they said that you have to use a MH balast.. that a MH bulb will run in a MH balast only.. but I was on the Iwaska page and they even say there NOT to use a MH ballast... so I will have to not tell them what I want .. so the only difference between the two bulbs is a UV shield? do we need that? I found a better drawing of the two different bulbs.. looks like a lot of difference besides a uv shield.. the "R" one has a carbon resistor and the other doesent..
