Fluorescent or Incandescent Light Bulbs
When To Turn The Lights Off
article by Jim Hoyle
Saving money is always in style. You can save regularly by developing good
habits regarding your lighting use. You hurry into a room, flip on the light
switch, grab something you need then leave the room. Should you leave the light
on if you plan to return shortly ?
That depends on the bulb type and how long before you will need the light again.
If the bulb is a fluorescent type, leave it on if you will need it again within
20 minutes. If the bulb is an incandescent bulb, turn it off when not in use for
over a few minutes.
This is based upon the fact that incandescent bulb life is not significantly
effected by turning it on/off whereas the fluorescent bulb life is reduced each
time it is turned on. Additionally, repeated starting of fluorescent ballasts
reduces the fluorescent life span as well as uses more energy.
Use the above information in planning the lighting fixtures for your home or
office. If you need a light source in a room which will mostly be used
sporadically or for short periods of time then you should consider an
incandescent style because it will be more economical. Closets, storage spaces
and similar areas are perfect candidates for incandescent lighting.
