Turning on the lights early isn’t because it’s already completely dark, but rather stems from a sophisticated survival strategy—managing the “visual transition period.” This is not merely a habit, but a science concerning safety and circadian rhythms.

LEDs generate almost no heat, which is an advantage in the summer but a fatal flaw in the winter. In extremely cold environments, thermal management for lighting is no longer just a matter of heat dissipation; it becomes a matter of survival—affecting both battery life and the lifespan of the equipment.
