Just installed a 15,000 lumen dusk to dawn LED area light in Michigan and it flashes off and on when the temp drops below 40 degrees. If I bring it in the house for a while it works just fine. Any idea which component is the culprit? The output is amazing but it's useless right now. Was thinking of bypassing the photo sensor to see if that's the problem. It has a non-replaceable photo sensor.

This sounds like a cold solder joint to me. Get yourself a can of freeze spray, let the light warm up indoors and then start spot-chilling areas of the circuit board until you get it to fail. Then get a magnifier and a bright light and look for a failed solder joint.
It's this one. I'm gonna swap it out for the same one and see what happens but I'm guessing it'll do the same thing. Gonna grab the 10,000 lumen model also just in case.

Debugging can be challenging but being brand new and malfunctioning I would think about returning it.
You may well find the defective part but it may or may not be easily obtainable/replaceable.
Working on line-powered stuff has implications for insurance, should anything go wrong.
Not raining on anyone's parade, as I like debugging/repairing things, just mostly low-voltage.

+1 to Photon wrangler. Sound like a cold joint somewhere. Most likely in the power supply but no guarantee. The power supply could be just faulty or poor design.
