UVA ( Curing )

UV Lamp UV LED
Pros High Power Density
Broad Spectrum  Surface Curing
Lower Heat Generation
Energy Saving
Quick On/Off
HQ Printing, Energy Saving
Longer Lifetime (~20kh)
Cons High Heat Generation
Broad Spectrum  Ozone Generation
Warm-up Time (~30min)
Short Lifetime (~2kh)
Weak Surface Curing

UVC (Sterilization)

UV Lamp UV LED
Pros High Energy Efficiency (10~30%)
High Power Density (Mid Pressure)
Low Voltage, Small in Size and Weight
High Mechanical Strength
Eco-Friendly (No Mercury)
High Potential in Technical Progress
Cons Sensitive to Environment Temperature (Low Pressure)
High Surface Temperature (Mid Pressure)
Fragile  Mercury Contamination
High Voltage Driver, Bulky
Lower Energy Efficiency (2~3%)
( Expected to reach ~15% in 5 years )
