COLOUR LIGHTBOX MODULE COLLECTION
RGB and RGBW LED lightbox modules
Compare three 24V colour LED bars for illuminated graphics and sign projects. Choose RGB for red, green and blue colour mixing, or RGBW when the design also calls for a dedicated white channel. The available installation space, light direction and control arrangement are as important as the colour choice.
This collection brings together the actual RGB and RGBW references in our lightbox module range. Use the comparison to select a sample, then approve the complete lighting and control package with the intended display construction.

All three models list 24V DC input. The power values below apply to individual bars. Keep the complete ordering reference when requesting a matching cable or repeat order, because the channel count, body dimensions and connections differ.
| Model | Colour channels | Overall size | Power | LEDs | Lens reference | Connection reference |
|---|
| SL-BL021-RGB240 | RGB | 480 × 27 × 16mm | 24W | 6 | 20 × 60° | Four coloured leads with black plugs |
| SL-BL034-RGB320 | RGBW | 480 × 32 × 22mm | 32W | 6 | Confirm ordered optics | 5-pin male/female plugs |
| SL-BL043-RGBW300 | RGBW | 400 × 30 × 22mm | 30W | 5 | 25° | Confirm ordered lead/connector |
Choose RGB or a dedicated white channel
The RGB reference is intended for colour mixing from three colour channels. If the graphic must also be shown using a dedicated white source, compare the two RGBW references. Assess the coloured and white appearances with your actual print and diffuser, since the same colour setting can look different through different materials.
Model SL-BL034-RGB320 lists a white-channel ordering range of 6000–8000K and a CRI90+ white-channel option available to order. State those requirements when requesting a sample; they are not a guarantee that every version or colour state has the same output or colour rendering. Confirm the white-channel specification of SL-BL043-RGBW300 separately.
Match the controller to the selected bar
RGB and RGBW need different channel arrangements. Confirm the output channel count, wiring order, connector pin assignment and permitted load with the proposed controller. A plug that appears similar is not enough to establish electrical compatibility.
The collection identifies the light bars. Ask for the controller, power supply and interconnection cables as a specified package when you need a complete system. Describe whether the project requires a fixed colour, switching between white and colour modes, or a particular control interface so that the suitable configuration can be confirmed.
Allow for the optics and mounting space
The 400mm and 480mm lengths give different physical options. Check the complete width and height as well as the length, leaving room for the connectors and cable route. The 25° lens on SL-BL043-RGBW300 differs from the 20 × 60° optics listed for the RGB bar, so evaluate their light direction in the intended enclosure.
Confirm the fixing arrangement against the drawing. SL-BL034-RGB320 lists 5mm fixing holes at the bar ends. Provide the internal frame dimensions, display depth and mounting photographs if the bar will join an existing lightbox system.
Approve the sample behind the actual graphic before setting the final bar quantity and spacing. State any outdoor or damp-use requirement in the enquiry so the complete installation and protection requirements can be reviewed.
