Since then, LED light bulbs and light fixtures have drastically improved the energy efficiency of how we light our homes and buildings. According to the United States Department of Energy, "LED is a highly energy-efficient lighting technology and has the potential to fundamentally change the future of lighting in the United States. Residential LEDs -- especially ENERGY STAR rated products -- use at least 75% less energy, and last up to 25 times longer, than incandescent lighting."

The rapid growth of LED lighting products greatly impacts the total energy consumed by lighting. Department of Energy statistics reports that demand for electricity for lighting dropped to around 13 percent of total energy consumption in . At current LED growth and expansion rates, this figure should drop to 8 percent of total energy consumption by .
Despite the significant energy efficiency gains in lighting technology, there is still room for improvement. Almost three-quarters of households (71 percent) still have at least one incandescent bulb. In the United States, around 11 percent of households use only incandescent lights for exterior and interior illumination.
According to the Rapid Transition Alliance, a network of international organizations that are engaged in practical work, research, and campaigning to tackle the climate emergency:
As we mentioned in the introduction, CFL bulbs were the first energy-efficient bulbs to hit the market and were generally between 5 and 7 times more efficient than traditional incandescent bulbs. Today, LED lighting fixtures for general illumination in and around the home are the most energy-efficient and rapidly-developing lighting technology. LEDs use up to 90 percent less energy and last up to 25 times longer than traditional incandescent bulbs. Although once known mainly for indicator and traffic lights, LEDs in white light and general illumination applications are today's most energy-efficient and rapidly-developing lighting technology. LEDs use up to 90% less energy and last up to 25 times longer than traditional incandescent bulbs.
Unlike some energy-efficient appliances, electronics, and other home upgrades, LED lighting fixtures have fast "pay-back periods." Given this reality, switching to LED energy-efficient light fixtures offers a win-win scenario. Not only can homeowners drastically reduce their electricity from their home lighting needs, but they will also begin to save money immediately.
These fixtures incorporate the latest technology to distribute light more efficiently and effectively. Another benefit of ENERGY STAR-certified light fixtures is that homeowners can find hundreds of styles and uses. From table and floor lamps to hard-wired lighting fixtures for your porch, ceiling, wall, bathroom vanity fixtures, and more, homeowners today can find ENERGY STAR lighting fixtures for virtually every lighting need they may have.
Furthermore, ENERGY STAR-certified models last 15 times longer than similar incandescent options and have a manufacturer-back warranty of at least three years.
How Using Efficient Lighting Benefits Your Business
If your building relies on inefficient lighting, such as incandescent, halogen, HID, or T12 fluorescent, you’re missing out on significant savings. Updating your lighting can be a great first step when it comes to making your building an efficient one. Lighting makes up 17% of all electricity consumed in U.S. commercial buildings, meaning there’s plenty of opportunities to make your lighting more energy efficient.
The Perks of LED Lighting
With LED lighting, you can greatly reduce the electricity used by your commercial building with many light fixtures available to meet a wide variety of needs and applications. There are countless opportunities to make the switch to LED, including streetlights, parking garage lighting, and task lighting.

Upgrading to LEDs can improve your business and performance. LEDs:
- Provide the same brightness as traditional bulbs but use 90% less energy
- Last 15 times longer, which means big financial savings on operations and maintenance.
- Produce very little heat compared to incandescent bulbs, which release 90% of their energy as heat, and CFLs, which release 80% of their energy as heat
LEDs also pack a serious punch for the environment. By , widespread use of LEDs could reduce our nation’s electricity use equal to the annual electrical output of 44 large electric power plants, and lead to total savings of more than $30 billion.
Is it the Right Time to Upgrade?
It’s never a bad time to improve your commercial building’s energy efficiency, and LEDs make financial sense in most scenarios. Buildings in regions with high electricity costs and buildings with long operating hours will achieve the greatest return on investment. Here’s how your business can benefit:
- Reduce operating expenses
- Increase your company’s commitment to energy efficiency
- Take advantage of utility rebates
LED Utility Rebates and Incentives
Utilities and other energy efficiency program sponsors offer incentives (e.g., mail-in rebates, buy-downs, and instant rebates) throughout the United States to promote ENERGY STAR certified bulbs and fixtures, decorative light strings, and ceiling and ventilating fans with light kits. Many of these programs specifically target commercial buildings and reach up to $249 in savings for LED light fixtures.
