MERCURY UV
Silicon Diode LED
Low normally quantified in hundreds of watts/hr
More than 20000 working hrs
60 C max, measured in lamp emitting window
Pure UV
No mercury and other dangerous substances
Glass window cleaning only
GLED UVs
Fragile cylindrical quartz bulbs
High, normally quantifies thousand of watts/hr
Varying from 500 to 2000 working hours. It depends on the condition of use and the environment
Greater than 150 C on lamp window. The bulb can reach 900 after a few minutes of operating
Rays emitted UV-A+UV-B+UV-C+IR
Contains mercury and metal halide potentially dangerous for the environment
Frequent ordinary maintenance: glass cleaning, periodic replacement of UV bulb, replacing reflectors, cleaning filters
ADVANTAGES OF LED
High resistance to vibration and shock
Power consumption is 60% less: thus investment cost is recovers by the user in a short time
No UV emitter to replace, No technical maintenance
Lower heat implies lower heat built up in presses
Improved safety for the operator. It does not emit Dangerous UV-C radiation
It is not necessary to dispose emitters as special waste
Almost absent maintenance cost and production downtime
