Eye-care classroom luminaires plus dedicated blackboard lights: flicker-free, Ra90+, 5000K, at least 300lx on desks and 500lx on the blackboard, UGR no higher than 19. We issue a layout drawing per classroom and verify on site after installation.
Old fluorescents flicker, leaving students strained and losing focus
Blackboards are under-lit and back rows cannot read them
Fixtures glare directly into students eyes
Retrofits must not disrupt lessons and the schedule is tight
Eye-care luminaires with high-frequency flicker-free drivers remove ripple at source
Dedicated blackboard lights with asymmetric distribution onto the board face, sending almost nothing towards students
At least 300lx on desks and 500lx on the board, UGR 19 or lower, Ra90+, 5000K
Luminaires run perpendicular to the board and parallel to the window wall, in three separately switched rows
