2000 hours = 250 8-hour days
That's about 1.5 school years of school or less. Remember that as the bulb wears down, it gets dimmer and dimmer until it is very difficult to see the projected image.
The No Show button on the Promethean remotes does NOT save bulb life.
Projector bulbs cost about $150-200 per bulb! That's a lot of money.
If the district had to purchase bulbs for 80 projectors every 2 years it would cost the district about $12,000 - 16,000! Think about the things that could be purchased instead, if you conserve bulb life and make your projector bulb last 3 or 4 years or more...
There are ways to make the bulbs last. Please shut off your projector if:
- You aren't going to use it for 20 minutes or more
- You and your students aren't in the classroom
- You are leaving the building
It takes about a minute for your projector bulb to cool down and 30 seconds to turn it back on.
In these tough economic times, it is important to save money everywhere possible. Do your part! Save the projectors!
