A quick search of the internet yields this information.
Unsurprisingly there are guidelines and standards for illumination levels in buildings. And 300-500 lux is the recommended light level for exhibit spaces. It is also a common light level for general interiors.
My point is that it doesn't seem to make a lot of sense to review your print under a light level that is either too low or too high compared to the average encountered in the real world (500 lux, incident reading). Otherwise your print will not really appear as intend to the general public, in your average space.
If you judge your prints at 0200 lux (incident) they may appear too bright at 500 lux (incident).
If you judge your prints at 1000 lux (incident) they may appear too dark at 500 lux (incident).
If you judge your prints at 0500 lux (incident) then they will probably appear as intended in most commercial spaces, including galleries.
Any thoughts?

The table below provides recommended light levels from the IESNA Lighting Handbook and LPD levels from the IECC 2021 (using the Space-By-Space Method for calculations). Check your local jurisdiction for other or more stringent requirements. The US General Services Administration provides lighting levels and LPDs for US Government buildings, which can be used as a guide for other types of buildings. The LPD levels should continue to drop with subsequent codes and as LED lighting becomes more energy efficient.
The required light levels are indicated in a range because different tasks, even in the same space, require different amounts of light. In general, low contrast and detailed tasks require more light while high contrast and less detailed tasks require less light.
Please keep in mind that this chart is not comprehensive. The IESNA Lighting Handbook has pages and pages of various categories. If you have a very specific need, we recommend further research.
