I have been fortunate enough to have an inspection where there is an inghround pool installed some 12 years ago with no sign of equipotential bonding.
We have a game plan to address everything everything but the underwater light.
Exposing the existing light forming shell is a nightmare in it's own right.
Does anyone know of a retrofit lighting system which would allow the existing niche to not be bonded, or are we stuck with requirement of bonding due to it being metallic regardless of the lighting employed (such as fiberoptic) ?
 
Even if it is no longer an electric light, I think that 680.26(B)(5) will require the metal shell to be bonded.
 
Unfortunately, even if the metal shell has no metallic contact with lighting equipment (e.g fiber optic with remote lampholder) it could still be energized by stray voltage imposed in the earth outside the pool.
As a result, I would argue that for safety it would at a minimum need to be part of the equipotential grid even if it no longer required the more specific grounding/bonding for lights.

So there is no bonding terminal inside the pool light niche and the pool light niche isn't connected to the deck box with brass conduit?

The pool light does have the extra equipment ground internal (only a #12), but there is no connection to an e.p. grid as there appears to be no grid.
 
Wasn't this pool inspected at the time of installation? How are you gotng to create an
equipotential grid? Can a terminal lug be attached to the grounding lug inside the
lamp housing? Just trying to understand what is the situation is.
