Light better and to get an overview of your wakeup habits.
2. The Wake-up Light
2a. How it works
The Philips Wake-up Light gently prepares your
body for waking up during the last half hour of
sleep. In the early morning hours our eyes are
more sensitive to light than when we are awake.
During that period the relatively low light level of a
simulated natural sunrise prepares our body for
waking up and getting alert.
Clinical research shows that people who use the
Wake-up Light wake up more easily, have a better
overall mood in the morning and feel more
energetic. Starting the day with the Wake-Up Light
may also have a positive effect on your
productivity throughout the day.
Position the appliance on your nightstand at 1620in/ 40-50 centimeters from your head. Make
sure the appliance is located at such a height that
the light is not blocked by your bed, comforter or
The 20 light intensity settings allow you to use the
product as a bedside lamp, whether your iPhone is
docked or not. You can change the light intensity
by pressing the Light + and - buttons even when
the light is off, so you can decrease the intensity
before turning on the light if you need to get up
and find your way in the middle of the night.
The battery of your iPhone or iPod Touch charges
automatically when it is docked in your Wake-up
The time of your Wake-up Light will be set by the
clock of your iPhone. If there is a power failure,
your alarm time is stored in your iPhone, so if the
app is running you will always be notified at the
set alarm time.
You can use the Wake-up Light speaker to listen to
music at any time of the day with the iPod
function of your iPhone. The speaker of the Wakeup Light will automatically turn on when you play
music from the iPod function, but it may not turn
on automatically with other audio apps. You can
always turn the speaker on and off manually with
the sound button on your Wake-up Light. The
speaker icon on the right-hand side of the display
of your Wake-up Light indicates if the speaker is on
(icon is visible) or off (icon is hidden).
2b. Wake-up function
The light of the Wake-up Light gradually increases
for 30 minutes before the set alarm time,
mimicking the colors of a sunrise from deep
morning red to bright daylight. For example, if you
set your alarm time at 7:00, the light of the Wakeup Light will gradually start to get stronger after
6:30 so that by 7:00 the light is at its brightest and
you wake up. You can adjust the sunrise duration
from 20 to 40 minutes to your preference.
Because the sensitivity to light differs per person,
you can set the light intensity of each alarm to a
level that matches your light sensitivity for an
optimal start of the day. The light intensity of the
Wake-up Light can be set up to 250 lux. You may
have to experiment with different settings for a
few days to find your optimal level. See the page
“Optimize your settings” for more information.
The duration of a natural sunrise varies with the
seasons and the geographic location. Most people
find that a 30-minute duration is good to prepare
their body for waking up in the morning, but if you
are very sensitive to light you may choose 20 or 25
minutes for the sunrise duration.
At alarm time, you will start hearing the selected
natural sound or the selected music from your
iPod library. It starts quietly and takes 90 seconds
to reach the volume level you selected. The
gradually increasing sound will make the wake-up
process even more pleasant, ensuring that you are
never woken up roughly.
Thanks to Smart Snooze, you can put the Wake-up
Light into snooze mode by tapping the product.
After 10 minutes (or a snooze time of your choice)
the sound will start playing again gently. The light
remains on during snoozing, just like a natural
You can stop the alarm by pressing the Sound
on/off button on your Wake-up Light or by simply
undocking your iPhone. The lamp stays on to give
you the opportunity to get out of bed without
switching on another lamp.
After waking up, you can turn off the light by
pressing the light on/off button on your Wake-up
Light. If you forget to do so, the light will
automatically turn off after 90 minutes.
In this app you can create up to 10 alarms with
fully customizable wake-up profiles. You can use
this app to wake up without the Wake-up Light. In
that case, the light function will not be available.
You will only hear the wake-up sound from the
speaker of your iPhone at alarm time.
Remember to leave the app running overnight to
ensure the Wake-up Light wakes you up at the set
alarm time in the morning. The “Bell” symbol on
your Wake-up Light is a confirmation that an alarm
is set for the next day.
2c. Fall-asleep function
Your Wake-up Light can help you drift off to sleep
by gradually decreasing the light and/or sound for
5 to 60 minutes. The light decreases from bright
daylight to warm evening light. At the end of the
set duration, the light and sound turn off
Before you start the fall-asleep function, turn on
the light to the level you like. The dimming will
start from that intensity. If you change the light
intensity or volume during the dimming, the light
will stay at that intensity until the end of the set
dimming time (for example to give you enough
light to read a little longer), and then turn off.
The fall-asleep function can only be started by
docking your iPhone after selecting the dimming
settings. If you undock during the dimming time,
the light will continue to decrease, but the music
will stop. Don’t forget to dock your iPhone and
leave the app open before you go to sleep to
ensure the Wake-up Light wakes you at the set
alarm time in the morning.
