• DIY task lighting, backlighting, signage, and instrument panels.
• Prototyping and lab setups with LED driver modules and heat-sinking.
• Emitter replacements or upgrades in compatible 3W fixtures.

⚠️ Electrical & Thermal Design Notes

• Drive mode: Use a constant-current driver set between 590–700 mA. Do not connect directly to a voltage source.
• Voltage headroom: Ensure your driver accommodates the LED’s forward voltage of 3.4–3.8 V plus driver overhead.
• Thermal management: Mount to a suitable heat sink or metal-core PCB with thermal interface material to maintain reliability and lifespan.
• Control interfaces: When using Arduino/Raspberry Pi, switch the LED via a driver IC or MOSFET-based constant-current stage; do not drive directly from GPIO.
• Polarity & protection: Observe anode/cathode orientation and avoid reverse voltage. Handle with ESD precautions.
