The light needs to enter directly into your eyes. Generally, a good position is on a desk or table at 10 o’clock or 2 o’clock. You can even position slightly higher than your eyes to mimic the angle of sunlight. Just like the sun, you don't want to stare directly at your HappyLight®, but you do need to be able to see it.
You also want to find a comfortable distance from the light. The closer the light is to you, the shorter the amount of time you will need to use the light to receive its full benefits. Many people (including most of the people in our own office) leave their HappyLight® at a distance of up to 2 feet and on for an hour or more while they work.
Just keep in mind that the farther you move it away, the longer you’ll need to use the light to feel its benefits. Think... closer = shorter time; farther = longer time.
If you have an LED HappyLight® (Touch or Lucent), your light can be positioned horizontally or vertically.
If you have the Liberty Full-Size model, you can hang your HappyLight® on the wall if you like as well as tilt the angle of the light.
