roll?

A:You will need a DC12V power supply. The full roll consumes 40 watts (8W/m x 5m), so we recommend a power supply with a capacity of at least 48 watts to ensure stable performance.

Q: What is the difference between the two IP67 waterproof options?

A:Both offer excellent protection against water and dust. The Transparent Heat Shrink Tube is a slimmer profile, while the Outdoor Silicone Tube is slightly more robust and includes a 3M adhesive backing for easier installation.

Q: How do I dim this LED strip?

A:This strip is fully dimmable from 0-100%. To control the brightness, you will need to connect it to a compatible single-color LED dimmer or controller between the strip and the power supply.

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 Pink · Yellow(585-595nm) · Blue(465-475nm) · Green(515-525nm) · Red(620-630nm) · Cool White(7000K). 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
