Lighting is changing very quickly. Most understand the technology change, but few understand how light affects human physiology. Advancements in technology have enabled us to design lighting for human performance. EPL’s mantra is “get lighting right for the occupant of the space and the energy savings will naturally fall into place”.
Step back and think about evolution, all life began with light. We spent a million years getting up with the sun and going to bed with the sun. Only in the last hundred years has that really changed. Below is a spectrum of natural daylight and light under a fluorescent lamp. The difference in spectrums is obvious.
