A Sign Maker's Guide to Choosing LED Modules for Channel Letters and Light Boxes

What Is an LED Module?

An LED module is a compact unit containing multiple light-emitting diodes arranged on a circuit board and packaged with waterproofing or lens treatments. Unlike loose LEDs, modules arrive ready to mount, wire, and power. They are designed specifically for signage applications such as channel letters, light boxes, sign cabinets, and logos.

Key Factors When Choosing LED Modules

Brightness and Efficiency

Look for modules that deliver enough lumens for the sign face material and depth. High-efficiency modules reduce power consumption and heat while maintaining uniform illumination. HansonLed offers high-efficiency options including 0.72W, 1.2W, 1.5W, and 2W modules to match different brightness requirements.

IP Rating

Indoor signs may only need IP20 protection, while outdoor channel letters and light boxes require IP65, IP67, or IP68 rated modules. HansonLed's IP67 and IP68 series use robust encapsulation to withstand rain, dust, and temperature swings.

Beam Angle and Lens Design

The beam angle determines how light spreads inside a letter or box. Narrow beams work for deep channels, while wide angles suit shallow signs. Black dot lens modules and edge-lit modules provide specialized light distribution for unique sign geometries.

Voltage

Common options include 12V, 24V, and high-voltage AC modules. Low-voltage systems are safer for installers and easier to control, while high-voltage modules simplify long runs by reducing voltage drop. HansonLed supplies 12V, 24V, and AC 110V/220V modules.

Color and CRI

White modules come in warm white, natural white, and cool white. RGB and RGBW modules enable color-changing effects for retail and architectural projects. For applications where color accuracy matters, choose modules with high CRI.

Types of LED Modules for Signage

Channel Letter LED Modules

Designed for face-lit and back-lit channel letters, channel letter led module products provide focused output and compact sizes. Options include mini modules for narrow strokes and high-efficiency modules for large letters.

Light Box LED Modules

Light box modules deliver wide, even illumination across large surfaces. Backlight modules and rigid bars are commonly used for fabric light boxes, menu boards, and airport signage.

Mini LED Modules

When sign faces are small or strokes are thin, mini LED modules fit where standard modules cannot. They are ideal for small channel letters and detailed logos.

High Voltage LED Modules

AC 110V/220V modules eliminate the need for large power supplies in some installations, making them popular for large-scale projects and regions where low-voltage drivers are less convenient.

RGB and Pixel LED Modules

For dynamic signage, RGB and addressable pixel modules create color-changing, animated effects controlled by compatible drivers.
