UV-LED systems are clearly on a rise and enabling machine designs and installations that couldn’t be realised in former times with conventional UV. But is the technology one to one replaceable or is there still a need for Arc systems or even combinations of both Arc and LED? We will dive deep into this question and have a look at the differences of Arc and LED as well as the possibilities available with UV-LED. A short outlook to future power levels and current efficiencies will give you a good overview of where the technology is heading towards.
