This research aims to study the intensity of light output and lamp performance in the classroom. To find ways to improve the lighting intensity of the light is not within the standard by measuring the light in the common areas. (Under Regulation Sets the standard in the management of safety, health and environment to work on heating, lighting and sound set the standard 2549. The average standard lighting common areas, classrooms lecture in the range of 300 - 500 lux).
Hits 80 buildings total number of rooms 24 found that classroom lectures with light intensity within the standard in the range (311 - 485 lux) of 22 rooms representing 91.67 classroom lectures with different light intensities above the threshold. The standard is in the range (502-518 lux) of were 2 rooms percent and 8.33 measure the light intensity of the engineering building has 37 rooms. The measurements found that classroom lectures every room. The light intensity is higher than the standard (512 - 1113 lux).
The result of the comparison of the performance of the lamp lighting through the use, for a period of 3 years in a classroom lecture in honor of 80 years found that the lighting efficiency of the bulb has a lower value. 20 rooms and lighting performance of the light bulb with a higher value. Number of 1 room.
