Testing the Light Tubes
Your Day-Light Sky comes equipped with two 55 watt
compact fluorescent light tubes and can be used in a one- or
two-light setting.
Test to see that the switch and light tubes are working
properly with these steps:
• Attach the component plug and plug in the
Day-Light Sky.
• Push the switch upwards to the yellow dot for the
two-light therapy setting. The lamp should illuminate.
• Push the downwards switch to the yellow “O” for the
one-light ambient setting. The lamp should illuminate
but at a reduced intensity.
If either or both tubes do not light up, the non-functioning
light(s) may be loose or damaged. In this event, you will
need to remove and reinstall the nonfunctioning light
tube(s) to determine the problem, as described in the
section Removing and Installing Day-Light Tubes below.
Using Your Day-Light Sky
This section explains how to remove and install the light
tubes of your Day-Light Sky.
Removing and Installing Day-Light Tubes
To reset a loose light tube or replace a burnt-out tube,
please follow these instructions carefully.
To Check and Remove a Light Tube
1. Unplug the Day-Light Sky and remove the component
plug assembly from the unit.
2. Remove the base plate from the unit, if attached.
3.
4. Gently place the Day-Light with lens facing upwards
on a flat surface.
11. Twist the light tube until one side of the bulb comes
out of the socket.
12. The other side should slide out with minimal effort.
13. Now slide out or disengage the light tube from the
retainer clip at the other end.
Gently reposition the
light head in the
packing position by
turning the light head
90° clockwise until it
stops and the lens is
facing in the same
direction as the
adjustment buttons.
Remove the four (4) screws on the
back of the unit using the included
#2 Philips screw driver. (Only 2
screws are shown in photo).
Gently remove the lens using a
flathead (slot) screwdriver to raise
the lens.
Using your hand slowly slide the
lens back to disengage it from the
three front retention clips built into
the light head casing.
Check to see if a light tube is loose.
If loose, it will need to be removed
and reinstalled. Stretch and remove
the elastic around the metal clips.
Elastics are installed for shipping
safety. If one of the elastics should
break, you can safely discard it.
Remove and discard the rubber
shipping insert at the socket end
of the light tube.
To remove the light tube, depress
the white clip in the middle of the
individual light tube housing unit.
With your other hand, grasp the
tube near the plastic base and
gently wiggle it until it rises above
the white clip.

Guidelines for Light Therapy Use
When used correctly, your Day-Light Sky can help
alleviate the fatigue and decreased activity commonly
experienced in the shorter days of fall, winter, or even
into spring. Please read and follow these instructions
carefully to ensure success.
Using Your Day-Light Sky for Light Therapy
It is best to use your Day-Light Sky at an approximate
15° angle and adjust the light head so that your eyes
are approximately in the center of the light. This is
the position recommended by light therapy experts.
Begin with a 30 minute session early in the morning if
possible. Feel free to read, eat breakfast, talk on the
phone, etc. There is no need to look directly into the
light.
NOTE: While you should face the Day-Light Sky and have
your eyes open during your light therapy session, it is
neither necessary nor recommended to look directly
into the light.
Timing and Duration of Session
For best results use your Day-Light Sky shortly after
waking, preferably before 9 a.m. A 20-30 minute session
is usually sufficient. Begin with a 30 minute session and
adjust according to your needs – whether shorter or
longer sessions are required to alleviate your symptoms.
Symptoms of Overuse
Although there are rarely any negative side effects of
using light therapy, it is possible to use the Day-Light
Sky too much. If you experience increased irritability,
excessive energy, and/or any discomfort consistently
during or after use, decrease the length of your sessions,
or move the light several inches further away from you.
Adjusting to Light Intensity
Some individuals prefer to get used to the brightness of
the light before their therapy session. This can be
achieved by turning the system on a short time before
sitting directly in front of it, allowing your eyes to adjust
more comfortably. You might also wish to wake up using
the Day-Light Sky by putting it on a lighting timer. These
are available at your local electrical supply store.
NOTE: After switching on, it takes about three minutes
before the Day-Light tubes reach full intensity.
Adjusting Sessions
After a week of use you should be able to determine
what usage schedule is best for you. Some people find
an additional 15 - 30 minute session later in the
afternoon or early evening to be helpful, particularly if
they experience a slump in energy late in the day.
For a personalized profile of your Day-Light Sky needs,
we recommend completing the free online user
assessments found at www.cet.org.
Generally, using the Day-Light Sky for anything other
than a task light after 8 p.m. is not recommended as it
may delay your onset of sleep.
Importance of Daily Use
If you miss sessions or discontinue use of the Day-Light
Sky, your body may return to its usual wintertime
doldrums. Your energy should return within a few days
of resuming use.
Using Day-Lights for Other Conditions
Increasing evidence points to the efficacy of using
bright light therapy lamps for other conditions.
Such conditions are very individual and require the
supervision and guidance of a medical professional.
WARNING: The guidelines provided in the User Guide
are applicable for the winter blues, and supporting
general well-being. Do not use the Day-Light Sky for
relief of any other type of mood disorder without
the close supervision of your doctor.
Important Information
If you are on prescribed medication, we advise you to
consult your doctor first before you use the Day-Light
Sky or any form of light therapy. Certain medicines
cannot be used in combination with light exposure.
If you have eye problems, you should consult your
doctor or ophthalmologist before you use the Day-Light
Sky or any form of light therapy. Certain eye and
eye-related conditions that may respond unfavorably to
light therapy.
If you are allergic to light or have a diagnosed chronic
skin disease, it is safest to consult your doctor before you
use the Day-Light Sky or undergo any form of light
therapy.
