This is what they do for those aviation warning strobes on towers. In the daytime they fire at their maximum intensity, but at night they fire at a lower intensity for a much longer time. This is done to avoid hurting pilot's night vision while still marking the tower.

Nikon probably found a better way of doing the FP high speed sync. Either way, it appears to be a continuous long pulse. Max Russ,

I don't think it is pulsed. Russ Max,

I believe that the FP mode holds the flash on continuously at a lower ionization state. I don’t think it is pulsed.
