Heralux® plus, Heralux® vuv
Heralux is fused in an oxygen hydrogen flame. Heralux plus tubes are being drawn in a tool-free multi-level process. They are nearly free from bubbles and of very high quality regarding their surface.
Lamp Types:- medium pressure UV lamps
- long arc lamps
Properties of Heralux plus / vuv:- clear fused
- almost free of bubbles
- good UV transmission
- high resitance to UV radiation
