Photometric Flicker is a process that light changes quickly and periodically over time. Lots of artificial light sources exist photometric flicker, such as traditional fluorescent lamp and dimmable LED. Unfortunately, more and more researches show that flicker threaten people’s life and heathy.

  For this reason, we researched specifically for flicker test, and developed a full-automatic flicker measurement and assessment instrument —— FP2000 Instantaneous Transient Digital Photometer and Flicker software.
