1W RGBW
The Φ30 Circular 12V RGBW LED Module is a high-density, integrated light engine engineered for custom spotlight, accent, and architectural RGBW luminaires. Built on a 1.6mm thick aluminum metal-core PCB (MCPCB) with heavy 2oz copper foil and 2.0 W/m.K thermal conductivity, this board mounts a high-power Cree XML2 5050 4-in-1 RGBW LED emitter (Red, Green, Blue, Neutral White).
Designed with an integrated SMD resistor network directly on the circuit board, it allows direct DC 12V input without requiring external constant-current drivers. Featuring a common-positive (+DC12V) and independent channel control (R-, G-, B-, W-) 5-pad layout, it seamlessly integrates with standard 12V PWM RGBW controllers.

Key Technical Advantages
Integrated 12V Direct Plug-and-Play Design: Built-in surface-mount resistors (WR1, GR1, BR1, RR1 series network) convert standard 12V DC voltage down to optimal chip operating levels, allowing direct hookup to 12V power supplies or PWM dimming controllers without extra driver boards.
High-Power Cree XML2 5050 RGBW Emitter: Incorporates a genuine Cree XML2 5050 4-in-1 diode combining Red, Green, Blue, and White dice under a single lens for rich color mixing and crisp, dedicated white light output.
Compact Φ30 Form Factor: The ultra-small 30mm round aluminum footprint allows seamless integration into tight fixture housings, puck lights, motorcycle/automotive accents, and stage light optics.
Heavy 2oz Copper & 2.0 W/m·K Aluminum Core: Utilizes a 1.6mm thick aluminum substrate with heavy 2oz copper traces and 2.0 W/m·K thermal conductivity, rapidly draining heat away from the Cree die to prevent lumen decay.
Standard Common-Positive PWM Control: Clearly silk-screened solder pads (+DC12V, R-, G-, B-, W-) ensure foolproof solder connection with standard low-side switching RGBW controllers and smart home PWM dimmers.
Applications & Fixture Compatibility
Architectural & Landscape Accents: Mini RGBW outdoor spotlights, wall washers, fountain lights, and garden accent fixtures.
Entertainment & Stage Lighting: Compact RGBW moving heads, PAR light inserts, and custom DMX-controlled color-mixing fixtures.
Automotive & Marine Custom Lighting: 12V vehicle interior accent lights, motorcycle auxiliary lights, and boat deck puck lights.
Custom OEM/ODM DIY Luminaire Design: Ideal drop-in RGBW light source for 3D printed lamps, smart home fixtures, and desktop ambient lights.
Frequently Asked Questions (FAQ)
Q1: Do I need a constant current driver for this 30mm RGBW LED module?
A: No. This module features an integrated onboard resistor circuit designed specifically for 12V DC direct power input. You can connect it directly to a 12V DC power supply or a standard 12V PWM RGBW controller.
Q2: How are the solder pads configured on this board?
A: The board uses a 5-pad common positive layout marked on the silkscreen:
+DC12V: Positive 12V Power Input
R-: Negative control pad for Red channel
G-: Negative control pad for Green channel
B-: Negative control pad for Blue channel
W-: Negative control pad for White channel
Q3: Is an external heat sink required for this 30mm aluminum module?
A: Yes. Although the 1.6mm 2.0W/m.k aluminum base efficiently spreads heat across the 30mm board, mounting it to an external aluminum heat sink or fixture housing using thermal grease is strongly recommended during continuous full-power operation to maintain LED longevity.
