@EmptyBadger … below is a post with I think the last 2-3 years reaults.
I changed from mini incadescent Christmas lights to C9 incadescent bulbs this last year and they worked fine.
My lows here the past 3 winters were 3F (2023), 2F (2024), 12F (2025).
In 2022… i tried it but did not have the incadescent lights and and my greens died mid January.
With the lights… have successfully grown greens all winter the past 3 winters.
