PM 1212 150w, or 1211 75w. 1211 is the recomended bulb or standard bulb, and the 1212 can be used but it puts out a lot of heat. I mostly use the 75w but sometimes put in a 150w for dark 35mm negatives.
D2 and D2V and DII all share the same lamp housing. It is what goes below the lamp housing (the condensers) that is different.
