Iv been offered a bucnh of RADIUM HRL80W mercury vapor lamps for very cheap price.  And I was thinking to buy them as a preparation to oncoming MV-ban. Is the quality of Radium MV lamps how good, If compared to other major lamp manufacturing? Because After the ban new MV lamps wont be available. It would be good idea to stock up good quality lamps when those still are available 

Almost any lamp made in the EU or USA ( aside from US market Alto) is a good lamp. Get them, Radium did make a fair lamp.

Radium are in fact Osram...

That is good to hear. Im gonna buy those. I post a pic once I get those. Thanks for the info
