Product Information

Create stunning lighting effects where traditional strips won't fit with our Side Emitting LED Strip Light. This flexible 16.4ft (5-meter) strip features 300 reliable 335 SMD light-emitting diodes that project light parallel to the mounting surface, rather than perpendicular. This unique design makes it the ultimate solution for edge lighting, illuminating signage, backlighting acrylic panels, and creating clean halo effects in tight spaces. Engineered for versatility, this standard-density strip is available in four distinct shades of white, two low-voltage options (5VDC and 12VDC), and your choice of non-waterproof IP20 for indoor projects or a splash-resistant IP65 coating for added durability in kitchens and bathrooms (IP67 and IP68 are also available).

Application Scenarios

Signage and Retail Displays Ideal for edge-lighting acrylic signs, logos, and product displays. The side-firing light creates a crisp, uniform halo effect that makes lettering and graphics pop, grabbing customer attention.
Under-Cabinet and Shelf Illumination Mount the strip on the interior front edge of cabinets or shelves. The light projects horizontally across the surface, providing excellent task lighting on countertops or showcasing items on a shelf without visible diodes.
Custom Vehicle and Marine Accents The flexible design and low-voltage 12V/5V DC options are perfect for creating custom interior accent lighting in cars, RVs, and boats. Tuck it into panel gaps, under dashboards, or along trim pieces for a unique glow.  

How to Install & Use This LED Strip

  1. Ensure the mounting surface is clean, dry, and free of dust or oils.
  2. Measure and cut the strip at the designated copper cut marks to achieve your desired length.
  3. Connect the strip's wires to a compatible 5V or 12V DC power supply. For dimming, wire a single color dimmer between the power supply and the strip.
  4. Peel the protective layer off the adhesive backing.
  5. Firmly press the strip onto the prepared surface, ensuring full contact along its length.

⚠ Precautions
  • Always use a power supply that matches the strip's voltage (5V or 12V). Using the wrong voltage will permanently damage the strip.
  • Do not bend the strip tighter than its recommended minimum bend radius to avoid damaging the circuit.
  • For long-term reliability, especially with the IP20 version, consider mounting in an aluminum channel for better heat dissipation.
  • Be aware of potential LED voltage drop on runs longer than 5 meters; plan your wiring accordingly to maintain consistent brightness.

Frequently Asked Questions

Q: What is a 'side-emitting' LED strip?

A:Unlike standard strips where light shines up from the surface, a side-emitting strip has LEDs mounted on their edge, causing light to project out parallel to the mounting surface. This is perfect for edge-lighting applications.

Q: What is the difference between the 5V and 12V versions?

A:The 12V version is the most common for general lighting and can handle longer runs with less voltage drop. The 5V version is ideal for smaller projects or applications where you want to use a USB power source or battery pack.

Q: What is the difference between IP20 and IP65 waterproof ratings?

A:IP20 is non-waterproof and should only be used in dry, indoor locations. The IP65 version has a clear silicone coating that protects it from dust and low-pressure water jets, making it suitable for kitchens, bathrooms, or sign exteriors.

Q: How bright is this strip compared to other models?

A:This strip features a standard density of 60 LEDs per meter, offering a great balance of brightness and energy efficiency for most accent lighting, task lighting, and decorative applications.

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.

What voltage does this LED strip light run on?
This model is offered in 5VDC · 12VDC. Lower voltage means a shorter run per feed: at 12 V feed power roughly every 5 m, at 24 V roughly every 10 m. Longer runs get power injected at both ends. Connecting to the power supply
Which waterproof rating should I choose?
Available on this model: Surface Glued IP65 - 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 8mm (0.31in). 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
