Spectroscopy ~ Turn All the Lights Off!

HOW NATURAL ARE THOSE OVERHEAD LIGHTS?

 

If you are in a school building, take a look at the overhead fluorescent lights with a spectroscope. You will see that it is not a complete spectrum which is why those lights give some people headaches. There have even been studies done that say that those lights inhibit learning. Compare those overhead fluorescent lights with an incandescent light bulb or even reflected sunlight (NEVER look directly at the sun). You will see a HUGE difference!

 

When I used to teach in a brick and mortar school, I tried to use side lamps and natural sunlight as much as possible. My My students loved not using those overhead fluorescent lights!
