Regular maintenance

Cleaning the projector lens regularly will help extend the life of the bulb. Make sure to follow the instructions in the user manual on how to clean your specific model.

Turn off and unplug the power when not in use

When you are not using the projector, be sure to turn it off and unplug it from the power source. Turning it on unnecessarily. It will shorten the life of the bulb.

Use the economic model

If your projector model is available and appropriate for your situation, use the “Economy Mode”. This mode will reduce the brightness of the projector, but the bulb will last longer.


In fact, the projection brand, model, projection quality, and the projector hardware itself are the factors that affect the life of the bulb. In life, if you take care of the projector headlight, its life span will be relatively extended. If you are a regular projector user, LED bulbs will be your best choice.
