We have been using the pE-300white for several months now. This unit is amazing, and our technicians love the ease of use. From installing it to the ability to isolate light channels with a push of a button, has made out lives easier. The unit takes up less space than mercury burners, you don’t have to worry about the burner lifespan, and the heat produced by mercury burners. This unit is compact and the control box has a small footprint to maximise space around work area. If you haven’t tried this light source, you need to.
