What should I do if the light doesn't wake me up?
When you fi rst start using the Daybreak, consider using the backup alarm or radio as part of your wake
mode settings. Be sure you are using a lamp that provides suffi cient brightness to light up your entire room.
Also, many people fi nd that increasing the duration of the sunrise helps them wake up at the right time.
What type of lamp should I use?
You should use a lamp that provides enough brightness and diff usion to light up your whole room.
Reading lamps or other focused lamps tend to light up one spot only, and you may be facing away from
that spot at the time when your body needs to start waking up.
What bulb wattage is best?
Your room layout and lamp shade can aff ect the amount of light that reaches you while in bed, but on
average, a 100W bulb will provide the best results with dawn simulation.

Should I use a special type of incandescent bulb with my Daybreak?
You can buy blue-enhanced light bulbs that have neodymium added to the glass. Th ese bulbs can be quite
expensive, but are generally higher quality (longer-lasting) and do a better job of color rendering. Th e
color diff erence between a standard bulb and a blue-enhanced bulb may have an eff ect on your results,
but studies have not been done to prove this. Most dawn simulation studies that have been done with
household lamps used 100W standard bulbs. You should consider using a neodymium bulb with your
Daybreak.
Why can't I use fluorescent lamps with the Daybreak?
Most fl uorescent lamps are not dimmable because of limitations in the electronic circuitry that powers
them. While some specialized fl uorescent lamps are dimmable, they cannot be used simulate a sunrise
accurately because their lowest intensity is about 20% of full power. An eff ective sunrise simulation starts
from nearly imperceptible levels of light and then slowly ramps up. Th is scenario is impossible with
current fl uorescent technology.
