While the actual manufacture of light bulbs hasn’t changed much since Edison’s day, one significant change is afoot: new, energy-efficient LEDs are poised to take over the market.
Unless you’ve had to replace all of your light bulbs at the same time (for your sake, we hope not!) you might not be aware of this astonishing fact: the average home contains more than 40 light bulb sockets. Indeed, lighting alone accounts for 25% of the average household’s energy bill.
To meet all of your lighting needs, manufacturers sell approximately 2.5 billion light bulbs every year, generating around $1.2 billion in revenue. As households look to become more energy-efficient, however, LED bulbs are becoming increasingly popular, gradually replacing traditional incandescent bulbs as the world’s preferred source of light. As the LED revolution continues to transform the industry, let’s take a closer look at light bulb manufacturing, the industry’s supply chain, and the future of lighting.
