Quick Answer

This 6500K Single White LED Module (XXA-MODULE-7515-W-12V) is a compact, cuttable LED module string designed for signage, light boxes, and channel letter applications. Each module measures 75 × 15 × 4mm with 3 × SMD2835 LEDs, operates at DC12V (0.72W), and comes with 2-pin waterproof M/F connectors. The string contains 20 modules and supports individual cutting.

This module was supplied for Darren's custom Character Head signage project — where the 6500K color temperature was specifically selected to match the colors of the portrait sign.

As a flexible customization product, key parameters — including wire length, connector type, and module quantity — can be tailored to specific project requirements.

Key Features

1. High Brightness 6500K White – Clean, Crisp Illumination

The 6500K color temperature produces a bright, cool white light — ideal for:

  • Retail signage and storefronts

  • LED light boxes

  • Channel letters

  • Commercial displays

The 160° beam angle ensures wide, even light distribution across the sign face.

2. 3 × SMD2835 LEDs – Efficient and Reliable

Each module uses 3 × SMD2835 LEDs, a widely used chip known for:

  • High luminous efficacy

  • Low lumen depreciation

  • Consistent color output

3. Individual Cutting – Flexible String Configuration

The string contains 20 modules and can be cut individually. This allows:

  • Custom string lengths per project

  • Precise fitting into channel letters of different sizes

  • Reduced waste — use only what you need

Recommendation: Each set of modules should not exceed 40 modules per series. Exceeding this may cause heat buildup and reduced brightness. For multiple modules, use parallel circuit wiring.

Suitable for both indoor and outdoor signage applications.

5. 3M Adhesive Backing – Easy Installation

Each module features 3M back adhesive for:

  • Firm, secure mounting

  • Easy peel-and-stick installation

  • No additional hardware required

6. Pure Copper Flexible Wire – Heat Resistant

The modules use pure copper extra flexible wire that is:

  • High-temperature resistant

  • Environmentally safe

  • Durable for long-term installations

7. Waterproof M/F Connectors – Simple Daisy-Chaining

The 2-pin waterproof male/female connectors allow:

  • Easy connection between strings

  • Simple daisy-chaining for extended runs

  • Reliable signal and power transmission

Frequently Asked Questions

1. What is a single-color LED module?

A single-color LED module is a sealed lighting unit containing one or more LED chips that emit a fixed color — typically warm white, neutral white, or cool white. Unlike RGB or addressable modules, single-color modules do not change color; they provide consistent, uniform illumination for a specific application.

Single-color modules are commonly used in:

  • Channel letters and backlit signage

  • Light boxes and menu boards

  • Backlighting for acrylic or fabric faces

  • Architectural accent lighting

They are available in different color temperatures (e.g., 3000K, 4000K, 6500K), power ratings, and waterproof levels (IP65, IP67) to suit indoor and outdoor installations.

2. What is a backlit illuminated sign?

A backlit illuminated sign is a signage system where the light source is positioned behind the sign face, illuminating the graphic or text from the rear. The light passes through a translucent face material — such as acrylic, polycarbonate, or fabric — creating a soft, even glow.

Backlit signs are used for:

  • Retail storefronts and shopping malls

  • Corporate reception areas

  • Menu boards and directional signage

  • Exhibition and trade show displays

The two most common backlit configurations are:

  • Light box signs — a hollow box with LEDs mounted inside, illuminating a printed face

  • Backlit channel letters — individual letters with LEDs behind a translucent face

Single-color LED modules are the standard light source for most backlit signage because they deliver consistent brightness and uniform color across the sign face.

3. Why do backlit signs use single-color modules instead of RGB?

Backlit signage is designed to display a fixed graphic or brand identity — not to change colors dynamically. Single-color modules are preferred for three reasons:

  1. Uniformity — A single color temperature across all modules ensures the sign face looks consistent, with no color variation between sections.

  2. Simplicity — No controller or addressing is required. The modules connect directly to a DC power supply, reducing system cost and installation complexity.

  3. Reliability — Fewer components mean fewer potential failure points. Single-color modules typically have a longer lifespan and lower maintenance requirements than addressable alternatives.

RGB or addressable modules are used when the sign needs dynamic color effects — such as animated displays or color-changing brand elements. For standard backlit signage, single-color is the practical choice.

4. What should I check when selecting modules for a backlit sign?

When specifying single-color modules for a backlit sign, verify the following:

Parameter

What to Check

Color Temperature

Match to brand guidelines (3000K warm / 4000K neutral / 6500K cool)

Brightness

Lumens per module must suit the sign depth and face material

Beam Angle

Wide angle (160°+) for even illumination

IP Rating

IP65 minimum for outdoor; IP20 for indoor dry locations

Module Spacing

Determined by sign depth and desired uniformity

Power Supply

DC12V or DC24V — match to module voltage

Connector Type

Waterproof M/F for outdoor; standard for indoor

Rule of thumb: For backlit signs, use modules with a wide beam angle and consistent binning (MacAdam ≤3-step) to avoid visible color differences across the face.

5. How many modules do I need for a backlit sign?

The number of modules depends on three factors:

  1. Sign area — larger signs require more modules

  2. Sign depth — deeper signs need higher output or more modules to maintain brightness at the face

  3. Desired brightness — retail and outdoor signs typically require higher luminance than indoor corporate signage

A practical starting point:

  • Small signs (≤0.5m²): 10–20 modules per square meter

  • Medium signs (0.5–2m²): 20–30 modules per square meter

  • Large signs (≥2m²): 30–40 modules per square meter

Always confirm with a photometric calculation or request a layout recommendation from your module supplier. Overloading a single power supply can cause voltage drop and uneven brightness — use parallel wiring and multiple power feeds for larger installations.
