This demonstration shows block LED modules working as individually controlled pixels for counters, ceilings, signage and architectural features.
Modules need the right
control and power.
A complete installation includes compatible control, a correctly sized 24V constant-voltage power supply, signal wiring and power distribution.
Choose the LED module
Select single color, tunable white, RGBW or RGBCCT, then choose static, SPI or DMX control.
Match the controller
Multi-channel, SPI and DMX modules require a controller compatible with their channel type and protocol.
Size the 24V power supply
Calculate total module wattage and add at least 20% capacity for reliable long-term operation.
Built for more than
channel letters.
From uniform white backlighting to dynamic pixels, choose the module and protocol around the visual effect and installation scale.
Signs & logos

Questions from sign
makers and lighting
designers.
LED modules are compact lighting units consisting of LEDs mounted on a PCB with integrated electrical connections. Compared with traditional LED strips, LED modules are typically designed for applications requiring higher brightness, wider beam angles, flexible installation, or customized layouts. They are widely used in architectural lighting, illuminated signage, commercial displays, decorative lighting, and OEM lighting products.
LED strip lights are continuous flexible lighting solutions designed for linear illumination, while LED modules are individual lighting units that can be arranged freely according to the application. LED modules generally provide higher brightness, flexible spacing, and greater installation versatility, making them suitable for illuminated signs, display lighting, architectural lighting, and custom lighting systems.
SPI LED modules allow individually addressable pixel control, making them ideal for dynamic lighting effects, animations, and digital displays. DMX LED modules provide synchronized control across multiple fixtures and are widely used in architectural lighting, façade lighting, entertainment venues, and large-scale commercial projects. The right choice depends on your lighting effects, installation scale, and control requirements.
RGBW LED modules combine red, green, blue, and white LEDs to deliver vibrant colors with dedicated white illumination. RGBCCT LED modules integrate red, green, blue, cool white, and warm white LEDs in a single package, allowing both dynamic color effects and adjustable white color temperatures. RGBCCT modules are ideal for applications requiring flexible ambiance and tunable white lighting.
The power supply should match the input voltage and total power consumption of your LED modules. Most LED modules operate with 12V or 24V constant voltage power supplies. For long-term reliability, it is recommended to choose high-quality power supplies with sufficient power margin and the appropriate IP rating for the installation environment.
Controller selection depends on the LED module type. Single Color modules typically use dimmers or PWM controllers, Tunable White modules require CCT controllers, RGBW modules use RGBW controllers, while SPI and DMX LED modules require compatible SPI or DMX512 controllers. Choosing the correct controller ensures reliable communication and optimal lighting performance.
Yes. We provide customized LED module solutions for OEM and ODM projects, including PCB dimensions, LED types, color temperatures, CRI options, voltages, control protocols, beam angles, waterproof ratings, wiring, connectors, and private labeling. Our engineering team works closely with customers to develop solutions tailored to specific project requirements.
Our LED modules can be supplied with certifications according to different market requirements, including CE, RoHS, UKCA, UL, and other applicable standards depending on the product configuration and destination market. Please contact us for certification details related to your specific project.
The MOQ depends on the product type and customization requirements. Standard LED modules generally have lower minimum order quantities, while customized PCB designs, special LED configurations, or private-label products may require different MOQs. Please contact our sales team for detailed quotation and MOQ information.
Production lead time varies depending on product specifications and order quantity. Standard LED modules are typically produced faster, while customized products may require additional engineering evaluation and sample confirmation before mass production. Our team will provide an estimated production schedule based on your project requirements.
The right LED module depends on your application, required lighting effect, control method, installation environment, and project budget. Single Color modules are suitable for general illumination, Tunable White modules provide adjustable white lighting, RGBW modules deliver vivid colors with dedicated white light, while SPI and DMX modules are designed for programmable and synchronized lighting systems. If you’re unsure which solution best fits your project, our team can help you select the most suitable LED module, power supply, and controller combination.
