Calibrating the Sun's Light.

(written by Dr. Jim Sweitzer)
We establish a way to compare light intensities from the Sun and a "home-made" light source, we measure the luminosity of the portable light source as a function of solar luminosity, (this assumes we know the distance to the Sun), and we begin to attack the problem of filters and measuring only a certain band of the Sun's spectrum.

(written by Dr. Jim Sweitzer)
We calculate the power radiated by a regular light bulb and the Sun.
