How do I know if my projector lamp is blown?
How to tell if the lamp has blown? most certainly should not be the lamp, those are usually 2000hrs before failing. Anyhow you can check the lamp with a multimeter on the ohm scale and check for continuity. Thank you. I will give that a try. It is xenon type bulb , there is no continuity betwen it’s terminals , it works at high voltage.
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.
Do projector bulbs lose brightness over time?
Projector lamps will dim down to 50% of their original brightness as they age. Some projectors allow you to check the number of hours your lamp has been used through the built-in menu system. Check your user guide for information about this feature.

How long can a projector run continuously?
How long should my projector lamp last for? All projector lamps have an expected operating time, called lamp life. This value is expressed in numbers of hours, and is typically around 1,500 to 2,000 hours. Newer models claim 5,000 hours of lamp life and more.
Can a projector replace your TV?
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.
