What is a side-emitting LED strip?

A side-emitting or side-view LED strip has LEDs that shine light parallel to the strip's surface, not upwards. This makes it ideal for lighting edges, profiles, and creating indirect lighting effects where the strip itself is hidden from view.

Can I cut this LED strip to a custom length?

Yes, the strip is designed to be cut. The 12V version can be cut every 3 LEDs, and the 24V version can be cut every 6 LEDs, at the clearly marked copper cut points.

What is the difference between IP20, IP65, IP67, and IP68 waterproof ratings?

IP20 is for indoor, dry use only. IP65 has a silicone coating for protection against dust and low-pressure water jets. IP67 uses a silicone tube for better protection and can be temporarily submerged. IP68 is fully encapsulated for continuous underwater use. This model is available in IP20 and IP65.

Product Information

Create stunning, indirect lighting effects with our High-density Side Emitting LED Strip Light. Unlike traditional strips, this design features 335 SMD light-emitting diodes mounted to project light parallel to the surface, making it perfect for edge-lighting signs, backlighting panels, and creating subtle glows in architectural coves. With a high density of 600 LEDs per 16.4ft reel (120 LEDs/m), this strip produces a remarkably uniform and continuous line of light with minimal spotting. Its slim 8mm profile allows for installation in tight and narrow spaces. Available in multiple white color temperatures and a specialized UV wavelength, with options for a 12VDC or 24VDC system and IP65 waterproofing, this versatile light emitting strip is engineered for creative and professional lighting projects. IP67 outdoor version is also available.

Key Features

High-Density Side-Emitting Design

Features 120 LEDs per meter, where the led emitting light sideways for a smooth, dot-free glow ideal for edge-lighting and indirect illumination.

Versatile Lighting Options

Choose from three shades of white (3000K, 4000K, 6000K) or a specialized UV (395-405nm) light for unique applications. Solid colors are also available.

Dual Voltage & Waterproofing

Select between 12VDC and 24VDC to match your system's needs, with an optional IP65 surface-glued coating for protection against dust and moisture.

Slim & Flexible Profile

The 8mm wide PCB is easy to bend and install in narrow channels, tight corners, and intricate designs where space is limited.

Application Scenarios

Signage & Display Lighting Perfect for edge-lighting engraved acrylic signs or backlighting display cases. The side-firing LEDs create a brilliant halo effect that makes letters and graphics pop, providing clear and uniform light emitting diode display.

Under Cabinet & Task Lighting When installed along the front edge of shelving or under cabinets, this strip directs light backward across the surface, reducing glare and providing excellent task illumination for countertops and workspaces.

Specialty UV Applications The optional UV (395-405nm) version is ideal for fluorescent effect displays, counterfeit detection, resin curing, or creating unique atmospheres in entertainment venues and themed environments.

How to Install & Use This LED Strip

Clean the installation surface to ensure it is dry and free of dust and oils.
Measure the required length and cut the strip at the designated copper solder pads. The 12V version can be cut every 3 LEDs, and the 24V version every 6 LEDs.
Peel the backing from the adhesive tape and firmly press the strip onto the surface.
Connect the strip's wires to a compatible 12V or 24V power supply. Ensure the voltage matches your strip version. For dimming, connect a LED dimmer between the power supply and the strip.
Power on the system to test the connection and enjoy your new lighting.

⚠ Precautions

Always use a power supply that matches the strip's voltage (12VDC or 24VDC). Using the wrong voltage will damage the strip.
For long runs, be aware of potential voltage drop. Powering from both ends or using thicker gauge wire may be necessary.
The IP20 version should only be used in dry, indoor locations. The IP65 version is resistant to splashes but should not be submerged.
Ensure adequate heat dissipation, especially in enclosed spaces, to maintain the strip's lifespan.

Frequently Asked Questions

Q: What is the benefit of having 120 LEDs per meter?

A:This high density of LEDs creates a more uniform and continuous line of light, significantly reducing the 'spotting' or 'dot' effect seen on lower-density strips. This is crucial for professional-looking installations where the light source is reflected or visible.

Q: What kind of power supply do I need?

A:You need a power supply that matches your strip's voltage (12V or 24V). To calculate the wattage, multiply the strip's length in meters by 9.6W/m and add 20% for overhead (e.g., a 5m reel needs 5m * 9.6W/m * 1.2 = 57.6W). So, a 60W or higher 12V/24V power supply is recommended.

Q: What is the UV light option used for?

A:The 395-405nm UV-A light is a 'blacklight' that can be used for creating fluorescent effects with reactive materials, curing certain resins and adhesives, or for inspection and verification purposes in various industries.

My go-to store for any LED project

This must be my fifth or sixth order from SuperLightingLED over the last few years and the quality is ALWAYS consistent. I had a quick question about whether this side-emitting strip would be suitable for a very narrow channel I was using for some accent lighting. Violet got back to me in a few hours, which is amazing considering the time difference with China, and confirmed the specs for me. Shipping to the US was ridiculously fast again, I don't know how they do it. The warm white color is spot on and the strips work perfectly. It’s this kind of service and reliability that keeps me coming back instead of trying my luck elsewhere.

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 24VDC · 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 UV(395-405nm) · 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
