Hi,
Iwasaki 250w used by reefers are known as MV conversion lamps. They are MH lamps, but they are design to operate on a MV fixture. MV are cheaper because they don't need a capacitor to start.

Iwasaki is more blue when MV ballast is used.

Ok I just got back from Albrite and they have a Iwasaki for me but there is no R designation like they mention in that article and they have no listing for another bulb, and now that I look at the pictures the bulb they have is not the "R" that we need. also they tell me it wont run on a MV ballast is this true or do they just think this.. they have no listing for the advance balast mentioned in the article also. anyone have anyother ideas whare to look?
