Full-Spectrum Lighting and First-Grade Classroom Behavior

Time-lapse cameras were used in a standard first-grade

classroom,

and several hyperactive children may be noted, especially the boy in the

immediate foreground

Ninety days after the regular cool white fluorescent tubes were

replaced with the new type full-spectrum fluorescent tubes with

radiation shields, there was a marked improvement noted,

and the extremely hyperactive boy has voluntarily moved up to the front

row.

He raises his hand for recognition

and is now up at the blackboard taking part in classroom

activities.

Prior to the time that this new lighting was installed,

this particular boy

had an extreme learning disability problem but quickly learned

to read within ninety days after the new lights were installed.

There was further noted a general average improvement in both the

behavior and academic achievement of the entire class.

There are, however, other factors that must also be considered.

The implications of the biological effects of light and radiation

as observed through time-lapse photography are obvious
