Hey everyone, the secret about LED lighting is out!
A once highly technical and expensive way to save energy, now-a-days almost everyone has at least one LED light bulb screwed into a fixture at their home. Why? That’s the topic of this week’s Remke blog post.
How LED Lighting Changes the Way Your Home Consumes Energy
A light-emitting diode (LED) is one of today’s most energy efficient and rapidly developing lighting technologies available. They produce more lumens per watt, meaning less power is needed to produce more light bringing you more energy savings! LED bulbs last longer, are more durable and offer comparable or better light quality than other types of more traditional lighting.
What is an LED?
Energy Star describes LED lighting as “directional” light sources. Which means they emit light in a specific direction, unlike incandescent and CFL, which emit light and heat in all directions. That means LEDs are able to use light and energy more efficiently than many of their counterparts.
Become bright almost immediately.
According to Energy Star, LED light bulbs produce light when electrical currents pass through them. With CFL bulbs, an electric current flows between electrodes at each end of a gas-filled tube. The reaction creates ultraviolet light, which is then changed into light when it hits a phosphor coating on the interior of the bulb. This process takes anywhere from 30 seconds to 3 minutes to complete, which is why it can seem as if your CFL light takes a while to become fully lit. With LEDs on the other hand, you get instant full light in no time.
Use less wattage.
A typical 84-watt fluorescent can be replaced by a 36-watt LED providing the same level of illumination. Less energy use reduces the demand from power plants and decreases greenhouse gas emissions.
Last longer than any fluorescent bulb available (up to 10 years in a new fixture!).
Have no mercury content leading to a reduction in toxic chemicals deposited into our landfills. Incandescent bulbs release 90% of their energy as heat and CFLs release about 80%. LEDs emit very little heat and run significantly cooler, helping to reduce the energy used in lighting and cooling.
According to the US Department of Energy, widespread use of LED lighting has the greatest potential impact on energy savings in our country. By 2027, the use of LEDs could save about 348 TWh (terawatt-hours) when compared to no LED use at all.
These savings are equivalent to the annual electrical output of 44 large electric power plants and represent a total savings of more than $30 billion! It’s fascinating that one small change, like replacing a light bulb, could have such a major impact on our environment and utility bill.
LED lighting is currently available in a wide variety of home and industrial products, and the list is growing every year. From table lamps, to outdoor floodlights, to Christmas lights, the rapid development of LED technology leads to more products and improved manufacturing efficiency. This results in lower prices for everyone!
Within a residential living space, LEDs are commonly used in the kitchen as under-cabinet lighting. Since they are small and directional, these lights are ideal for cooking and task lighting. LEDs are also commonly found within recessed downlights in kitchens, hallways, bathrooms, and office/commercial spaces.
