What is the worst-case THD of the Seldor Series across its dimming range?
What is the worst-case PF across its dimming range?
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.
Let me know if that helps, or if we can provide any further information to help.
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.
