What Is A Light Box? Introducing Light Boxes And Light Therapy
When I tell people I maintain a website about light boxes, the
response I often get is: "What exactly is a light box?"
In the simplest terms a light box is a type of light that uses a
low-watt diffuse bulb to spread light throughout a small
translucent box. They have several different uses.
In art, a light box is used for stenciling, transferring designs
or patterns, or tracing. For example, if you've ever gotten a
tattoo, the tattoo artist may use a light box to trace out the
pattern you've chosen or drawn for your tattoo with transferable
inks, allowing him or her to transfer the pattern to your skin
as a guideline before they start drawing on you. Or comic book
inkers may use a form of tracing for their art finishing in
comic books and graphic novels.
Photography uses light boxes for looking at negatives and
slides. With a light box to lay small transparent images on to
view, the photographer has a much easier time figuring out what
images he or she wants.
Other uses include stained glass design, embossing, quilting,
calligraphy, or lettering. Basically, any purpose that requires
a form of tracing to transfer artwork from one medium to another
can use a light box.
Light Therapy: The Most Popular Use for Light Boxes
Because a light box delivers diffuse, non-straining light in a
variety of wavelengths, light boxes are sometimes used to treat
Seasonal Affective Disorder (SAD), a form of depression
instigated by a lack of sunlight, especially in northern
climates. Not only do light boxes deliver full-wave light for
therapeutic reasons, they can also deliver UV light.
Regular light used to treat SAD can be much too bright and
intense. With constant exposure to bright light, you can strain
your eyes. The diffuse light of a light box eliminates many eye
strain problems and allows you to expose yourself to light for
much longer and with more frequency. And because light boxes
deliver light with little or no UV light, it's a safer way of
getting light therapy than exposure to sunlight.
Most light boxes that deliver light to treat SAD should
concentrate their light emission on the shorter wavelength blue
light naturally delivered by the sun. They should be cool and
diffuse, allowing you to stay close to your light box so you can
expose yourself to the highest possible amount of light.
Light boxes for SAD therapy should also be large enough to
deliver light all over the user, and make allowances for the
user's movements during a normal day. You should be able to
mount your light box on the ceiling, which will allow the light
to diffuse throughout the room and provide you with the maximum
amount of exposure when you want it throughout your day.
You should also be aware of what times of day you should use
your light box. Your therapist or physician should be able to
tell you what the ideal times are, and you can adjust its
location accordingly.
Portable light boxes are also a good idea. Hard-to-use or
inconvenient light delivery devices wind up in the closet. A
light box on a stand, with a handle so you can easily move it
around, is probably your best bet.
