Why projector lamps are so expensive?

The amount of mercury in the bulb must be carefully measured to maintain the optimal pressure when it’s at full operating capacity. The complexity of High Pressure Mercury Vapor lamps, and the toxicity of the mercury used to produce them, make them expensive to produce.

An $800 projector can give you a 120-inch image, while a TV that’s 80 inches costs nearly $4,000.

Some people don’t bother with a screen — they’ll just use their wall.

How do you know if a projector is good?

The best way to determine if a projector outputs enough light to produce bright images, check the ANSI Lumens rating. This will tell you how much light that a projector can put out. Relatively speaking, projectors with 1,000 ANSI Lumens or greater have sufficient brightness for home theater use.

What is better LCD or DLP projectors?

DLP projectors provide sharp, high-quality projections with the potential for 3D capability as well. DLP projectors tend to have more mirrors and therefore more pixels to project your desired images and videos in higher definition. LCD projectors tend to be less expensive.
