The Bodi-Tek SAD Light has been developed to help Seasonal Affective Disorder (SAD), a condition which can affect all ages, men and women alike. Symptoms vary, and are often referred to as the “winter blues”. The lack of natural light at any time of the year may cause SAD. The Bodi-Tek SAD Light is a medically certified light box to use when treating the symptoms of SAD, which may include: change in appetite or weight, lack of energy, diminishing sex drive, body aches or pains, low self-esteem, sleep problems, loss of memory, inability to make decisions, depression/mood swings, llack of concentration/interest.
Blue Spectrum Light
Most SAD lights produce white with a spectrum of 450 nm to 700 nm. Blue spectrum light is light in the 450 nm to 500 nm part of the spectrum.
Recent studies have indicated that SAD lights using blue spectrum light technology may be more effective at treating of the symptoms of SAD as you need less light. This makes the comparison with older light box technology confusing, as lower levels of output can be equally effective.
The Bodi-Tek SAD Light peaks at 460 nm in the blue spectrum, potentially making it more effective than those using older technology but with higher lux levels.
At source, the Bodi-Tek SAD Light produces over 10,000 lux. Placing the lamp 30c m away will provide +2500 lux – making it ideal for use on your desk or next to where you reading or working.
How to Use SAD Light
Simply position the Bodi-Tek SAD Light about 30 cm away from you, directing the light towards your face, but slightly offset. Adjust the timer and brightness to suit. (It is OK to look into the light every now and then, but do not look into the light continuously). Typically 15-60 minutes of exposure a day is sufficient for most people, however, you may use your light as often as you want.
- Try to co-ordinate usage with your natural biological clock, namely between 6am and 8pm
- You can obviously use the Bodi-Tek SAD Light at other times of the day, but research has shown that morning use is most beneficial
- Use the Bodi-Tek SAD LIGHT on at least five successive days at roughly the same time, you can then repeat the programme as often as you feel you need to
How to Use
Connect the mains adapter.
Switch on by holding the On/Off/ Mode button down for at least two seconds. The lights will turn on at 75% of the maximum brightness. (See Setting Brightness)
You can adjust the brightness by pressing the + and – buttons.
When maximum and minimum levels are reached, all the lights will flash once briefly.
To turn the unit off press and hold the On/Off/Mode button for two seconds.
|Colour ||Frequency ||Wavelength |
|Violet ||668-789 THz ||380-450 nm |
|Blue ||606-668 THz ||450-495 nm |
|Green ||526-606 THz ||495-570 nm |
|Yellow ||508-526 THz ||570-590 nm |
|Orange ||484-508 THz ||590-620 nm |
|Red ||400-484 THz ||620-750 nm |
Using the Advanced Settings
By pressing the Mode button briefly you can scroll through the modes.
Any adjustments you make will be automatically saved.
When setting your preferences, if the unit is left idle for five seconds it will save any changes made, but it will no longer be in the Advanced Settings mode.
Mode 1: Setting Brightness
Pressing the Mode button once select the “Brightness Setting” mode.
The left LED will flash. Alter the initial brightness setting by pressing the + or – buttons to increase /decrease the brightness.
Mode 2: Setting the Timer
Pressing the Mode button a second time will select the timer function. The centre LED will flash. Use the + and – buttons to adjust the time.
The six central LEDs indicate the ‘on’ time in 10 minute increments from 10–60 minutes. When the seventh LED flashes, this sets the unit to run continuously.
Mode 3: Setting Fade In/Out
Pressing the mode button a third time allows you to adjust the time taken to reach your selected brightness and fade out at the end of a timed session.
The right LED will flash. Press the + and – buttons to increase/decrease the fade time (up to a maximum of six minutes). This time is indicated by the six central LEDs. If you do not require the Fade Mode please select the 7th LED.
Please note that this option is not available if the ‘run continuously’ setting has been selected in Mode Two. To finish, either leave the unit for five seconds or press the mode button again. The settings and timings are for your convenience and do not alter the treatment.
