5V 3W golden yellow LED module with onboard resistor, 2000K, plum aluminum substrate, direct drive, for vintage atmosphere decor & DIY lighting projects

This is a pre‑assembled 3W high‑power golden yellow LED light source mounted on a 20 mm plum‑star aluminum PCB, integrated with onboard SMD current‑limiting resistor. It works directly with DC 5V power supply without external constant‑current driver, simplifying circuit design and cutting BOM cost. It outputs warm golden‑yellow light at 2000K color temperature with a 120° wide beam angle. High‑conductivity aluminum substrate delivers excellent heat dissipation during continuous operation, reducing light decay and keeping stable brightness. Ideal for vintage‑style lamps, decorative ambient lighting, DIY projects and low‑voltage golden‑yellow lighting equipment.

• 5V Direct‑Drive With On‑Board Resistor: Built‑in current‑limiting resistor, directly powered by USB power banks or 5V adapters. No extra driver needed, simplify circuit layout and lower component costs.
• Optimized Plum Aluminum Heat‑Dissipation PCB: Special star‑plum structure maximizes heat transfer area. Outstanding thermal performance suppresses overheating and light decay for long‑hour stable operation.
• Premium Golden‑Yellow LED Chip: Copper‑bracket and gold‑wire bonding delivers soft, pure 2000K golden‑yellow light output, low thermal resistance and reliable performance.
• Clear Polarity Silkscreen: Obvious plus/minus marking prevents reverse‑connection damage for fast and error‑free soldering & assembly.
• Wide‑Angle Flood Lighting: 120° beam angle realizes large‑area golden‑yellow illumination without extra secondary optics for most DIY and lamp projects.
• Full‑range Color Selection: Available in golden yellow, cool white, red, warm white, green, blue and more colors for diversified application scenarios.
• Ready‑to‑use Integrated Module: Fully pre‑mounted unit, no secondary PCB processing required for rapid prototyping and mass‑volume production.
