Adjusting Light Angle and Height
For optimum light therapy usage, you will need to
adjust your Day-Light Sky so that:
• The light shines down at an angle of about 15°; and
• Your eyes are approximately in the center of the light.
To Adjust the Angle and Height of the Light
There are two adjustment buttons on the arm of your
Day-Light Sky. Each silver button, when pressed,
allows you to move the light head or arm to several
different positions.
When you wish to adjust the height or angle of the light
head, press the appropriate adjustment button while
holding the light head to move it to desired position.
To maintain the position, release the adjustment button
to lock the arm in position.
By removing your hand from the light head and
allowing it to engage, the head will properly and gently
settle to the engaged position.
To set the angle of the light at approximately 15° use the
best combination of adjustments based on where your
Day-Light Sky is positioned and your height.
When not using your Day-Light Sky for light therapy, you
can easily reposition the light head to use as a task lamp
over or near your work space.

To Install a Light Tube
1. To reinstall the light tube, hold the tube horizontally
and slide the top end into the retainer clip.
2. Next, gently slide the prongs into the light socket.
When it is fully in place you will hear a ‘click’.
3. Once the light tubes are installed correctly, plug the
Day-Light Sky in and check that the lights illuminate
in each switch position. If working, unplug and
continue to the next step. (If not, try reinstalling
the tubes again to determine if there may be a
problem with the light.)
4. Replace the plastic lens by sliding the front under
the retention clips on the lamp head housing. It
should clip easily back into place.
5. Reinstall the four (4) screws ensuring they pass
through the lens. Do not over tighten as this could
result in stripping the screws.
Using and Adjusting the Light
Intensity Settings
The Day-Light Sky operates with two 55 watt compact
fluorescent light tubes. There are two light intensity
settings on your new Day-Light Sky – a high intensity
and low intensity setting. High intensity is the recom-
mended dosage for light therapy sessions, while low
intensity may be preferred for use as a task light.
High Intensity Setting—Light Therapy
At this setting, the Day-Light Sky emits 10,000 LUX light
intensity when sitting a distance of 11 inches (28 cm)
from the light. This light level is the recommended
dosage for 20-30 minute daily light therapy sessions.
Push the switch to the side with solid yellow dot
marking. Both light tubes will be on at this setting.
Low Intensity Setting – Task or Ambient Lighting
You may prefer the lower intensity setting when using
your Day-Light Sky for work or ambient lighting – it’s
your choice. The lower setting emits a light intensity of
5,000 LUX when sitting 11 inches (28 cm) from the light.
As this is still quite bright, we recommend that you
either move your Day-Light Sky further away, or angle
the light down over your work area when using it for
non-light therapy uses.
For the lower light intensity setting, push the switch to
the side with the yellow “O”. You should see only one of
the light tubes illuminate.
Assembling your Day-Light Sky
The base plate ensures your Day-Light Sky will stand in a
stable position.
4. Carefully lift the assembled unit and stand it upright.
5. Turn the light head counter clockwise 90° for
therapeutic or task lighting.
