I recently purchased a Lightphoria 10,000 Lux Energy Light Lamp by Sphere Gadget Technologies to try doing light therapy in the mornings at my desk. I usually arrive at work between 7-7:30am when it is barely light outside, and frequently don’t get outside again until I leave after sunset in winter.
Because I’ve done research on light box use I was aware that distance from the light makes a big difference in whether or not you get the expected dose. I have a SunSprite Wearable Light Tracker which measures light intensity. I hung this on my glasses next to my eyes and experimented with placement of the Lightphoria. What did I find?
