I remember now that disconnects are not needed within sight of the motors since they are fed from VFD's (430.102(B)FPN#1). 300.22(B) almost has to apply. It allows "enclosed gasketed-type luminaries" so the sealed plastic fluorescents must be ok. It obviously makes no sense that the code doesn't allow plastic coated metal flex due to combustability concerns but lets numerous plastic fixtures be installed even though readily available jelly jars would add no possibility of smoke. The factory wired motors obviously don't have to follow the NEC as long as their wiring methods get past the UL inspectors.
