Can't get the damn link to work, but go to www.statesman.com and search "movies"...you'll see a story titled: Watts Up Please. Heres a sample.... "Most say the culprit of these foggy, depressed images is insufficient wattage of projector bulbs, often compounded by the ineptitude of inexperienced employees at chain theaters. Professional projectionists say screen size dictates proper bulb wattage, so the smaller the screen, the less bulb power is required to provide an adequately lit picture. Problem is, most of the chain theaters -- those operated by Regal, Cinemark and AMC in Austin -- use extremely large screens in their multiplexes, possibly without proper bulb size or bulb output. Generally, larger multiplex screens demand at least a 3,000-watt bulb but should have a 4,000-watt bulb for an optimal picture. Neither Regal nor Cinemark would confirm that its cinemas actually under-illuminate the projection in Austin theaters, though the companies provided bulb sizes at some theaters. The newly reopened Arbor, whose screens are small to medium sized, uses 3,000-watt bulbs in all auditoriums, says Regal spokesman Russ Nunley. Bulbs at Regal's Westgate run from 2,000 to 4,500 watts, although Nunley said that as a result of inquiries for this story, Regal's technicians will soon be upgrading the bulbs in three of the auditoriums to 4,000 watts. Nunley confirmed that at least two auditoriums at Westgate don't use traditional projection systems, instead using "periscope" systems, which are required when the projector sits lower than the projection portal. How it works: The picture is projected onto a mirror, which reflects it onto another mirror that reflects the picture out to the screen. A periscope system makes the image "lose brightness, focus quality, pretty much everything," says a Regal manager who asked to go unnamed. Regal inherited the periscope setups when it bought the building from AMC, Nunley says.
