When should you choose a 4-LED module instead of a 3-LED model?

The four-LED 24V RGB model suits large signs and long runs; the three-LED 12V model suits shallow channel letters and small installations.

For signs over 15–20 linear metres or greater colour intensity per module, choose the 24V four-LED model. For small letters or existing 12V wiring, the three-LED model is more economical and efficient.

Frequently asked questions

How many RGB LED modules do I need per square metre?
For uniform lighting in 100 mm-deep light boxes, we recommend 25–35 RGB 1.44 W LED modules per square metre. For RGB channel letters, allow approximately one module every 8–10 cm of linear stroke.
Is this RGB LED module compatible with DMX, Bluetooth or Wi-Fi controllers?
Yes. This is a common-anode analogue RGB module compatible with standard 12/24 V RGB controllers, including IR remotes, DMX512 decoders, Bluetooth receivers, Wi-Fi controllers and professional DMX consoles.
What is the recommended maximum run length at 24 V?
You can connect up to 20–25 modules per 24 V branch without noticeable voltage drop. For longer runs, feed the circuit from both ends or divide it into parallel branches from the power supply.
Is it suitable for outdoor use?
Yes. The IP67 encapsulation protects the module against rain, dust and moisture. We still recommend sealing cable joints with heat-shrink tubing or neutral-cure silicone.
What is the difference between this RGB module and a digital RGB (SPI) module?
This is an analogue RGB module, so every module in the installation changes colour together. Digital RGB modules using WS2811 or SPI control can address each pixel independently for sequences and animations, but require a compatible digital controller.
What warranty does this RGB LED module include?
The module includes a three-year warranty against manufacturing defects, provided the specified 24 V DC supply and installation conditions are observed.

24V RGB LED module for channel letters and dynamic illuminated signs

The GPT-50504RGB combines four SMD5050 RGB LEDs in a compact 37 × 42 × 8.1 mm housing. Its 160° beam angle provides broad, even coverage inside channel letters, shallow signs and light boxes while its 24V DC supply helps reduce voltage drop across longer installations.

Each module consumes 1.44W and delivers 20–22 lumens per LED. The aluminium PCB, over 2 mm thick, improves heat dissipation and supports a rated lifespan of up to 50,000 hours. Epistar LEDs are fitted as standard; a Samsung LED option is available to order.

Analogue RGB control and professional installation

This is an analogue RGB module: all modules connected to the same controller change colour together. It works with compatible 12/24V RGB controllers, DMX512 decoders, Bluetooth or Wi-Fi receivers and professional RGB control systems. It does not provide individual pixel control.

The IP67 encapsulation protects the electronics against dust, rain and moisture. The rear 3M PE Foam tape facilitates initial positioning on a clean surface; cable joints should still be sealed correctly for outdoor installations.

Applications

Supplied in antistatic bags of 100 modules and covered by a three-year warranty against manufacturing defects, subject to correct 24V DC installation.
