Flash light Meausrement
Measurement of hand-held/portable flashlights, spotlights, and headlamps providing lighting.
The root cause of FlickerThe source of this problem is the power current, particularly a conflict with the mains (from the outlet) and the power supply (of the light). Dimmers also induce or increase flicker. All lights running on AC power have this problem to a certain degree. Fluorescent lights had long been most criticized for high flicker before more recent advances.
LED has Flicker ProblemNow LEDs are also beginning to exhibit the same symptoms. LEDs further complicate the issue with their changing power needs that come with temperature fluctuations. LEDs should be equipped with what is called an LED driver. It sits between the power supply of the light and the light itself. It's main function is to regulate or maintain a constant voltage to the LED - a well designed driver will adequately mitigate the problems of flicker. If an LED is equipped with components for other types of lights (e.g. transformers), this will also cause flicker problems.
