LED lights have been used for a lot of things from TVs, computer monitors, new lighting systems and scrolling LED signs. However, no matter how much it is used in the industry nowadays, many people still have the wrong ideas about LED lights. So for today’s article, we’re going to debunk some of these false facts regarding LEDs.
LED lights can indeed last longer compare to other traditional lights including CFL, incandescent and fluorescent but they don't last forever. Like all light sources, LED sources slowly fade over time. But as stated earlier, LED can last over a period of 6,000 hours or more. Well-designed LED lighting fixtures can retain 70% of their initial output for 50,000 hours or more, depending on operating conditions and other factors.
Because LED produces no infrared energy, the beam of light from an LED source is cool. However, waste heat is produced within the LED itself during the conversion of electricity into light. LEDs don’t give off radiant heat, but they do need to get rid of conductive heat in order to achieve long life.
LEDs are really expensive but are getting cheaper at an impressive rate through the years. Although incandescent lights cost less than LED lights, LEDs last longer than them. Weighing cost and light quality, LEDs are worth considering. They are quality-wise and put out enough light for a lot of needs. Home Depot's 800 lumen Philips LED bulbs are priced at just under $40 and consume 12 watts. A 40-watt equivalent from Lighting Sciences Group, which consumes less than 8 watts, costs just under $18.
If you compare light output of other lightings to LED, it may seems that LED delivers less light but such comparison is inaccurate and misleading. Conventional lighting waste more light unlike LED lights. LED performs as well than other lightings, and sometimes even better, while consuming far less energy.
Another myth says that LED lights can only produce blue light, when in reality white-light LEDs can produce very nice color temperatures ranging from 2,700K to 6,500K. LEDs have a unique ability to control light to very specific spectra.
LEDs are about 15 percent more efficient than fluorescent lights, and six times as efficient as incandescent. "Well-designed LED lighting can retain 70% of their initial output for 50,000 hours or more, depending on operating conditions and other factors," according to LEDLightingExplained.com.
• Myth #1: LED lights can last forever.
LED lights can indeed last longer compare to other traditional lights including CFL, incandescent and fluorescent but they don't last forever.

Well-designed LED lighting fixtures can retain 70% of their initial output for 50,000 hours or more, depending on operating conditions and other factors.
• Myth #2: LEDs don’t give off any heat.
Because LED produces no infrared energy, the beam of light from an LED source is cool. However, waste heat is produced within the LED itself during the conversion of electricity into light. LEDs don’t give off radiant heat, but they do need to get rid of conductive heat in order to achieve long life.
• Myth #3: LED systems cost too much.
LEDs are really expensive but are getting cheaper at an impressive rate through the years. Although incandescent lights cost less than LED lights, LEDs last longer than them. Weighing cost and light quality, LEDs are worth considering. They are quality-wise and put out enough light for a lot of needs. Home Depot's 800 lumen Philips LED bulbs are priced at just under $40 and consume 12 watts. A 40-watt equivalent from Lighting Sciences Group, which consumes less than 8 watts, costs just under $18.
• Myth #4: LEDs are not bright enough or can only produce blue light.
If you compare light output of other lightings to LED, it may seems that LED delivers less light but such comparison is inaccurate and misleading. Conventional lighting waste more light unlike LED lights. LED performs as well than other lightings, and sometimes even better, while consuming far less energy.
Another myth says that LED lights can only produce blue light, when in reality white-light LEDs can produce very nice color temperatures ranging from 2,700K to 6,500K. LEDs have a unique ability to control light to very specific spectra.
• Myth #5: LED light quality is poor.
LEDs are about 15 percent more efficient than fluorescent lights, and six times as efficient as incandescent. "Well-designed LED lighting can retain 70% of their initial output for 50,000 hours or more, depending on operating conditions and other factors," according to LEDLightingExplained.com.
