When sourcing High Power LEDs, you must prioritize Luminous Efficacy (lm/W) and Thermal Management. Look for LEDs with a high lumen output (e.g., CREE, Osram, or Luminus chips) that maintain efficiency at high currents. Ensure the Color Temperature (CCT) aligns with the use case—5000K-6500K (Cool White) is standard for searchlights, while 3000K-4000K (Warm/Neutral White) offers better color rendering in foggy conditions. Additionally, verify the Forward Voltage (Vf) and Maximum Drive Current to ensure compatibility with your torch's driver circuit.
