Yes if you are talking about conductors that will be installed in the field by tradesmen, then 402.6 does not allow fixture wires smaller than a #18 AWG. But if you are talking about a complete manufactured luminaire then you need to obtain the UL 1598 standard from UL and go by this standard. Manufactures are under a different set of rules and can have much smaller wires when applying engineered wiring. So you need to contact UL for this info.
