What is an important step when changing the lamp of a projector?

• A. Immediately replace the lamp
• B. Wait a few minutes after it is turned off
• C. Use gloves to avoid dirt
• D. Ensure the projector is unplugged

Answer: (B)

The important step when changing the lamp of a projector is to wait a few minutes after it is turned off. This is crucial because projectors generate a significant amount of heat during operation, and the lamp can remain extremely hot even after the projector has been powered down. Waiting allows the lamp to cool down, reducing the risk of burns or injury to the person changing the lamp. Additionally, handling a hot lamp can lead to damage, both to the lamp itself and the projector. Ensuring a safe working temperature not only protects the individual but also helps maintain the integrity of the projector. Taking this pause also provides a moment to prepare properly for the lamp replacement process.
