Solid-state illumination can reduce the total cost of ownership for projectors, advocates say—while saving the environment as well
When the Phoenix Union High School District in Arizona was looking to install projectors in every classroom within its 16 schools, district officials wanted a solution that would be easy to maintain.
Working with ImmediaEDU, an Arizona company that specializes in AV integration for schools, they chose Casio XJ-M250 projectors that run on a hybrid laser-LED light source instead of a traditional mercury lamp—providing an estimated 20,000 hours of use, or about 18 school years.
“Lamps are very expensive,” said Alexis Christensen, vice president of educational partnerships at ImmediaEdu. “If you have 50 classrooms, and the lamps are all failing at once, that’s a big unplanned expense.”
It’s also very time-consuming for staff to replace the bulbs—and properly disposing of mercury lamps isn’t easy, either.
For these reasons and more, a growing number of schools and other organizations are choosing lamp-free options when buying projectors.
