Try not to use a PWM controller for a light box. Pulse Width Modulation turns the LED's on and off for periods. This could be picked up by the camera sensor especially if the camera shutter operates quickly.

What is really required is a current limiting power supply which is more expensive but allows the LED to remain on and not switch on and off.
