GE M-250R2 With Round GE Refractor

I think this looks good with the deep round refractor. I think that this refractor was supplied with the M-250R2 for 175W MV units but the HPS and 100W MV versions used the squared refractors. I don't know why but that's what I see here. The 175W ones always have the round lens and the 100W MV ones always have the squared lens. The HPS ones all originally had the squared lenses but some have random refractors since NGrid replaced refractors if the fixture had dirt in the refractor. They could just wipe the dirt out...
