Conversion MH Question?

I was just on HTG supply and purchased a 400W HPS Kit with cooltube and I noticed that they offer Conversion MH bulbs. My question is, What is the difference between a regular MH bulb and a conversion MH bulb?

By the way, I'm really impressed with HTG. My lights were ordered and at my front door in 36 Hrs. Very Fast, Kudos to them.

Beside running on different ballasts.... nothing.

If you get a magnetic HPS ballast you can rewire to accept normal MH bulbs instead of conversion ones. If you are handy in the electric DEPT.
