A lower level still has light. Note plants do not do well in darkness, as they derive their energy from the light. Some will tolerate a lower level but would thrive in levels above this. Best to not water as heavily in too low of light and make sure there is plenty of airflow for the plant to completely dry out in this condition.

Indirect light that is bright enough to read without turning on a lamp.
Light - High
Bright indirect light (could wear sunglasses at this level.)
Light - Sun
