Built with Epistar chips, gold wire, and a copper lead frame, it ensures excellent heat dissipation, high brightness, and a lifespan exceeding 50,000 hours. Each channel operates at a typical 20mA with a 120° wide viewing angle for uniform illumination. Ideal for 8mm/10mm FPC strips, rigid bars, pixel modules, and decorative lighting, this 0.3W RGBW LED supports standard PWM dimming and is compatible with popular addressable ICs like SK6812 and WS2815. Whether you need dynamic color effects or reliable warm/cool white output, the Yulong 4040 RGBW offers professional-grade performance in a space-saving footprint.
4-in-1 Space-Saving Design: Integrates R/G/B/W four chips in a compact 4.0×4.0×1.55mm SMD package, perfect for high-density 96/120 LEDs/m narrow strips.
Premium Chip & Materials: Epistar dice, gold wire bonding, and copper bracket ensure high luminous efficacy, excellent heat dissipation, and long lifespan.
True White + Full Color: Dedicated white channel (1500K–25000K) delivers pure white light alongside rich RGB mixing for versatile lighting scenes.
Low Power & Easy Drive: 20mA per channel (0.3W total), compatible with constant-voltage systems and addressable ICs (SK6812-RGBW, WS2815, etc.).
Wide 120° Beam Angle: Provides uniform, wide-range illumination for linear lighting, cove lights, signage, and architectural decoration.