You can stop the fall-asleep function by turning off
the light and sound with the light and sound
buttons of your Wake-up Light at any time. Your
programmed alarms for the next morning are still
2d. The light source
The light source in your Wake-up Light is a unique
arrangement of high-power LEDs (Light Emitting
Diodes) designed to mimic the colors of a natural
sunrise from deep morning red to bright daylight
and give you the optimal wake-up improvement.
Because of the long lifetime of LEDs, the light
source in this device is not replaceable.
The high-power LEDs make your Wake-up Light
very energy-efficient: the maximum power
consumption of this appliance is 18W (when the
light is turned on at maximum intensity, the sound
is playing at maximum volume, and an iPhone is
The display of your Wake-up Light is equipped with
a light sensor that adjusts the brightness of the
clock depending on the light level in your room.
When your iPhone is docked you can choose
between 4 brightness levels. If you are very
sensitive to light at night, you can choose level 1. If
you want a brighter clock at night, you can choose
level 2 to 4. All levels go to the brightest setting
when your bedroom is well-lit.
2e. Optimize your settings
Everybody has a different way to wake up. Some
like their sunrise short and bright, others slow and
To help you wake up pleasantly every day, the
Wake-up Light offers settings to adjust the light
intensity, the sound volume and the sunrise
duration. Finding the combination that suits you is
easy if you follow these simple recommendations:
1. Start with medium levels for all settings: light level
10, volume 10, duration 30 minutes.
2. If you would like to feel more alert when you wake
up, increase the light level or the sunrise duration.
3. If you wake up too early, decrease the light level or
the sunrise duration. You can also place the Wakeup Light further from your pillow.
4. Adjust those parameters until you find a
combination that makes you feel alert at alarm
It typically takes a few days to first get used to the
Wake-up Light and then find your preferred
If you need additional reassurance, you can set a
backup alarm in this app with a louder volume.
For example, set your main alarm for 7:00 with
light and sound, and a backup alarm at 7:30 with
sound only. The backup alarm will ring even during
a snooze period.
2f. Troubleshooting
Q1. Which Apple products can I use in combination with the Wake-up Light?
A1. You can use iPhone 3GS and above, or iPod touch 3 and above. Make
sure that you at least have iOS5 installed.
Q2. Does the Wake-up Light work without an iPhone/iPod?
A2. No, The Wake-up Light only works in combination with an iPhone or
iPod touch. Without an iPhone/iPod touch you can only use the Wake-up
Light as a normal lamp.
Q3. Sometimes I get a message: "Wake-up Light would like to communicate
with the Philips wakeuplight; allow - ignore". What does it mean?
A3. This means that the Wake-up Light wants to communicate with your
iPhone/iPod. Please choose allow, to be able to control the Wake-up Light
with the app. If you choose 'ignore', the app will not start.
Q4. The app does not always start when I dock my iPhone/iPod. What can I

3. Wake-up Stats
3a. Why this feature
The Wake-up Stats menu will help you use your
Wake-up Light better by observing how your body
reacts to light when you try different settings. The
way you feel in the morning can be improved by
using the Wake-up Light, but it is also influenced
by the quality of your sleep during the night and
the duration of your sleep.
This feature provides an easy way to keep track of
your habits and visualize your behaviors. To feel
at your best throughout the day, it is important to
balance a good night’s sleep, physical activity and
sufficient light exposure during the day. Regular
sleep and wake patterns help your body to
function optimally.
By keeping a Wake-up Light diary, you can
recognize patterns, understand why you feel
better on some mornings than on others, and
make choices for a healthy lifestyle. Because the
information is recorded by your Wake-up Light,
you do not have to enter your bedtime and wakeup time yourself, which makes this feature easy to
For your privacy, all of your information is stored
in your app only, and it is not shared with Philips or
any other party.
Stay tuned for improvements to this app, as
Philips continues to work on this feature. If you
have suggestions to improve the Wake-up Stats or
this app, please send us your feedback via the
“Contact Us” link in the main Help menu.
3b. What is measured
The Wake-up Stats only record data when your
iPhone is docked and the app is running.
Therefore, docking is the beginning of the time line
on the summary page and undocking is the end of
the time line.
Each night, the system records if you use the fallasleep function or if you simply operate the lamp
manually. In the morning, your wake-up settings
and number of snoozes are memorized.
Recording these events is optional, and you can
choose to disable this feature in the Settings
menu. This information is stored in your iPhone for
six months before it gets deleted permanently.
In the morning you can choose to answer two
questions and write a personal note:
1. Rate the ease of getting up
2. Rate the quality of last night’s sleep
3. Indicate if something happened last night (free
These values allow you to track how you feel in
the morning, and help you to understand how the
Wake-up Light works for you. Answering these
questions is completely optional. You can enable
or disable them anytime in the Settings menu.
