  Vertical illuminance

  Assessment of circadian entrainment is based on the vertical illuminance in Lux, which falls on the cornea. Because vertical illuminance is the measure of light perception when reflected off a surface, the eyes pointing to different directions can experience different vertical illuminance.  
Circadian Light Meter app

Different workstations inside the office premises may experience different circadian entrainment, especially for those sitting inside a cubicle. In order to facilitate its assessment at a specific position of the office worker, an Android app called "Circadian Light Meter" has been developed for free download. Its download link is at Google Play Store.
  This app makes use of the light sensor and accelerometer of the Android phone to determine the vertical illuminance, after the user aligns vertically his/her cell phone near the eyes. Then the circadian entrainment is calculated according to two different metrics, namely, Equivalent Melanopic Lux and Circadian Stimulus. Also the blue light content is displayed , together with the mix percentage of blue-turquoise light and blue-violet light.  
  Supplemental lighting if required

LiteBlue Desk Lamp provides additional blue-turquoise enriched cool-white color light (5000K CCT) to remedy the ambient lighting environment during daytime, if required. During nighttime, warm-white color light (3000K CCT) helps Melatonin secretion for a good night's sleep.

1 Three selectable light levels: Low, Medium, High
2 Two selectable color temperatures (5000K cool white and 3000K warm white)
3 Adjustable arms of 33 inches (84 cm) maximum height above desk, and allowing the light to fall from top to bottom and at an angle to the eyes
4 Rotating lamp head at different angles for eye comfort
