Just occured to me that maybe you meant that about the nipple orientation and not what an Iwasaki 14k is. Sorry, my dumb.
There's an old ... I dunno if "urban myth" is the right way to put it, but an addage that metal halide bulbs should be screwed into their socket so that the nipple on the arc tube (that little nub thing on the glass) should be pointed upwards, otherwise you don't get the best light colour off the bulbs.
There have been studies to show that it's nonsense, but enough anecdotal evidence (i.e. people saying that it made a difference for them) that it's not complete nonsense.
I made my sockets in my 75g so that I could rotate them if need be, just to make sure my halides are always orientated that way if I can't screw them in any further.
Man, could there be any worse topic to talk about ... things that sound dirty but ain't. I'll try not to make any reference about clams and wrasses while I'm at it. Whoooops, .. um .. never mind.