You can answer the questions about your waking
up and sleep any time on the day following the
night by clicking “Questions” in the top right-hand
corner of the weekly summary, but it is most
accurate if you answer them within the first half
hour after waking up.
Keep in mind that this integrated Wake-up Light
diary does not actually record your sleep but your
routines. You may be in bed with the light off but
not necessarily sleeping, or your mobile device
may be docked long before your bedtime. If this
happens you can record this in the personal note
3c. How to use the results
The summary page visualizes your bedtime routine
in the last week of use. You can swipe up or down
to load other weeks. Every line represents a night
when your iPhone was docked. You can also swipe
left and right to see additional hours if the bar
doesn’t fit on the main screen.
You can tap on a time line to get a detailed view of
that morning. On this page you can find more
information about your wake-up and docking
behavior. Swipe to the right to find the exact alarm
settings you used that day, and the last page is the
notes you may have written yourself if you enabled
the morning questions.
Under the “Graphs” menu in the top left-hand
corner of the summary page you can find
additional graphs to help you visualize your
3d. Healthy bedtime routines
To perform and feel well every day, we need to
have a good balance between activity and rest.
Our activities during the day and our environment,
both influence our sleep quality and the sleep
quality in turn influences how we feel the next day.
Our body generally likes regular patterns. For a
healthy bedtime routine, make sure to go to bed
and wake up around the same time every day, with
less than 2 hours of variation on days off.
Many people stay up late on evenings before days
off. A large variation in bedtimes between
weekend days and week days not only makes it
more difficult for them to function at the beginning
of their work week, but it also affects their sleep
and other lifestyle habits. For example, eating at
the wrong time of the day may have short- and
long-term consequences on weight and mood.
Adjusting the timing of light exposure and
introducing a natural dawn and dusk experience
into our lifestyle can help to achieve and sustain a
healthy lifestyle.
A variety of behaviors related to lifestyle may
significantly influence sleep quality and sleep
quantity. Sleep experts recommend the following
habits for a good sleep hygiene:
Try to avoid caffeine at least 4 to 6 hours
before bedtime
Exercise regularly, but not late in the evening
Try not to drink alcohol 2 hours prior to your
If you do need to nap, take short naps (30-40
minutes) and preferably before 4PM.
Maintain regular schedules for meals and
choose the right balance for food and fluid
intake in the evening
Make your bedroom a sleep-inducing
4. Well-being by light
4a. Light and a Healthy Lifestyle
Visible light plays a very important role in human
well-being. All plants and animals on Earth have
developed mechanisms to anticipate the time of
day based on the cycle of light and darkness, and
we are all synchronized to this cycle by means of
light entering our eyes. The regularity of this cycle
influences our functioning throughout the
day.Changing the timing of especially the start and
the end of the light exposure will influence our
feeling of well-being: early bright light will make
you energetic in the morning, whereas late bright
light will make you energetic in the evening.
4b. Light and alertness
Bright light entering our eyes increases our
alertness and decreases sleepiness. This is the
case during the day and during the night. In the
morning, when the eyes are still adapted to
darkness, relatively moderate light intensities
(such as the ones of the Wake-up Light) can be
sufficient to activate the body and reduce
sleepiness. During the day one needs to seek much
brighter light to increase alertness, such as the
light provided by the sun or Philips light therapy
In the case of the Wake-up Light, the gradual
increase of light intensity before awakening gently
prepares the body for waking up and has the
additional effect of reducing sleepiness.
4c. Light and sleep
In modern society we have the capability to
prolong the light part of the day by using artificial
lighting. Our bodies are not synchronized to the
rhythm of the sun, but to our lifestyle. Many
people extend their daily activities towards the
evening, delay their bedtime and, in case of work
or school obligations the next day, shorten their
sleep. Insufficient sleep has an impact on daily
functioning, and it is often only in weekends that
people try to compensate for their shortage of
Reducing the amount of light during the last few
hours before bedtime, and exposure to bright light
in the early morning hours can support the timely
onset of sleep and bring about more alertness and
energy right from the start of the day.
By maintaining a regular lifestyle with only small
variations in bedtimes, sufficient light exposure
during the day, low light exposure during the
evening and darkness during the night, you can
achieve a good balance between rest and activity
and reduce a variety of health risks.
4d. Light and mood
In countries with long winters, many people
experience loss of energy and low spirits due to
lack of light. This phenomenon is known as the
winter blues. Daily exposure to a ‘light bath’ from a
Philips light therapy product can restore the wellbeing and energy levels that you feel in summer.
Two types of products are available: Philips
EnergyLight uses bright white light, and the more
innovative and portable Philips goLITE BLU uses
blue light.
4e. Clinically proven benefits
It has been clinically proven that waking up with
light improves your well-being. Several studies
have shown that the Philips Wake-up Light truly
improves the quality of waking up.
