I didn't want to intrude on Cam's calibration thread, but do DLP bulbs get dimmer as they age, or do they maintain relatively even brightness until failure?

Seems like I can't watch a "dark" scene during daylight anymore. It's OK at night, but you just can't follow a dark scene unless the room is really dark lately.

The room lighting hasn't changed....
