The ground testing data is translated with commonly used ground to flight extrapolation analogies from atmospheric entry maneuver\u2019s engineering into values of a night observation. This results in a meteor at an altitude of 80 km with a flight speed of 11.7 km\/s of a 34.8 mm diameter spherical meteoroid. A method is developed to determine the total luminous efficiency in the bands U, B, V, R, and I from the radiance data and the measured mass loss. For the first time, a measurement of luminous efficiency became possible for known materials. The values itself are in the range of 0.01% to 1%, which is in the range of previous studies from meteor measurements.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>S. Loehle, J.
