Engineered for large-format tension fabric lightboxes, high-impact exhibition booth walls, and commercial architectural displays. This 32W RGBW bar integrates a dedicated pure white LED chip (6000K–8000K) alongside high-output RGB diodes — delivering true daylight-white backlighting and full dynamic color-changing from a single bar. Ideal for installations where standard 24W RGB output is insufficient.
Why Upgrade to RGBW 32W?
Standard RGB bars mix red, green, and blue to approximate white — resulting in a muddy, color-shifted tone. This RGBW bar eliminates that compromise entirely.
- 4-in-1 RGBW Chip — True Pure White: A dedicated white LED channel (6000K–8000K) produces crisp, neutral daylight white with no color cast — essential for fabric graphics that require accurate white backgrounds.
- 32W High-Lumen Output (1300–1500 lm): Over 30% more output than standard 24W RGB bars. Engineered for large-format frames where center-fill brightness is critical.
- 10°×50° Asymmetric Optical Lens: Narrower horizontal angle concentrates light deep across the fabric surface, eliminating edge shadows and hotspots on wide or tall displays.
- Switch Constant-Current Driver (320mA/circuit): Built-in constant-current circuitry protects LEDs against voltage fluctuation — ensuring uniform brightness across every bar in a series run.
- Heavy-Duty Aluminum PCB (480×32×22mm): Larger substrate provides superior thermal management and long-term lumen stability.

Why one power supply and one controller per 2 bars?
Each bar draws 32W at DC24V. The maximum series connection is 2 bars per run (64W total). Running more than 2 bars in series causes voltage drop, uneven brightness, and potential damage. Each 80–100W power supply handles one run of 2 bars with safe headroom. Each RF RGBW controller manages one independent run.
Why Professionals Choose This Bar
True Pure White — No Color Compromise
The dedicated white LED channel delivers crisp 6000K–8000K daylight white independently of the RGB channels. Switch between full-color dynamic effects and clean white backlighting without any color mixing artifacts — critical for brand-accurate fabric graphics.
High-Lumen Output for Large Backlit Displays
At 1,300–1,500 lm per bar, this is the solution for backlit fabric frames exceeding 2m in any dimension. Where standard 24W RGB bars leave center areas dim, the 32W RGBW bar pushes light uniformly across the full display surface.
Precision 10°×50° Lens for Deep Projection
The narrower 10° horizontal beam concentrates light further into the display than standard 20°×60° lenses — eliminating edge shadows on tall or wide frames and ensuring consistent illumination from corner to corner.
Constant-Current Protection
Built-in switch constant-current circuitry maintains stable 320mA output regardless of input voltage variation — protecting LEDs and ensuring color consistency across every bar in a daisy-chain run.
Aluminum PCB — Long Lifespan
The larger 480×32×22mm aluminum substrate provides superior thermal management — maintaining consistent color output and lumen stability across 50,000+ hours of operation.

Wiring & Power Guide
Important: Maximum 2 bars per series run (64W). Exceeding this limit causes significant voltage drop and may damage the bars. Use multiple independent runs with separate power supplies for larger installations.
| Pack Size | Runs Required | Power Supplies Needed | Controllers Needed |
|---|---|---|---|
| 10-Pack | 5 | 5× 80–100W PSU | 5× RF RGBW Controller |
| 50-Pack | 25 | 25× 80–100W PSU | 25× RF RGBW Controller |
| 100-Pack | 50 | 50× 80–100W PSU | 50× RF RGBW Controller |
Each 80–100W power supply supports one run of 2 bars (64W actual load). Each RF RGBW controller manages one independent run.

Frequently Asked Questions
What is the main difference between RGB and RGBW edge-lit light bars?
Standard RGB bars mix Red, Green, and Blue to create white light — which often has a bluish or pinkish tint. RGBW bars feature a dedicated White LED chip (6000K–8000K), producing true pure daylight white while maintaining full RGB color capabilities. For brand-critical fabric graphics where white accuracy matters, RGBW is the professional choice.
Why is the maximum series connection only 2 bars?
Each 32W bar draws significantly more current than a standard 24W RGB bar. Beyond 2 bars in series, voltage drop becomes critical — causing uneven brightness, color inconsistency, and risk of damage. Always use a separate 80–100W power supply for each group of 2 bars.
Why is 32W high-power output important for large backlit fabric displays?
Larger displays (over 2 meters in height or width) require higher lumen intensity to push light uniformly through the center of the fabric. With 32W and 1,300–1,500 lm per bar, this bar ensures vibrant, shadow-free edge lighting across extensive fabric graphics where standard 24W bars fall short.
Can I mix RGBW bars with my existing RGB installation?
Not recommended. RGBW bars use a 5-pin SM JST connector and require a dedicated RGBW controller, while RGB bars use a 4-pin connector and RGB controller. The connectors are physically different — they cannot be plugged into each other. Use RGBW bars as a complete system for consistent results.
How are these light bars installed on aluminum lightbox frames?
The bar measures 480×32×22mm and mounts via dual 5mm screw holes on each end. Male and female 5-pin SM JST connectors enable rapid daisy-chain series installation along the frame perimeter — no soldering required.
