🛠️ Integration Tips (Arduino / Raspberry Pi / Microcontroller)

• Drive with a constant‑current LED driver set to 590–700 mA; do not connect directly to a voltage source.
• Expect a forward voltage of 3.4–3.8 V; allow headroom in your driver’s compliance voltage.
• Use PWM dimming via a MOSFET or LED driver IC controlled by a microcontroller (Arduino, Raspberry Pi).
• Provide adequate heatsinking to the copper bracket or star base to manage thermal load at 3W.
• Observe ESD precautions and correct polarity during assembly.

⚠️ Safety Notice

This LED emits UVA (near‑UV) radiation. Avoid direct exposure to eyes and skin. Use appropriate UV eye protection and follow standard lab safety practices.
