NEC 225.6(B) Festoon Lighting, measurement to cables or fixture

Hello everyone,

I have always installed festoon lighting in accordance with NEC 225.18(1), but we have a local inspector enforcing the minimum defined clearance to the fixture not the conductors or cables. (The fixtures hang lower than the clearance requirements but the cables are above it) From what I am interpreting this seems compliant with 225.18.. Any feedback would be appreciated!

Thank you in advance!
