What Is The Working Lifespan Of Projectors?

Every projector works on a bulb or any other light source. These light sources are mortal and will die without letting you know. You can associate it with the life of a human being that can end without letting you know. However, experts say that an estimated working lifespan of a projector bulb is 2,000 hours. Some say that newer models (LED projectors) are expected to work for around 50,000 hours without replacing the light source.

It is a fact that if you buy a standard projector with a standard bulb, it will last no longer than 5,000 working hours. However, the following 5 tips will help you increase the working lifespan of your projector. 

1. Limit Your Usage

If a projector has a 20,000 hours lifespan, it doesn’t mean you can enjoy watching videos for many hours a day. Careless use of your projector will make you feel as if you have used it for 20,000 hours within a month or two. We recommend using your projector for 4 to 5 hours a day. It will not only increase the working of your projector but also help you save time. 

2. Vent Cleaning

How long do projectors last depend on how you keep them. To make sure your projector lasts longer, you have to keep it in a clean condition. Projectors have vents for exhaust and airflow. These vents catch dust and get blocked. If you don’t clean them, the projector will not take adequate airflow and will heat up quickly. This careless attitude will not make your projector work even for its guaranteed working hours. 

3. Power Supply

Projectors work on different wattages depending on their type. For example, an LED projector can work on 50 watts while a laser projector will require over 250 watts of power to work. Make sure you have enough power supply for your projector, or else it might wear out. Also, note that don’t turn the power supply ON & OFF in case you want to take short breaks. 

4. Don’t Unplug Immediately

Most of you might not know that projectors need to cool down before you can unplug them. You might ask how? Well, projectors have fans that help to cool the projector down. These fans won’t turn off until the projector’s temperature cools down. Thus, if you unplug your projector immediately after using it, stop it right now!

5. Lower The Brightness

How long do projectors last depends on how much brightness you prefer. Most people like using projectors at their peak brightness. It is because they think they’ll experience low lumens if they lower the brightness. You’ll be surprised to know that lowering the brightness will not lower the lumens that your projector generates. Believe it or not, it is one of the best ways to increase the working lifespan of your projector. 

These were the 5 easy ways that you can implement to make your projector last longer. We bet you might not be following some or all of these steps when using your projector. If you want to increase the working lifespan of your projector, make sure to follow all the steps mentioned above.
