I am installing approximately 420' of fencing.  I would like to utilize 16 18w post lights on the posts of this fence.  I am looking at a 500w transformer which has 2 taps.  Also I would be using 8/2 wire.  I am not sure if this will work off of a single tap or if I would need to split the run into 2 separate circuits.  I am also thinking it might be possible to switch to LED bulbs which should utilize around 1w each instead of the 18w incandescent bulbs.  Any help / advice would be greatly appreciated.
