Best way to reduce supplemental lighting this winter?

[Dimples]

In addition to the other great suggestions, if you don’t want to ditch the lights completely for the phals, you could consider running the lights only during the darkest two months of the winter.

Hypothetically, if you usually run the lights for 4 months out of the year, running them as you normally would for two months would reduce your usage by 50% but still provide a lot of light when you are providing light.
