Lighting Lecture

D-Lab: Energy is a new D-Lab class, running for the first time this semester.  One of our recent class topics was on lighting, which is often what people who lack access to energy would like. To help students understand the challenges of studying and working by candlelight, the lighting lecture was taught using various forms of lighting.


First, they took a group quiz by candlelight -- one tealight candle per group of four students taking the quiz. As you can see, these were VERY challenging conditions.

We then allowed the students to use hand-pumped flashlights. That made things a whole lot easier, although it wasn't nearly as easy as typical MIT task lighting associated with quizzes.

One the quiz was over, we tried out a battery-powered camping lantern with a flourescent lightbulb.  It helped, but glare and directionality were still quite difficult and made lecturing pretty challenging too -- I made some mistakes that I blame on the extra brainpower required just to look at my notes.

Eventually, we used powerpoint, opened up windows, and even turned on the lights.  The contrasts were illuminating!
