Projector Bulb Life Expectancy

Many teachers use the projectors daily and they are great resource to display media and connect with the visual learners in our classrooms. So how do we get the most out of the expensive bulb inside? Each bulb has an average life of 4,000 hours. This may seem like an eternity but when they burn out it can really throw a kink in our lesson plans. Freezing the projector or pressing the A/V mute button on the remote still drains the hours on the bulb. Turning the projector off when they are not being used is the only way to ensure that your bulbs life is spent on instruction time.
