Abstract
Turning off regular incandescent lamps when not needed is always profitable. With fluorescent lamps the case is different since turning off the lights shortens the lamp life. Take a Break is a software application for calculating the profitability of turning off fluorescent lamps.
Excluding the replacement expenses, turning off fluorescent lamps becomes economically profitable even for a few minutes' breaks. When the expenses of replacing lamps are included and assuming that the heat generated from the lamps can be utilized for heating, the break needs to exceed ten minutes in order to make the turning off the lights profitable.
However, the input data will vary from case to case. Therefore, the idea is that everyone should calculate the profitability of switching off fluorescent lamps for themselves.
