distances at same exposure times may provide you with sufficient light.
Timing
Using the EnergyLight at any time of day directly affects your alertness. The best time to use it is in
the morning. Do not use the EnergyLight late in the evening. If you use within 2 hours of going to
bed, it could disrupt your sleep.
- If you find it difficult to get up each day without an alarm clock or if you often sleep in, you need
morning light. Use the EnergyLight within the first hour or two after waking up.
- If you find it difficult to stay awake in the late evening and wake up too early in the morning, you
need evening light. Use the EnergyLight before you start to feel drowsy.
- If mornings or evenings do not seem to be the problem, but you feel generally tired during the
day, then the time at which you use the EnergyLight is not as important. You can use the
EnergyLight in the morning or around midday. For example, when you wake up in the morning,
use it for 15 to 30 minutes and then again at midday or in the evening for approximately the
same amount of time. Place the EnergyLight further away from you during the evening session.
Do not use the EnergyLight within two hours of your desired bedtime or you may not be able
to fall asleep.

minutes (Fig. 3).
- At the end of the first 15 minutes, the first LED is on at full intensity and the second LED goes
on at half intensity.
- After 2 hours, all 8 LEDs light up at full intensity until you switch off the appliance.

when the LEDs go on.

writing, embroidering or handicraft while taking a light exposure and look into the light every now
and then.
