Do not use lighting for security. Vandals are deterred more by darkness than by light. In addition, when a building is dark an intruder will be tempted to use a flashlight, which will be visible through windows. When buying new light bulbs or fixtures, consider energy efficient alternatives to the current technology used.
Incandescent bulbs are a reasonable choice in fixtures that are on a very few hours per year.
For any fixture that is on a significant number of hours per year, compact fluorescent bulbs should be considered. Put up stickers reminding occupants to switch off lights that are not in use. Reduce illumination levels in overlit areas. Refer to DEC code for recommended footcandle intensity levels. Whenever tubes are removed from fluorescent fixtures, the associated ballasts should be disconnected as well.
