Metal Halide lighting problems
 

Hi gang!

I purchased 2 metal halide pendants 2 years ago with electronic ballasts.
One of the ballasts works (lights) 99% of the time. The other fails to
light at 3 times a week. I even tried swapping in an IceCap ballast and it
fails as well! (Not to mention 2 other replacement ballasts I had shipped
to me).

The ballasts are 175W electronic. The bulb is a Hamilton 6500K. Since so
many ballasts are consistently failing, is it likely that the bulb is just
too hard to light consistently? If so, is there a bulb someone would
recommend as a replacement?

Thanks!
