How should a new light fixture be grounded if no EGC exists?

When working in an older home where grounding conductors do not exist, section 406.3(D) explains how to handle replacing receptacles. However, article 410 section V does not offer any options when replacing a luminaire.

So when replacing a lighting fixture in a home with no EGC, would the replacer (potentially a homeowner) be required to install a 250.118 compliant EGC?

See the exceptions to 410.42(B). 2008 NEC, it may be in a different spot in the 2005.

Exception No. 1: Replacement luminaires shall be permit-ted to connect an equipment grounding conductor from the outlet in compliance with 250.130(C). The luminaire shall then comply with 410.42(A).

Exception No. 2: Where no equipment grounding conduc-tor exists at the outlet, replacement luminaires that are GFCI protected shall not be required to be connected to an equipment grounding conductor.

So the easiest option would be to install a combination GFCI overcurrent device on the circuit, and leave the grounding conductor on the fixture disconnected?

The OP is about a residential structure. What if the luminaire is on the same circuit as a receptacle, in a room requiring AFCI? The built in GF protection supplied by an AFCI does not count as GFCI per code, right?

Edit: For that matter, outlets require AFCI in most residential rooms, not just receptacles.

No, the GFCI that can exist in the AFCI would not be in the 5ma range, and would not satisfy the intent. No problem of course installing the device at or near the panel, but no AFCI that I am aware of can do double duty as you are wondering.
