To help determine if you have sensitivity to light treatment, we recommend that you
perform this pretest upon first use of this device:
Step 1 - Start this test with the comfort lens. Turn on the lamp and position it about
18inchesfromyourface.(Donotlookdirectlyintothelamp.)
Step 2 - Operate the lamp for approximately 10 minutes and turn it off. If the light
has caused any discomfort, stop using the lamp and consult a doctor.
If you have no discomfort, you may consider gradually decreasing the
distance from the lamp and increasing the use time, which results in
more lamp intensity and greater effect. You also may change from the
comfort lens to the high-energy lens and repeat the device pretest. For
your initial sessions, you should monitor the degree of any discomfort and
accordingly adjust the time used, lens used and lamp location.
WARNING:Somepeoplemayexperiencelightsensitivitytofluorescent
lighting. Discontinue use if you experience any discomfort.
WARNING:Certaindrugsmayinducelightsensitivity(e.g.,anti-
depressants)whichmayresultindiscomfortoralevelofhyperactivity.Consult
with your health care provider before using this product.
WARNING: If you have a pre-existing eye condition, contact your
health care provider prior to use.

Benefits
Verilux Natural Spectrum
®
light is just the right kind of illumination, easily absorbed
by the eye, efficiently cueing the body to improve mood, energy and function while
reducing light sensitivity, eyestrain and fatigue.
Unlike most artificial light, Verilux Natural Spectrum light illuminates in the broader
scotopicrange,stimulatingmoreoftheeyes’photoreceptorswithoutextreme
brightness and glare. Like daylight, this scotopically enhanced light allows optimum
visual stimulation without oversaturation.

Instructions for Use
Use consists of sitting close to the HappyLight Energy Lamp with your eyes
open. While staying oriented toward the light, feel free to engage in other
activities such as reading, writing, hobbies and crafts, sewing, needlepoint,
applying make-up or working at your computer or desk. You may tilt the lamp
as required.
Selecting a Location
• PlaceyourVeriluxHappyLightEnergyLamponatableorotherflatsurface
above, at or below eye level depending on your desired result.
• Forbestperformance,placetheHappyLightascloseas6inchesbutwithin
24 inches of your face.
• If you have sensitive eyes or want to use the highest output settings and lens,
you may find it preferable to place the lamp above you and use the tilt feature.
WARNING: This product contains magnets. If you have a pacemaker,
implantable defibrillator, insulin pump, any other type of electro-mechanical
device,orbrainshuntsthatcontainmagnets,keepsufcientdistance(about
6inches)betweenthedeviceandthelamp.
WARNING: Do not block vents. Vents are necessary for proper
function of the electronic ballast. Blocking them may cause overheating of the
electronics and increase risk of fire.
CAUTION :
Avoid placing this lamp in areas that are exposed to direct
sunlight or close to heat-radiating products such as heaters. Do not place the
lamp on top of appliances that radiate heat.
1. Turn on the lamp and allow a few minutes for the bulb
to achieve full brightness.
2. The HappyLight Energy Lamp should be positioned as
close as 6 inches, but within 24 inches of your face and
shouldbeslightlyoff-center.(Seediagram.)Note: Do
not look directly into the lamp.
3. Consider using the lamp on the high setting in the
morning and on the low setting in the afternoon.
The light from the HappyLight Energy Lamp must be
directedatyoureyes;therefore,youreyesmustbe
open to achieve the full benefit. Note: Tinted glasses reduce the amount of light
reaching your eyes.
When you are feeling sluggish and lethargic, spend more time with the light,
sit closer to it or adjust the settings to increase the intensity. If you experience
edginess or are over-stimulated, move the light farther away or reduce session
times.

Bulb Removal and Replacement
Operation — continued
Researchers at the National Institute of Health demonstrated that white light, in a
rangeof2,500to10,000LUX(ameasurementoflightintensity),helpedtoreversethe
symptoms of “Winter Blues.”
Exposure strategies affect people differently. We all have different reactions to our
environment. It is important to establish a distance and schedule that is comfortable for
you. We recommend you use the light regularly and at about the same time each day.
It is not necessary to sit in front of the lamp continuously. You can divide the time into
several mini-sessions. Continue to use the HappyLight daily to feel an improvement in
your mood and activity level.
When you are feeling sluggish and lethargic, spend more time with the light, sit closer
to it or increase the light intensity by switching to the high-energy lens. If you feel a sort
of edginess, as though you have consumed too much coffee, it may be time to turn off
the unit or reduce the intensity of the light.

DISCONNECT LAMP FROM OUTLET
PRIOR TO REPEATING THE BULB INSTALLATION PROCESS.
Sometimes when a new bulb is turned on for the first time the tube will
darken, but this will fade after a few minutes.
With older bulbs, darkening of the tube indicates end of bulb life. (This
doesn’t affect operation except to reduce the amount of light available
since the phosphor in that area has become inactive.) Bulb replacement
is recommended.
Insert plug securely into wall outlet.
Connect lamp plug only to wall outlet without dimmer switch.
Light won’t tilt Are the thumb screws
too tight?
Loosen the two blue thumb screws on the back of the unit, adjust the lamp
