Read all instructions before using the Day-Light
Safety Precautions
1. As with any electrical device, do not use the Day-Light in or
near water.
2. Do not overuse the Day-Light. Recommended usage is
20-30 minutes each morning. Overuse may cause irritability,
excessive energy, or difficulty falling asleep at bedtime.
3. It is not necessary to stare into the light. Feel free to read,
work, eat or talk on the phone during your light therapy
session. See page 6 for correct positioning.
5. During the first few uses, your Day-Light may give off an
odor; this is harmless. This will not affect the use of your
Day-Light and will quickly disappear.
6. Do not leave your Day-Light on for more than 60 minutes in
Therapy mode. Always use in a well ventilated area away
from other heat sources and ensure that the air vents are
not blocked when the product is in use.

Lamp Head.
WARNING: The locking tab (3b) must be fully
engaged as shown to prevent the Arm and Base
from detaching from the Lamp Head and causing

Test the Light Tubes
Your Day-Light uses three 36 watt compact fluorescent
light tubes and has a two and three light setting.
The center switch position is OFF.
For therapy, slide the switch UP.
The lamp should illuminate with no
gaps (3 bulbs on). Slide the switch
DOWN for the task setting. The
lamp should illuminate, but at a
lower intensity (2 bulbs on).
If any tubes do not light up, one or more may be loose or
damaged. You will need to remove and reinstall the
nonfunctioning tubes to assess the cause of the issue.
Removing Light Tubes
1. Unplug the Day-Light.
2. Remove the 2 screws on the
bottom of the lens first (H)
and 2 screws on the back of
the light head (I) with the
Philips screwdriver.
3. Gently remove the lens
being careful not to
damage the 2 lower prongs
- see image “O”.
4. If the light tube is loose
remove shipping elastics
around the metal clips and
discard (J).
5. Remove and discard the
rubber shipping insert at
the socket base of the light
tube (K).
6. To remove the tube,
depress the white clip in the
middle of the light housing
unit (L). With your other
hand, grasp the tube near
the plastic base and gently
wiggle it to raise it above
the white clip.
7. Twist the light tube until
both sides of the base
comes out of the socket.
8. Disengage the light tube
from the retainer clip (M).
To Install a Light Tube
1. To re-install the light
tube, hold the tube
horizontally and slide
the top end into the
retainer clip.
2. Then gently slide the
tube prongs into the
socket. When it is
fully in place you will
hear a ‘click’ (N).
3. Once the light tubes
are installed correctly,
plug the Day-Light in
and check that the
tubes illuminate in
each switch position.
If working, unplug and
continue to the next step. (If not, try again before
determining that there is another problem with the
light.)
4. Replace the polycarbonate lens by sliding the two
prongs on the bottom of the lens into the back
housing case (O).
5. Reinstall the two back screws and then reinstall the
two bottom screws. Do not over tighten as this
could result in stripping the screws and sockets.
Light tubes are rated for 8,000 hours of use, but we
recommend replacing the tubes after two (2) years of
daily, seasonal usage.
All fluorescent light tubes deteriorate over time and LUX
levels gradually decline. Regular replacement will ensure a
10,000 LUX intensity for your light therapy sessions.

Adjusting the Light Mode
High Intensity Setting - Therapy Mode
Slide the switch “UP” and the Day-Light emits
10,000 LUX of light at 12" -14” from the lamp - the
maximum light level recommended by experts. Do
not use your Day-Light for more than 60 minutes
per session in Therapy mode.
Low Intensity Setting –Task/Ambient Mode
Slide the switch “DOWN” and only 2 bulbs light,
emitting 7,000 LUX at 12" - 14” from the lamp. We
recommend moving the Day-Light further away or
angling it down over your work area for non-light
therapy purposes.
NOTE: After switching the Day-Light on, it takes
about three minutes before the light tubes reach full
intensity.
Adjusting Light Angle and Height
For optimum light therapy usage, you will now need
to adjust your Day-Light so that:
 Lamp head is angled at about 30° from vertical;
 Eyes face the approximate center of the lamp.
Angle of the Light
To set the angle of the lamp at about 30°, press the
silver button (1) at the top of the Arm, while
supporting the Lamp Head. Release the button
when the desired angle is achieved.
Height of the Light
Press the lower silver button (2), while supporting
the Lamp Head. Lift or lower the Lamp Head to the
height that works best for you and release the
button. Support the Lamp Head as it locks into
position.
NOTE: Face toward the Day-Light with eyes open
during therapy - it is not necessary nor
recommended to look directly into the light.

The Winter Blues
Timing and Duration of Session
For best results use your Day-Light soon after
waking, preferably before 9 a.m. Begin with a 30
minute session and read, eat breakfast, etc. during
therapy.
Benefits usually take a few days to appear. Since
each persons response varies, 30 minutes may not
produce the desired level of therapeutic response or
may cause unwanted side effects. Studies have
shown that up to 85% of those who try bright light
therapy have a clinical response.
Based on your response, tailor the session time, up
or down, in five minute increments to find the
optimal session length. We recommend that your
don’t use therapy mode for more than 60 minutes
per session.
You may also add a short session (15-20 min.) later in
the day, if experiencing a slump in energy. However,
using the Day-Light for therapy after 8 p.m. is not
recommended as it may delay your onset of sleep.
Adjusting to Light Intensity
Some users prefer to adjust to the brightness before
therapy sessions. Turn the lamp on just before
sitting in front of the lamp, so your eyes can adjust
to the bright light.
Daily Use
If you miss a session(s) or discontinue use of the
Day-Light, your body may return to its usual
wintertime doldrums. Benefits should reappear a
few days after resuming use.
Other Conditions
Increasing evidence demonstrates that using bright
light therapy lamps may also help alleviate jet lag,
shift work adjustment, improve sleeping patterns
and ease low energy.
Waking Up to the Day-Light
You can also wake up to the Day-Light by using a
properly rated lighting timer.
Symptoms of Overuse
There are rarely negative side effects of using light
therapy, but it is possible to overuse the Day-Light.
If you experience increased irritability, excessive
energy, and/or any discomfort during or after use,
decrease the session length or move the light
further away from you.
