I would agree that it might be too much. However, you most certainly want lightning to create a day/night-cycle, using a timer. They are nocturnal and they need the day to sleep and the night to be active.
Also, I would highly recommend a feeding dish made out of glass, so the food can't get out. Just letting the crickets roam freely can cause problem, sinces White's are not the most agile eaters, and spaghnum moss can cause impaction.
