I'm troubleshooting some UFO high Bay lights in a shop. There are 6 lights. They're rated AC85 -277V. They're plugged into a 120v outlets in the ceiling.
They're flickering in unison.
When I unplug one light at the outlet box that powers the rest of the lighting plugs down the line, and plug in another exact same type of light into the outlet, they all stop flickering.
When I disconnect that light from the outlet, they all start flickering again.
I'd like to understand why this is happening.
Voltage to the 1st outlet box is fine and steady. All connections are tight.
The lights are 300 watt each on a 20 amp circuit.
Here's a link to a short video showing what I'm talking about -
Thanks!
