I am looking to find out if there is a limit to the length of a fixture drop supported horizontally between junction box and fixture?
Thanks,

What is the definition of TAP in this context? I thought a tap involved conductors with lower ampacity than the overcurrent protection?

Feeder Tap Rules
10-Foot Feeder Tap Rule [240.21(B)(1)]
Feeder tap conductors can be run not over 10 ft without overcurrent protection at the point they receive their supply, but they must be installed in accordance with the following requirements: Figure 1
(1) The ampacity of the tap conductor is:
1 Not less than the computed load in accordance with Article 220, and
2 Not less than the rating of the device supplied by the tap conductors or the overcurrent protective device at the termination of the tap conductors.
(2) The tap conductors do not extend beyond the equipment they supply.
(3) The tap conductors are installed in a raceway if they leave the enclosure.
(4) The tap conductors have an ampacity of no less than 10 percent of the ampacity of the overcurrent protection device from which the conductors are tapped.

Factory supplied pigtail is OK. 404.XX something, something limits the use of SO in place of permanent wiring.

With SO it might even need a tensioner , strain relief or whatever its called the is designed to keep it from coming loose.

This is the section I had rattling around in the back of my head. It does not say you have to use a factory supplied cord but it does place restrictions on having a remote j-box. In regards to the OP I guess the cord can be as long as it needs to be as long as the box is directly above the light fixture.
It does have a requirement for a strain relief, but I have no idea what the last sentence means.
