Yes, supposely some can, can't remember if they are millis, or montis. And I would say with pcs, for a nano be 96W.
This is all from memory of reading off of the Nano-reef.com forum, so I could be wrong.

P.S. Want to enlighten us on what your going for? Is this a tank you are setting up, or one already set up, is this a tank that is going to be big or a small nano? Just curious and it would help us know what you trying to do to give better advice.
