This sounds like the normal end-of-life for a flourescent lamp, and MH is
much the same technology. How old is the lamp? Is it a "normal" MH lamp, or
something exotic that may require a higher voltage? What kind of ballast are
you using? You might want to repost your question along with this additional
information in the sci.engr.lighting newsgroup.
