Sounds like not enough illumination.
Number one rule of film presentation. Lower your amperage. Save $$.
That doesn’t work, all that does is make the lamp difficult to strike and it also shortens lamp life as they are designed to use a certain amount of current to keep their arc consistent. They should also be rotated at 1/4, 1/2, and 3/4 of their rated life and replaced at their maximum hours. But many theaters would run way past the end life by turning up the current to get the brightness back to normal levels. And then you can get one to explode - which creates a very nice cleanup and repair (speaking unfortunately from experience).
