Advantages of UV LED
> No IR radiation, less heat > More compact than mercury systems
> Low voltage > No shutters or glass quartz
> Consistent and immediate UV output over operating life
> No UVC and therefore no ozone emitted, eliminating need for exhaust
> Does not contain heavy metals (mercury)
> Longer life, + 20,000 hrs as compared to 1,500 hrs on a standard UV mercury lamp
> Easier to convert materials that are heat sensitive
> LEDs are more efficient than mercury bulbs
Advantages of UV LED
> More expensive technology
> Limited spectral output
> Higher ink cost because of special photoinitiator and formulation
