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 (I_THD, %)	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,

Tom

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.
