A few slight changes.

D) Illumination. Illumination shall be provided for all indoor working spaces containing service equipment, switchboards, switchgear, panelboards, or motor control centers. The illumination shall not be controlled by automatic means only. Additional lighting outlets shall not be required where the work space is illuminated by an adjacent light source or as permitted by 210.70(A)(1), Exception No. 1, for switched re- ceptacles.

Any better?

That assumes there was no intent to require illumination for outdoor equipment.

Glancing at 1968 it seems that the illumination requirements were geared towards interior installations. 110.16(e).

My reasoning for is that working indoors and outdoors in regards to lighting are different.

One can reasonably assume somewhat adequate lighting inside. Day or night.

Outside one cannot. Anyone going to work on outside equipment at night would reasonably assume that adequate lighting will not be available. Best one may get is that if any is provided at all, it will be the minimum mandated by whatever code requires exterior illumination for that occupancy.
 
For want of a comma

110.26(D) doesn't seem to differentiate between indoor and outdoor.
110.26(D) Illumination. Illumination shall be provided for all working spaces about service equipment, switchboards, switchgear, panelboards, or motor control centers installed indoors and shall not be controlled by automatic means only. Additional lighting outlets shall not be required where the work space is illuminated by an adjacent light source or as permitted by 210.70(A)(1), Exception No. 1, for switched receptacles.

I have to agree with your initial take, Rob, and also with Don.

As written, only motor control centers installed indoors shall be provided illumination.

Had there been a comma between "centers" and "installed", i.e., "motor control centers, installed indoors", there might be more room for argument about ambiguity.

The real question becomes what "illuminated by an adjacent light source" means. Inside a window-less, light-less space is one thing. . . but what about starlight, or streetlights, or the neighbor's lights? Given the scale of the Universe, even the visible stars are adjacent compared to most of the far universe.
 
I could swear that there was a graphic that showed a light outside for electrical panels etc but there was an exception for residences. Maybe that was just a proposal. I cannot find that rule anywhere

Actually you were pretty close, but inside.

There used to be an exception for equipment “in dwelling units”. Never needed one outside.
There also was a FPN about no additional lighting needed if adjacent lighting was good, this was intended for interior resi also.

I believe this was what you were thinking of.

Still putting my research together.
