LEDs and the Sustainability Revolution
Over the last decade, LED lighting has paved the way for the sustainability revolution, particularly in the manufacturing industry.
Sure, the shift to an energy-efficient reality may seem more subtle than industry-wide policy changes or a shift in sustainability laws. It’s not an overnight change, but rather a series of upgrades made by individual businesses over time. The results, however, are not subtle in the slightest. No, the impact these lighting implementations have had is significant on the environment, economy, and operations.
Energy Efficiency Powers Sustainability
One of the most immediate benefits of LED lighting is its exceptional energy efficiency. LEDs use up to 75% less energy than traditional lights. For manufacturers, this directly translates to lower electricity bills. Arguably more importantly though, the reduced energy consumption cuts greenhouse gas emissions.
In the last 10 years, manufacturing facilities have reported a massive reduction in CO₂ output thanks to these lighting upgrades. The U.S. Department of Energy predicts that the widespread use of LED lighting in industrial and commercial buildings could save more than 569 terawatt-hours annually by 2035. If you’re having a hard time picturing that quantity, try this: It is the equivalent to the annual output of more than 92 large power points.
Long Lifespan, Less Waste
50,000 hours or more. That’s how long LEDs can last, significantly outliving traditional lighting. Longevity is key in the manufacturing sector, as it minimizes disruptions caused by maintenance. In facilities that operate all day and night, seven days a week, unnecessary maintenance cycles wastes money and operational efficiency.
Less frequent replacements = fewer materials needed = fewer bulbs shipped = fewer bulbs disposed of = a greener supply chain in the lighting industry itself.
Heat Output Not What It Used To Be
An unexpected benefit from the rise of LEDs has been the heat output reduction. When so many facilities are seeing less heat output in their lighting, the world is seeing greater environmental benefits. This is because in many facilities, climate control is crucial for the effectiveness of their products. HVAC systems run overtime to compensate for over-heated lights, a process that isn’t necessary if there’s no extra heat to be accounted for. The environmental impacts may be indirect, but they’re extremely valuable.
Smart Lighting: The Smarter Choice
An absolute superhero of the manufacturing industry (and lighting industry itself) has been occupancy sensors. A massive amount of energy is wasted by using light when we don’t actually need it. Other lighting systems can be automated based on daylight availability or production schedules. Unnecessary energy usage contributes to completing manufacturing goals.
Final Thoughts
LED lighting may not grab headlines, but it sure is worthy of doing so. Its impact over the last decade is undeniable, especially in energy-hungry environments like manufacturing. In other words, LEDs have proven to be a small switch, with a big return. They’re not just a tool; they’re a foundational piece of a more environmentally responsible future.
