Key Features

1. 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.

2. RGBW Support with UCS8904B Chip

The UCS8904B is a 4-channel constant current LED driver designed for RGBW applications. Key technical features include:

Why choose RGBW? 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.

3. Versatile Voltage Options – DC12V or DC24V

Power recommendation: For consistent brightness, use a dedicated power supply for every 20–40 units.

4. Durable Mounting – 19mm Hole

The light features a standard 19mm mounting hole (20mm also acceptable), making it compatible with most existing mounting hardware.

5. Flexible Connector Options for Indoor/Outdoor Use

6. Two Cap Style Options

7. 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:

Note: Larger resistor values reduce power consumption but decrease cable distance between ICs. Smaller values increase power consumption but extend cable distance.

Signal Protection

Add a 104pF high-frequency capacitor between power and ground to reduce switching interference.

Applications
