Can I cut this LED strip to a custom length?

Yes, this 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. Look for the designated copper cut marks on the strip.

What is the main difference between the 12V and 24V versions?

The 24V version can be run in longer continuous lengths than the 12V version before experiencing voltage drop (dimming at the far end). For shorter runs (under 16ft), 12V is fine. For longer installations, 24V is recommended.

Do I need a controller for this strip?

To simply turn the strip on and off, you only need a matching 12V or 24V power supply. If you wish to adjust the brightness (dimming), you will need to add a single color dimmer between the power supply and the strip.

What is the difference between IP20 and IP65 waterproof ratings?

IP20 Non-waterproof is for indoor, dry locations only. IP65 Waterproof has a silicone coating that protects against dust and low-pressure water jets (splashes), making it suitable for kitchens or bathrooms, but not for submersion. This product is not available in IP67 or IP68 ratings.

Product Information

Create stunning, indirect lighting effects with our Solid Color Side Glow LED Strip Light. This unique strip features 335 SMD LEDs that emit light from the edge, making it the perfect solution for sign delineation, edge-lighting acrylic panels, or creating a subtle halo glow around objects. With a high density of 120 LEDs per meter, this glow led light strip produces a smooth, uniform line of light with minimal spotting. Available in multiple vibrant colors—from crisp Cool White to rich Red and Ice Blue—and your choice of 12V or 24V operation, it offers versatile design possibilities for both commercial displays and creative home projects. The slim 8mm PCB allows for installation in tight spaces where traditional lighting won't fit.

Key Features

Side-Emitting Light Source

LEDs are mounted to project light parallel to the mounting surface, ideal for edge-lighting and indirect accent illumination.

High-Density & Uniform Glow

Packed with 120 LEDs per meter, this strip creates a continuous and even line of light, minimizing hot spots for a professional finish.

Vibrant Color Options

Choose from various distinct colors, including two shades of cool white, plus yellow, ice blue, blue, green, and red to match any design theme.

Flexible & Customizable

The flexible 8mm wide PCB can be cut every 3 LEDs (12V) or 6 LEDs (24V) for precise length adjustments to fit your project perfectly.

Versatile Configurations

Available in both 12VDC and 24VDC, with options for IP20 non-waterproof or IP65 surface-glued waterproof ratings to suit indoor applications.

Application Scenarios

Architectural Accent & Edge Lighting Trace the contours of walls, ceilings, bars, and reception desks. The side-firing LEDs are perfect for tucking into small reveals or mounting along the edge of panels to create a sharp, clean line of light.

Retail & Signage Illumination Make your displays and signage pop. Use this strip to edge-light acrylic signs or back-light logos for a professional halo effect that draws customer attention without visible bulbs.

Mirror & Vanity Backlighting Create a modern, high-end look for bathroom lights on side of mirror installations. The side glow provides even, diffuse light that reduces shadows, making it perfect for vanities and dressing rooms.

How to Install & Use This LED Strip

1. Surface Preparation: Clean the mounting surface thoroughly to ensure it is dry and free of dust, oils, or waxes for optimal adhesion.
2. Cut to Size (If Needed): Measure the required length and carefully cut the strip along the designated copper cut marks.
3. Connection: If you cut the strip, you will need to solder wires or use 2-pin connectors to connect the segments to your power source. Ensure you match the polarity (+ and -).
4. Power Up: Connect the strip to an appropriate 12V or 24V DC power supply. To control brightness, wire a compatible single color dimmer between the power supply and the strip.
5. Mounting: Peel the protective backing off the adhesive tape and press the strip firmly onto the prepared surface.

⚠ Precautions

Always use a power supply with a wattage rating at least 20% higher than the strip's total power consumption to avoid overloading.

The 24V version is recommended for longer continuous runs to minimize voltage drop.

Frequently Asked Questions

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

A:A side-emitting LED strip has LEDs that shine light from the edge of the strip, parallel to the mounting surface. This is different from standard strips where the light shines directly upwards, away from the surface.

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

A:A higher LED density like 120 LEDs/m creates a more uniform and continuous line of light, significantly reducing the visible dots or 'hotspots' seen in lower-density strips. This results in a smoother, more professional lighting effect.

Q: What kind of power supply do I need for a full 16.4ft reel?

A:The full 5-meter reel consumes 48 watts. We recommend a power supply with at least 20% higher capacity, so a 60W power supply (12V or 24V, depending on your strip version) would be ideal.

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: Outdoor Silicone Tube IP67 - Adhesive Back · Underwater IP68 - Adhesive Back · 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 Amber (1800K) · Green · Ice Blue · Pink · Cool White (9000K-10000K) · 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

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
