I think you've answered the question.
Next time during the waxing lunar cycle peaking with the full moon, go outside and observe the level of illumination of the landscape. Waxing lunar light even at full moon isn't bright enough to cause photosynthesis. Lunar light isn't blue [that's just marketing ] by the way, it's white. Fauna need a period of darkness too, just like all diurnal life forms do.
