Shenzhen, China – September 2026
Drew, a valued client with a keen eye for performance, specifically requested the high‑grayscale UCS8904B chip for his lighting project. He knew that this chip delivers superior color depth, smoother transitions, and exceptional stability — exactly what his installation required.
Standard cabochon lights typically use UCS2903 or GS8206 chips, but Drew wanted more. So we custom‑designed the PCB to accommodate his preferred chipset, creating a product that exceeds standard performance levels.
ElisaCustom is pleased to announce the release of our custom 45mm Cabochon Pixel Light (Model: XXA-45-360D) , featuring 2‑sided illumination (8 LEDs front, 4 LEDs back), support for RGBW with the UCS8904B chip, and flexible mounting options.
Designed for amusement parks, themed attractions, retail displays, and architectural accent lighting, this cabochon light delivers bright, wide, and captivating light output in a durable 45mm package.

Key Features
1. UCS8904B High‑Grayscale Chip – Drew’s Preferred Choice
This product features the UCS8904B, a 4‑channel constant current LED driver designed for RGBW applications. Drew chose this chip for its superior performance:
UCS8904B Feature | Benefit |
|---|---|
4‑channel output | RGB + pure white (not mixed from RGB) |
65536 grayscale levels | Ultra‑smooth color transitions |
4KHz port scanning frequency | No flicker in video recording |
Single‑wire data transmission | Easy cascading, unlimited points |
≥10m point‑to‑point distance | Flexible installation layout |
±3% inter‑chip current error | Consistent brightness across fixtures |
Built‑in 5V regulator | Direct 12V/24V operation with external resistor |
Output port withstand voltage | Up to 28V |
ESD protection | 8000V (HBM) |
S‑Al anti‑interference technology | Reduces radiation and conduction interference |
Why UCS8904B over standard chips? While conventional cabochon lights use UCS2903 or GS8206, the UCS8904B offers higher grayscale resolution, smoother dimming, and better color accuracy — making it the preferred choice for projects where light quality matters.
2. 2‑Sided Illumination for 360° Visibility
With 8 LEDs on the front and 4 LEDs on the back, this cabochon light provides bright, even illumination from multiple angles — ideal for applications where the light is viewed from different perspectives.
LED Configuration | Effect |
|---|---|
8 front LEDs | Primary illumination, bright and wide |
4 back LEDs | Fill light, enhances visibility from behind |
3. RGBW Support – Pure White + Full Color
Unlike RGB chips that mix colors to create white (which can look tinted), UCS8904B includes a dedicated white channel for pure, clean white light — essential for architectural and accent lighting where white quality matters.
4. Versatile Voltage Options – DC12V or DC24V
Voltage | Best For |
|---|---|
DC12V | Shorter runs, smaller installations |
DC24V | Longer runs, reduced voltage drop |
Power recommendation: For consistent brightness, use a dedicated power supply for every 20–40 units.
5. Durable Mounting – 19mm Hole
The light features a standard 19mm mounting hole (20mm also acceptable), making it compatible with most existing mounting hardware.
6. Flexible Connector Options for Indoor/Outdoor Use
Environment | Connector Type |
|---|---|
Indoor | JST non‑waterproof |
Outdoor | Waterproof (clear or black) |
7. Two Cap Style Options
Cap Style | Appearance |
|---|---|
Spiral | Decorative, textured look |
Straight | Clean, minimalist design |
8. Customizable Cable Length
Cables can be tailored to your specific installation needs — no fixed length constraints.
UCS8904B Technical Deep Dive
Electrical Characteristics
Parameter | Value |
|---|---|
Output current per channel | 18mA (constant current) |
Logic supply voltage | Up to 6.5V (built‑in regulator for higher) |
Output port withstand voltage | 28V |
Operating temperature | -40°C to +85°C |
Storage temperature | -55°C to +150°C |
ESD rating | 8000V |
Voltage Regulation
UCS8904B can be configured for 6V–24V power supplies with external resistors:
Supply Voltage | Recommended Resistor (VDD) |
|---|---|
5V | 100Ω |
12V | 750Ω – 1KΩ |
24V | 2.4KΩ – 3KΩ |
Note: Larger resistor values reduce power consumption but decrease cable distance between ICs. Smaller values increase power consumption but extend cable distance.
Signal Protection
Supply Voltage | Signal Protection Resistor |
|---|---|
12V | 68Ω (input and output) |
24V | 120Ω (input and output) |
Add a 104pF high‑frequency capacitor between power and ground to reduce switching interference.
