Actually, the Super Lume-X uses the same anaode support for all lamps...just set at different heights and rotated one way or the other. The cathode support is different for the 2500 watt lamp only.
Note, the 1600WHS is a very popular lamp. From Osram, it is XB01600WHS, from Christie, it is the CXL16S, from ASL it is the XM1600HS.
The "S" version of the 1600W lamp is an efficient lamp. As to which lamp to use (bigger/smaller)...you first have to have enough light, period. So if the numbers say 1700-watts, move to the 2KW lamp. If 1597-watts are needed, you have to make a choice...I would probably go with the 2KW lamp on that one too since the light will diminish with time, the 2KW lamp has a huge current range and the 2KW lamp generally has the best life.
But if 1400-watts are all that are needed...I'd go with the 1600-watt lamp. With smaller lamps you get less heat, which mean less focus issues and and so forth. Never just go "one-over" to defocus the lamp. You really won't get as good an image with a lamp really defocused (they don't call it focus for nothing). A properly sized lamp that is properly aligned and focused, will look best every time.
