LED lights are one of the most energy-efficient lighting options on the market today, and they outperform incandescent and CFLS lighting in almost every area. The LED energy savings that you can expect make them well worth the investment.
LED energy savings
LEDs are among the most efficient lighting technology on the market today. This has the potential to have a huge impact on energy savings in the United States. LED light bulbs made for residential use, especially with an ENERGY STAR rating, use at least 75% less energy and last 25 times longer than incandescent lighting.
According to the Energy.gov, if LED light reaches widespread usage by 2027, we could see energy savings of about 348 TWh of electricity. That is roughly the equivalent of the annual electrical output of 44 large electric power plants. It would also save more than $30 billion at today’s energy prices.
How LEDs are different
Obviously to get those kind of LED energy savings, LED bulbs are significantly different than their incandescent and CFLS counterparts. Some of their primary differences include:
- Light source: LEDs are very small, about the size of a fleck of pepper. A mixture of red, green and blue LEDs is used to make white light.
- Direction: Traditional lights require a reflector to direct the light being emitted. LEDs only emit light in a specific direction and don’t require a reflector. With traditional lighting, more than half the light never leaves the fixture.
- Heat: LED lights release very little heat during usage. Incandescent bulbs, on the other hand, release 90% of their energy as heat and CFLS release about 80% of their energy as heat.
