3W Power LED Yellow 💛

High-efficiency, single-emitter 3 W yellow power LED built on a copper bracket for robust thermal performance. Powered by an Epileds (Taiwan) chip, this round “light bead” offers a wide 120° beam angle and up to 200 lm luminous flux—ideal for custom lighting, indicators, and embedded designs. Perfect for Arduino and Raspberry Pi projects when driven by a constant-current LED driver module.{IMG_TAG_0}

Integration Tips for Engineers and Hobbyists 🛠️

• Use a constant-current LED driver set to 600–700 mA; do not power directly from a battery, bench supply, or GPIO.
• Ensure adequate thermal management (heat sink or metal-core PCB) to maintain reliability and luminous output.
• Observe polarity and the specified forward voltage range (3.2–3.4 V) at the rated current.
• When integrating with Arduino or Raspberry Pi, use appropriate driver circuitry (buck/linear LED drivers) rather than series resistors alone for best performance.
• Follow ESD-safe handling and proper soldering practices to protect the LED die.
