This category contains data for calculating CO2 emissions associated with indoor lighting. There are two entries: one is for a typical tungsten-filament light bulb and the other is for a typical low energy light bulb.
To use this category, specify the light bulb type using the type drill option. Next set the quantity of light bulbs used. For 'normal' light bulbs, set this quantity using the noOfLightBulbs profile item value. For lower-energy light bulbs, use the noOfLowEnergyLightBulbs profile item value.
The returned amount represents CO2 emissions associated with typical usage of the specified quantity of bulbs.
