[CC] LED Lights- their Power Factor & Harmonics

Hi guys! In this video I tested power, power factor, and harmonics distortion of some LED lights that I bought from a mall hardware store. I used the Hioki CM3286-01 AC Clamp Power Meter. To visualize these parameters, I connected the device to my smartphone through Bluetooth® using the Hioki GENNECT CROSS App which is available from Google PlayStore and Apple App Store. Note that this was an electrical test. It did not include testing the lamps’ illumination or brightness. Stay safe & thanks for your support!

    Hello Master.
    What is the difference between THD-F and THD-R ?
    Thank you very much for this video.

    could that clamp be used at the main distribution board to measure the overall power factor of the whole circuit with different appliances running
