Always turn off incandescent bulbs when you leave a room. Fluorescent bulbs are more affected by the number of times it is switched on and off, so turn them off when you leave a room for 15 minutes or more. You’ll save energy on the bulb itself, but also on cooling costs, as lights contribute heat to a room.
