How to measure light levels?

Hold the photometer directly in the path of the brightest beam. Move it until you find the point of maximum intensity (illumination). Keeping the same distance from the light source, move the photometer in one direction until the light intensity drops to 50% of its maximum value. Move in the other direction until you find a point on the other side of the beam with a maximum illumination of 50%. Select a new line there. Use a protractor to measure the angle between the two lines. This is the beam angle and describes the angle illuminated brilliantly by the light source. Repeat these steps to find the field of view, but mark the two places where the beam intensity reaches 10% of the maximum level.
