Detailed comparison of UVLED lamps vs traditional mercury lamps, helping you choose the right UV light source based on your application needs
| Feature | UVLED Lamp | Mercury Lamp (Medium/High Pressure) |
|---|---|---|
| Working Principle | LED chips emit UV directly | UV generated by ionizing mercury vapor |
| Spectrum Characteristics | Narrow band, single wavelength | Broad band, includes UV, visible, IR |
| Startup Time | Instant on, no warm-up needed | Requires 3-5 minutes warm-up |
| Lifespan | 10,000-50,000 hours | 500-3,000 hours |
| Energy Consumption | Low, energy efficient | High, generates significant heat |
| Heat Generation | Low, suitable for heat-sensitive materials | High, requires cooling system |
| Environmental Impact | Mercury-free, eco-friendly | Contains mercury, requires special disposal |
| Initial Cost | Higher | Lower |
| Maintenance Cost | Low, long lifespan | High, frequent replacement needed |
| Cost Type | UVLED Lamp | Mercury Lamp | Notes |
|---|---|---|---|
| Equipment Purchase Cost | High | Low | UVLED initial investment is 2-3x mercury lamp |
| Energy Cost | Low | High | UVLED consumes 30-50% less energy |
| Maintenance & Replacement | Low | High | Mercury lamps need frequent tube replacement |
| Cooling Cost | Low | High | Mercury lamps require powerful cooling systems |
| Long-term Total Cost | Low | High | UVLED recovers extra investment in 2-3 years |
