Classroom Lighting Guide

Classroom lighting supports reading, screens, and board work while controlling glare and helping students stay attentive across a long day.

Area Target
General classroom 300 to 500 lux
Teaching wall / board 500 lux vertical
Lecture hall 300 to 500 lux, dimmable
Reading / library 300 to 500 lux
Corridors 100 lux

Boards, screens, and control

Light the board vertically so it stays legible, and keep uniformity around 0.6 across desks. Neutral 3500 to 4000 K with CRI 80+ works well; avoid glare on student screens.

Daylight plus dimming saves energy, and a projection scene that dims the front of the room keeps screens readable.

Switch the board separately. Put board and teaching-wall lighting on their own switch so it can stay on when the room dims for a projector or screen.

See the Recommended Lux Levels and the Fixture Spacing Guide.

Lighting a classroom

Classrooms target around 300–500 lux on desks, with even, low-glare light that supports reading, screens, and board work. Avoid fixtures reflected in monitors or whiteboards, and give the board wall separate control so it can be lit without washing out a projector. Higher CRI (80+) helps color tasks and keeps the room feeling natural. Many schools favor neutral white (3500–4000K) for an alert but comfortable feel, and dimmable or tunable systems let teachers shift between presentation and reading modes. Good uniformity matters as much as the level, so no student sits in a dim corner.
