Building biologist measures lightquality of a computer screen
Building biologist Jens Rudloff (Germany) regularly measures the light quality of his computer screen with a professional measuring device. The “Eco-Mode” of the LED monitor from Fujitsu has a brightness level of 55. For comparison, Rudloff sets the brightness level to 95 and measures whether there are any differences in terms of flicker or blue light for the user. In addition to the light from the ceiling light, the building biologist adds a bright halogen desk lamp during the experiment. As usual in building biology, he uses natural sunlight as a guideline.
