How many lights in total? The total wattage of all globes may exceed the switch/circuit rating? i.e. 6x 100W globes on a 400W dimmer or switch. You could possibly run two parallel sets to reduce the load, but this will decrease brightness. e.g. use (+)---switch<===:=:=:===>---(g) rather than (+)---switch---.-.-.-.-.-.---(g)
It should be noted that while PAR LED's have the form factor of traditional halogen PAR bulbs, they do not have the parabolic reflectors of traditional PAR's. The light emitting diode cannot be suspended in space, in the middle of a reflector the way a filament can, at least not yet, it has to be mounted on a board.

Evidence would suggest there is a wiring error. Recheck the wiring and all the connections - something is not connected, or is connected incorrectly. Since you claim to have tested that there is power to all the fixtures, one of two things is probably the case: There is a high resistance connection which allows you to see voltage with a tester, but which ...
PAR stands for Parabolic Aluminized Reflector, by the way. The numeric part of the number is the diameter in eighths of an inch. A PAR38 will be 4-3/4" in diameter and an R20 or PAR R20 should be 2-1/2" in diameter.
