Don't strain student's eyes! When they were designing this installation at Derby High School in Derby, Kansas they realized the importance of proper lighting. I.E.S. recommends between 50-100 Vertical Footcandles for chalkboards in educational facilities. These #240BXWW-AKTB wall wash fixtures mounted end to end are maintaining average light levels on the markerboard of over 75 Vertical Footcandles. You can minimize eye strain by designing consistent luminance levels (within a 3 to 1 ratio) from one visual task to another, such as looking from the notes at your desk to the board at the front of the class. |
