Precautions
Research shows that light therapy is very safe. However, please check
with your doctor first if any of the following apply:
You have a major eye problem or have had eye surgery;
You have been advised to avoid bright light or are taking medication
that may cause photosensitivity;
You have been diagnosed with depression or other mood/sleep
disorders. This is especially important if you are also taking medication
for this, since light therapy can also affect your mood.
A few people experience side effects but these are generally mild
(including headaches, eye strain, nausea and hyperactivity) and can
usually be solved simply by switching off the light. Over the next few
days, gradually build up the time you spend in front of it to find a
treatment time that works best for you.
Some people complain of difficulty sleeping and often this is down to
using the light too close to bedtime.
If you have any problems while using Zest, or if you’ve been using the
light for a week but haven’t noticed any benefit, please contact Lumie or
speak to your doctor.
IMPORTANT: the guidelines in this leaflet are not medical directions for
treating any condition. If your doctor has suggested using light therapy,
follow their instructions and discuss any effects with them.

Introduction
Lumie Zest combines two functions in one convenient product: a wake-
up light with a sunrise alarm to wake you naturally, and a SAD and
energy light, to provide you with the bright light your body needs in the
dark winter months.
Its compact design makes it suitable for use at home, in the office or to
take with you when you’re travelling.
Wake-up light
Lumie Zest wakes you with a sunrise that naturally helps to regulate your
sleep and wake patterns. You’ll wake up in a better mood, find it easier
to get up and feel more energetic during the day.
Ideally, you should use the wake-up light all year round to help keep
your sleep and wake cycles on track.
In clinical trials, ‘dawn simulators’ such as Zest have been shown
to improve mood, energy, productivity and the quality of sleep and
awakening. They can also help sufferers of SAD (Seasonal Affective
Disorder) and winter blues cope with dark winter mornings.
SAD and energy light
Zest’s light therapy function will provide you with the bright light your
body needs during the dark winter months. It can help to boost your
energy levels, put you in a better mood and make you feel more awake.
Light therapy is safe and is proven to help alleviate the winter blues and
SAD.
Our circadian rhythms are strongly influenced by light and the short
wavelengths around the blue part of the spectrum are known to be
particularly important. Because the white LEDs used in Zest are rich
in blue light, they offer an effective alternative to the white fluorescent
tubes used in larger lightboxes.

Introduction

ENG 5
Please read these instructions carefully to get the most out of your Zest.
Features
Zest is supplied with some recommended settings for getting started; all
you need do is set the current time and the time you want to wake up.
The default settings are:

preferences. For example, you can choose:
An alarm sound in addition to the sunrise to help you wake up.
A shorter 15-minute sunrise and a choice of final sunrise brightness.
A clock display that is off or stays bright at night.
A light therapy session of between 1 and 99 minutes.

ENG 9
Using Zest as a SAD and energy light
When to start light therapy
Start light therapy as soon as you feel the early signs of winter blues
or SAD – often in September or October – if you start to feel lethargic,
anxious or irritable. You should notice positive benefits after using Zest
for three or four days in a row.
Use light therapy every day, but if the weather is bright you may feel you
can skip a day. As spring comes around you will probably start to cut
back your light therapy; your body will tell you if it’s too soon and if you
notice your symptoms returning simply use your Zest again for a few
days.
Light therapy is proven to put you in a better mood, to boost alertness
and to help you feel more awake so Zest is ideal for use at work. Use
it wherever and whenever you need to restore concentration and give
yourself a mental boost.
What time of day?
If you’re using Zest to help with the winter blues or SAD, bright light in
the morning has been shown to be most effective.
If you feel lethargic in the afternoon, or fall asleep too early, use Zest in
the late afternoon/early evening.
It’s best to avoid bright light too close to bedtime - within about three
hours - as you may find it difficult to get to sleep.
Once you’ve found a pattern that’s right for you, try to use it around the
same time every day.
What settings?
If you use Zest at about 50 cm/20 in, as suggested, then a 20-minute
light therapy session at 100% brightness is the recommended standard
for effective SAD treatment. If you’re more comfortable with the light
at less than maximum brightness then the length of your session is
automatically adjusted to ensure you benefit from your light therapy.

The following table shows the alternative combinations of brightness
setting and session duration:
Brightness
setting lxoooo lxxooo lxxxoo lxxxxo lxxxxx
Session
duration t90 t50 t30 t25 t20
Note: If you find yours eyes ache slightly, try reducing the brightness or
switch off for a while.
To position Zest
Remove the stand from the recess at the back of Zest.
Clip it into the slot on the back of the product:
Position Zest at arm’s length (about 50 cm/20 in).
Use the stand to angle the light towards your face so the light reaches
your eyes, but avoid looking directly at the light.
You can use Zest whilst you’re on the computer, when you’re watching
TV, at mealtimes, etc. Dark glasses, tinted lenses or closing your eyes
will all limit the effects of light therapy.

Frequently asked questions
I tried out the sunrise but the light comes up really quickly
– what’s wrong?
You probably didn’t allow enough time for a full sunrise. For example,
the default sunrise takes 30 minutes so if the clock shows the time as
11:00 then you need to set the wake-up time to at least 11:30.
What happens when I unplug my Zest or there’s a power cut?
Your Zest keeps time for 30 minutes; other settings are permanent, so
you won’t need to reprogram the unit, just plug it back in. If you need to
adjust the time, see Current time in Wake-up light options, page 13.
The display panel is too bright when I’m trying to sleep; how can
I change it?
See Display brightness in Wake-up light options, page 13.
How do I restore the default factory settings?
Turn off the power at the mains. Press and hold menu as you turn the
power back on. Release the button when the software version number is
displayed.
