Classrooms provide several challenges for creating efficient and effective lighting because of the many different tasks performed in these spaces. Classroom lighting should meet the highest footcandle needs for reading, writing and other tasks, but it should also be adjustable. A flexible lighting system will provide for the needs of students while saving energy. Lamps and Ballast Upgrade Source efficacy is the amount of lumens generated per watts consumed, and it depends on the lamp and ballast working together efficiently. When used with T12 electronic ballasts, the efficacies of T10 applications are comparable to those for T8 applications.
Louvers provide superior glare control and high visual comfort compared with lens-diffuser systems.
They also can eliminate the glare reflected on computer screens. Luminaire Replacement Instead of upgrading individual luminaire components, consider the labor savings and quality improvements that may be achieved with new luminaires that feature high-efficiency components. The results will be low glare, high-efficiency, and uniform distribution. Deep-cell parabolic louvers are particularly appropriate in classrooms with computers. Because the light sources are completely shielded from view, indirect systems provide relatively high visual comfort.
