But theoretically I would think that even tho the lamp doesn't strobe but if u have a video with constant strobe like effects and images that go from completely dark and then to full brightness in a short amount of time, it would stress the lamp more? Cuz at the end of the day the lamp would generate more heat as it goes to full brightness and cools down a bit when it goes to total darkness/ as dim as it can. So you'll hv a constant constriction and expansion for period of time, therefore smth is more likely to break/crack no?
For example, you hv two identical pjs. One plays a static medium lit image and the other one plays a video that constantly strobes. Should the both lamps last the exact same time?
