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.

Tom
Thank you!
I just made a quick edit to these. My original readings were made with a current clamp that wasn't quite sensitive enough. Just repeated it with better measurement tools - so now more accurate.
