How Often Do You Replace Your Bulb in Your Projector?

If you are like me, you probably don’t even realize that there is a problem until you try to show a movie or slide presentation at school or work. The solution is simple – change the old bulb with the new one.

Best Projectors in USA sold today come with bulbs that last anywhere from 3000 to 5000 hours. It means that every time you switch on your projector, you risk damaging your screen or other equipment connected to it. In addition, these bulbs can get quite hot during operation, mainly if you use them for long periods.

Changing your bulb should only take a minute or two. You need to remove the old bulb and place the new one in its spot. You also need to ensure that the power supply is disconnected before performing the replacement.

Then turn the projector back on, and you’re done!
