🔧 Electrical & Thermal Design Notes

• Use a constant-current LED driver set to 900 mA. Do not drive directly from a fixed-voltage supply.
• Allow headroom in your supply voltage for the driver (e.g., 12–24 V supply with a suitable driver module).
• For Arduino or Raspberry Pi control, use PWM via the driver’s DIM/EN pin or a MOSFET-based LED driver module; never connect the LED to GPIO pins directly.
• Mount the LED to a proper heat sink or metal-core PCB with thermal interface material. Inadequate cooling will shorten lifespan or damage the emitter.
• Observe correct polarity and current limiting; check forward voltage at operating temperature.

🧪 Typical Applications

• UV fluorescence and “blacklight” effects
• Resin and adhesive curing (UVA-sensitive materials)
• Inspection and quality control (e.g., PCB/conformal coating checks)
• Counterfeit detection and security marking
• Leak detection with fluorescent dyes

⚠️ Safety Notes

• UVA radiation can be harmful with prolonged exposure. Avoid direct eye/skin exposure.
• Wear UV-blocking eyewear and use appropriate shielding/enclosures.
• Ensure adequate ventilation and thermal management during operation.
