Neon signs boast energy efficiency due to their low power consumption and extended lifespan. They require minimal electrical energy to produce their iconic illumination. Their gas-based illumination, using inert gases like neon or argon, is highly efficient, requiring minimal power to generate light. This stands in contrast to traditional incandescent or fluorescent lighting. Neon signs, often incorporating cold cathode technology, maintain a consistent, energy-saving glow, making them an environmentally friendly and cost-efficient choice for striking signage.
