LED Frequently Asked Questions
What does LED stand for and what are they?
Light Emitting Diodes, regularly called LEDs, are genuine unsung heroes in the today’s world. They do many distinctive jobs and are found in all different types of gadgets. In addition to everything else, they form numbers on digital clocks, transmit data from remote controls, light up watches and let you know when your devices are turned on. Grouped together, they can form pictures on a large flat TV screen or light up an entire area while replacing old fashioned filament lights.
Essentially, LEDs are simply small lights that fit effortlessly into an electrical circuit. However, unlike common incandescent bulbs, they don’t have a filament that will wear out and they don’t get particularly hot. They are lit up only by the movement of electrons in a semiconductor material, and they keep going as long as a standard transistor. The lifespan of a LED surpasses the short life of a incandescent bulb by thousands of hours.
Why is LED Lighting the next generation of lighting?
LED lights are the next generation of lighting that save energy, reduce maintenance and replacement costs and help protect the environment. They also last much longer than traditional lighting.
What type of light quality can I expect with LED lights?
LED lights can match your existing lighting in terms of brightness and color. But, as with any product, there can be poor quality and high quality LED lights. You may have had experience with poor quality products already that do not match your existing lighting. Encore LED will help you select the correct fixture to replace your existing lighting in terms of brightness and color temperature.
How energy-efficient are LED lights?
LED lighting can save up to 90% of the electricity used by incandescent and halogen lights and up to 50% of electricity used by fluorescent lights.
Where are LED lights being used?
LED lights are being used where the lighting is on for a long time such as hotels, restaurants, shops, factories, auto dealerships and outdoor lighting.
Is LED lighting better than incandescent or halogen lighting?
Around 80-90% of the energy emitted from incandescent bulbs is converted to heat instead of light. LED lighting is about 85% more efficient than incandescent lights and hence do not need as much energy to product the same amount of light. LED lights are also designed to last about 50 times longer than incandescent lighting.
What is the best choice: LED, fluorescent or CFL?
Unlike LED lights, most fluorescent lights and compact fluorescent lights (CFLs) harbor hazardous materials, such as mercury. This requires their careful and proper disposal, ensuring that they do not contaminate landfill sites. As most cannot be dimmed, Fluorescent lights may suffer from flickering. Unfortunately, people can be sensitive to this effect – resulting in eye-strain, migraines and other head-aches. LED lights, like those from Encore LED, utilize solid-state technology enabling stable dimming with no flickering. Fluorescent lights may take noticeable time to reach optimum brightness, a problem that is compounded in cold conditions. LED lights are instant-on in any environment – even inside cold rooms and freezers.
How long can LED lights last?
Good quality LED lights can have a lifetime of 50,000 hours or more but the average is around 35,000 hours. But this all depends on their design and how they dissipate heat from the LED chip. Depending on how many hours they are used a day, Encore LED lights can last as long as 20 years. Unlike other lighting products LED lights do not completely fail – they get dimmer. At 50,000 hours of use (or their rated lifetime), an LED light will be designed to provide at least 70% of its initial light output (LOR). The lifetime is dependent on many different factors including fixture design, LED chip type, ambient temperatures and fixture design. Actual life of an LED is complicated to calculate and should be based on LM-80 measurements (calculated by independent testing labs) of the LED sources. Well-designed LSI Industriees LED lights get the optimum balance between light output and longevity.
Aren’t LED lights too expensive?
The upfront cost of LED lights is higher than conventional lights but they save a lot of money over time from reduced energy usage, low replacement and maintenance costs. But how do you define expensive? Is it the up-front cost or is it the running cost of the light over time or the cost to change the light once it has failed? If it is a new building, installing LED lighting is sometimes the same cost as traditional technology which means you will start to save from the very beginning.
Can LED lighting really save energy and money?
Figures released by the U.S Department of Energy estimate that embracing LED lighting on a large-scale by 2025 will:
- See a 62% reduction in energy usage.
- Result in 258 million metric tons of carbon emissions wiped out.
- Greatly reduce the amount of materials being put into landfills
- Mean no need to build 133 new power plants.
- Overall it would save the US over $280 billion!
The Energy Independence and Security Act of 2007 is designed to implement sweeping changes to energy policies in the United States. The stated mission of the act is “to move the United States toward greater energy independence and security, to increase the production of clean renewable fuels, to protect consumers, to increase the efficiency of products, buildings, and vehicles, to promote research on and deploy greenhouse gas capture and storage options, and to improve the energy performance of the Federal Government, and for other purposes.” Section 321 of this act addresses new efficiency standards regarding “general service incandescent lights.”
Encore LED strongly recommends that business, industrial and commercial lighting consumers choose to proactively adjust their lighting purchases in order to start saving on energy costs now.
