LED lighting is far more energy-efficient than incandescent or fluorescent sources, reducing electricity use significantly when deployed at scale.

Large LED modules offer high output, wide beam angles and deep returns—ideal for signage, lightboxes and large-scale displays. This guide covers their advantages, applications and available products.

What makes large LED modules different?

Large LED modules feature deeper return depths (≥50 mm, up to 200 mm double-sided) to prevent spotting and deliver a smooth flood of light. They achieve 130–150 lm/W (some up to 225 lm/W), far surpassing the ~25 lm/W of small modules, and their higher beam angles provide wide coverage at lower cost.

What are large LED modules used for?

Designed for large-scale installations, they power flex-face signage, projecting signs, lightboxes, LED panels and edge-lit displays. Their efficiency and output make them perfect for exterior shop fronts, event backdrops and any application requiring uniform, high-output illumination.

Frequently asked questions

What are typical watts and lumens?

Standard and large modules typically deliver 100–150 lm per watt, with some high-output models varying as needed.

Why is beam angle important?

A wider beam angle spreads light more evenly, improving coverage without hotspots.

Are LEDs really efficient?

Yes. Traditional bulbs achieve only ~16 lm/W, whereas large LED modules deliver 95–150 lm/W.

What do IP65 and IP67 mean?

IP65: dust-tight and water-jet resistant. IP67: dust-tight and safe for brief immersion in water.
