The lighting load is dealt with in 210.70 and it can't be a receptacle.

There is no law against plugging a light into a small appliance circuit (like the pucks HOs put under the upper). it is just not a "lighting outlet".

Lighting Outlet. An outlet intended for the direct connection of a lampholder or luminaire.


It is just a receptacle someone plugged a lamp into.
