Light emitting diode (LED) modules are self-contained devices housing a chain of LED emitters. Perfect for channel letters, narrow profiles and advertising displays, they come in three sizes—small, standard and large—offering a choice of colours, brightness levels and beam angles.

In this guide we introduce WeLoveLEDs’ small, standard and large LED modules, outline their key differences, and point you to expert advice.

Small LED modules

Small modules fit narrow profiles and shallow built-ups—ideal for slim channel lettering, cove lighting or intimate event décor. They offer efficiency, low heat and long life.

Browse all small sizes in our Small LED Modules collection.

For colour options beyond white, consider our ROCK RGBW LED Module, which combines RGB control with an extra white chip for pastel and crisp shades.

See our Expert Guide to Small LED Modules for in-depth information.

Standard LED modules

Standard modules balance output and size, perfect for halo illumination, backlighting or decorative luminaires. They’re available in pure white, warm white, RGB/RGBW and single colours.

Explore standard sizes in the LED Modules collection.

A popular choice is the ROCK1 LED Module, which offers wide beam angles, integrated heat sinking and IP65 protection for reliable outdoor use.

Large LED modules

Large modules provide high output at low cost and require deeper returns (≥50 mm) to avoid hotspotting. Their wide beam angles suit large-scale signage and extensive displays.

Find all large sizes in our Large LED Modules collection.

For external shopfronts or lightboxes, try the ROCK4 LED Module: it delivers a 175° beam, dimmability and IP67 protection in a single unit.
