LED Modules

Looking for professional-quality LED modules for signage? You've come to the right place. At GP Trader, we've been working with sign shops, installers, and outdoor advertising companies across Spain and Europe for years. We know what you need: reliability, great prices, and a supplier that won't let you down.

Types of LED Modules: 12V and 24V for Every Project

We work with 12V LED modules and 24V LED modules to adapt to every type of installation. 12V modules are ideal for small and medium projects, while 24V modules allow longer runs with less voltage drop, perfect for large signage installations.

Our LED modules offer high luminous efficiency, up to 170 lm/W in the most advanced models. This means lower power consumption and better long-term performance.

LED Modules for Signage: Channel Letters and Light Boxes

Professional LED modules for signage are our specialty. Each project has its particularities: for small channel letters, you need compact 1 LED or 2 LED modules that adapt to curves and corners. For large light boxes, go with 3 or 4 LED modules in series that provide uniform illumination.

We work with all types of applications: illuminated signs, channel letters in PVC, aluminum or stainless steel, interior signage for shopping centers, storefront lighting, advertising displays, totems and much more.

IP67 Injection LED Modules: Total Outdoor Resistance

For outdoor installations, IP67 injection LED modules are not optional—they're mandatory. Our IP67-rated modules are completely sealed against water and dust through an injection process that guarantees total protection, while IP68 modules withstand temporary immersion.

The injection encapsulation protects LED components and connections from moisture, dust, and temperature variations, ensuring a lifespan of over 50,000 hours even in adverse conditions.

LED Modules in Colors and White Temperatures (3000K to 6000K)

We have the full color range: from RGB LED modules for dynamic effects to fixed colors like Red, Green, and Blue. Plus, you can choose the perfect atmosphere with our white color temperatures: 3000K (warm), 4500K (neutral), or 6000K (cool). All our products feature IP67 or IP68 protection, ensuring durability in outdoor installations.

Custom LED Module and PCB Manufacturing

We understand that some projects require unique technical specifications that are not covered by standard solutions. That is why we offer a specialised design and manufacturing service for custom LED modules. We can develop bespoke PCBs, adjust the exact luminous output required for your application, and supply custom wiring (specific lengths and connectors) to simplify chain assembly. If you have a complex design or a particular technical need, we manufacture the LED solution that best fits your structure.

Samsung LED Modules for Signs: Guaranteed Quality

We work exclusively with Samsung LED and Osram chips that guarantee stable color temperature (6000K-6500K), high efficiency up to 170 lm/W, and a lifespan exceeding 50,000 hours. Samsung LED modules for signs are the choice of professionals who don't want to return to a job due to lighting failures.

FAQ - Frequently Asked Questions about LED Modules

How many LED modules do I need to illuminate a channel letter?
It depends on the letter size. As a general rule, for letters up to 30cm in height, place one module every 8-10cm. For larger letters, increase density in curved areas to avoid dark spots. What's the difference between 12V and 24V LED modules?
Both work at low voltage, but 24V modules can run longer series with less voltage drop. For small installations (under 5m), 12V is sufficient. For larger projects, we always recommend 24V. How long do LED modules last?
A quality Samsung or Osram LED module has a lifespan exceeding 50,000 hours. That's more than 5 years of continuous operation. Of course, this depends on proper installation and adequate cooling.

LED Modules for Light Boxes: Uniform Professional Illumination

Light boxes are among the most widely used advertising displays in retail stores, shopping centres, airports, and transport stations. Achieving uniform illumination without hot spots or shadows depends entirely on the LED module selection. At GP Trader, we supply modules specifically engineered for light box backlighting, both frontlit and backlit configurations.

The critical technical factor is the distance between the module and the diffuser panel: for light boxes with a depth of 8 to 12 cm, we recommend 3-LED modules with 160°-175° optics that spread light evenly from a short distance. For deeper boxes (15-20 cm), 4-LED modules deliver higher luminous output and cover larger areas per unit.

Our LED modules for light boxes feature Samsung chips with efficiency up to 170 lm/W, reducing energy consumption by up to 60% compared to traditional fluorescent tube lighting. IP67 protection ensures reliable performance in outdoor light boxes exposed to rain and temperature fluctuations.

For large-format projects (monoliths, advertising totems, bus shelter displays), our 24V solutions allow runs up to 20 metres without noticeable voltage drop, simplifying installation and reducing wiring requirements.

LED Modules for Shop Windows and Retail Displays

Shop window lighting is a fundamental visual marketing tool for retail. A well-illuminated storefront captures pedestrian attention, highlights displayed products, and communicates brand identity. LED modules for shop windows enable flexible lighting compositions that adapt to any display format.

For fashion boutiques, jewellers, and opticians, we recommend modules with a 4500K (neutral white) colour temperature, which provides faithful colour rendering without altering product tones. For food retail (bakeries, butchers, greengrocers), 3000K (warm white) enhances natural tones and conveys a sense of freshness and quality.

Wide-angle LED modules (170°-175°) are the ideal solution for shallow shop windows, distributing light uniformly even at close distances from the glass. For decorative effects and seasonal displays, RGB modules allow colour changes to match campaigns or seasonal themes.

GP Trader supplies retail chains, interior designers, and visual merchandising companies across Europe, with real stock and 24-48h shipping to Spain, 48-72h to Portugal and France.

LED Modules for Illuminated Signs: Professional Selection Guide

Choosing the right LED modules for signs depends on three technical factors: sign type (channel letters, light box, projecting sign), available depth, and total surface area to illuminate. An incorrect selection results in hot spots, dark zones, or excessive energy consumption.

For small and medium channel letters (up to 30 cm height), 1-LED and 2-LED modules are the best choice due to their compact size and ability to follow curves. For large-format letters (50 cm or more), 3-LED modules provide the necessary output.

For projecting signs and double-sided panels, illumination must cover both faces. Our projecting sign modules feature side-emitting optics that project light towards the edges, eliminating the bright-centre/dark-edges effect.
