| Abstrakt: | The article discusses ways to characterize lamp/fixture combination. It explores how measurement of lumens or photometry works. An independent test was done on a fixture's absolute photometry in comparison with its manufacturer's reported data. The absolute and relative photometry of a fixture and the difference between a well-lighted and poorly lighted space is examined. |
