THD and PF of Selador Series?

What is the worst-case THD of the Seldor Series across its dimming range?

What is the worst-case PF across its dimming range?

Thanks!

    I just ran a quick test here. THD and PF are worst when the fixture is at 0%.

    These tests were performed at 120V 60Hz on a single cell Vivid fixture.

    Level Current Draw (A, RMS) Total Harmonic Distortion, Current (ITHD, %) Power Factor
    All Colours OFF 0.17A 35% 0.83
    All Colours @ 25% 0.26A 30% 0.89
    All Colours @ 50% 0.41A 20% 0.96
    All Colours @ FULL 1.06A 11% 0.98

    Let me know if that helps, or if we can provide any further information to help.

    Regards,
