Fluorescent bulbs and light-emitting diodes (LEDs) have taken over lighting because they are more energy efficient and can provide better lighting than incandescent bulbs.
Do LED lights keep you awake?
The consensus seems to be that avoiding LEDs, either in the form of actual light bulbs or LED powered screens at least an hour before we go to sleep can help us fall asleep faster and sleep better.
