Hey Michael,here is the M-250R1 and R2 together,the front of the R1 has a more pointed front than the R2 and the hinges are close but the R2 bottom door will not fit the R1 top housing.
Thanks for the pic
BTW, I got a 250w Probe MH (listed as MH/MV) wall pack this past Tuesday. It has a broken hinge, but works great. Also, now I have 2 Metalarcs exactly the same, just one is used more and has a blackened arc tube, but works fine. The more used Metalarc is slightly more blue, while the brand new one that came with my new Wallpack has a more incandescent tone.
Plus the hinges on teh M-250 R2 have a bump on them that prevent them from going on the M-250 R1. xD But either way both are similar in shape, just different dimensions and designs. xD
