Researchers affiliated with Ben-Gurion University of the Negev and the Weizmann Institute of Science report that hackers can now eavesdrop on individuals from 80 feet away or more, using a standard lightbulb.Granted, there are compounding factors at play, such as whether or not any curtains or lampshades interfere with the visibility of the lightbulb. Additionally, the thickness of the glass, and the output of the light can affect eavesdropping success rates.

Since this is in off-topic 🙂

it is just an extension of the old spy-craft method to use a window pane as a microphone. To make it reliable, you need to use a laser. Here the guys are using internal room light source, but the main idea is still the same.
