Question:
What causes fluctuations in a light source?


Replies:
This is a very general question. Do you have a specific fluctuation in mind?

The most significant variation would be due to voltage variations. For example, a fluorescent light generates light that fluctuates at 120 Hz (60 Hz supply voltage). It varies from maximum intensity to nearly off twice during each cycle. Dr.
