Incandescent Bulbs: The Hidden Disaster You’re Still Using Every Night For decades, incandescent bulbs have been the default choice for home lighting. With their warm glow and familiar design, they’ve decorated living rooms, bedrooms, and offices countless times. But beneath their simple charm lies a cautionary truth: incandescent lighting may be out of step with a more sustainable, efficient future. If you’re still relying on old incandescent bulbs every night, you might be unknowingly contributing to energy waste and higher utility costs—without even realizing it. ### What Are Incandescent Bulbs? Incandescent bulbs produce light by heating a thin tungsten filament until it glows. While this method delivers a familiar, consistent light, it’s incredibly inefficient. A staggering 90% of the energy consumed by incandescent bulbs is converted into heat—not visible light. Only about 10% is actually usable as illumination. This inefficiency makes them far less practical in today’s energy-conscious world.
