🔗 Integration & Compatibility

For reliable operation with Arduino, Raspberry Pi, and other microcontroller platforms, drive this LED using a constant-current LED driver set to 300–350 mA. Do not connect directly to 3.3 V or 5 V GPIO pins. Ensure adequate thermal management (heat sink/metal core PCB) to maintain performance and lifetime. Typical forward voltage ranges from 3.0–3.8 V at the rated current.

🛠️ Typical Applications

• Fluorescence excitation and materials inspection
• UV curing and resin hardening (small-scale)
• Currency/security marking and leak detection
• DIY instruments, sensors, and electronics modules

⚠️ Notes & Safety

• UV Safety: Avoid direct eye and prolonged skin exposure; use appropriate UV protective eyewear.
• Thermal Management: Mount on a heat-dissipating surface; monitor junction temperature to ensure longevity.
• ESD Precautions: Handle using anti-static procedures.
• Driver Recommendation: Use a constant-current driver; series resistors alone are not recommended for high-power LEDs.
