The rise of LED lightbulbs has been driven in large part by their environmental credentials, and rightly so. LEDs consume a fraction of the power used by traditional incandescent bulbs and have exceptional longevity, lasting up to 25,000 hours.

Most of an LED’s environmental impact (around 98 percent) is incurred during its use. Factors such as longevity and efficiency present the greatest opportunity for LED manufacturers to improve the environmental impact of their products. After that, the biggest influencing factor — the “greenness” of the power source itself — is out of manufacturers’ hands.

One notable area where manufacturers can drive significant eco-improvements is in their selection of substrate, a choice that can allow for improvements at both ends of the product’s lifecycle.
