230nm LED vs. 222nm Excimer Lamp: Which Far-UVC Source is Better for Mass Production?

The Far-UVC Rivalry

For years, 222nm excimer lamps were the only game in town for safe UV disinfection. However, as semiconductor technology matures, the 230nm UVC LED has emerged as a disruptive alternative.

Key Comparison Metrics:

1. Form Factor: Excimer lamps are bulky, gas-filled glass tubes. Our 230nm LEDs use a compact 3.6*3.6 mm SMD package, allowing for integration into slimline HVAC systems and portable handheld devices.

2. Operational Stability: Excimer lamps require high-voltage inverters, which increase EMI interference and system complexity. 230nm LEDs run on standard DC current, simplifying PCB design.

3. Instant On/Off: LEDs reach peak power in milliseconds and handle frequent switching cycles perfectly—ideal for sensor-activated disinfection. Excimer lamps suffer from shortened lifespans if switched too frequently.

Strategic Advantage for OEMs

For manufacturers in the medical and industrial sectors, the 230nm LED offers a lower Total Cost of Ownership (TCO) and a more stable supply chain compared to niche excimer gas lamps.
