The light-emitting diode (LED) is one of today’s most energy-efficient and rapidly-developing lighting technologies. Quality LED light bulbs last longer, are more durable, and offer comparable or better light quality than other types of lighting.
HOW LONG DO LEDS FOR GENERAL LIGHTING REALLY LAST?
LEDs are Solid State devices (SSL or “solid state lighting”); so they will not burn out. Life expectancy for SSL lighting is upwards of 50,000 to 100,000 hours or more, which means no maintenance costs for facilities workers to replace lights. Over time, the cost of replacements for fluorescent or incandescent bulbs themselves can add up to a significant savings when converting to LEDs.
LED lights are typically rated to last about 100,000 hours. An incandescent light bulb is rated for about 1000 hours. CFLs or Fluorescent Tube lights are rated for 6-8000 hours. The product replacement cost math is easy:
Type of Light Bulb – Life Hours – Replacement Cost
LED Lighting – 100,000hrs (10yrs) – 1 x Buy Once
Fluorescent / CFLs – 6-8000hrs – 13 x $4ea = $52
Incandescent Bulb – 1000hrs – 100 x $1ea = $100
DO LED LIGHT BULBS CONTAIN MERCURY?
No. LED bulbs do not contain mercury and do not need to be recycled. They are manufactured without any hazardous materials unlike fluorescent or HID bulbs.
HOW DO LED LIGHT BULBS COMPARE TO CFL BULBS?
Studies show LED light bulbs use 50% less energy than CFL bulbs and in many cases last 10 times longer than CFL light bulbs. They are much more durable, environmentally friendly, vibration and shock resistant, and offer excellent light quality – both indoor and outdoor.
HOW ARE LEDS ARE DIFFERENT?
LED lighting is very different from other lighting sources such as incandescent bulbs and CFLs. Key differences include the following:
Light Source: LEDs are the size of a fleck of pepper, and a mix of red, green, and blue LEDs is typically used to make white light.
Direction: LEDs emit light in a specific direction, reducing the need for reflectors and diffusers that can trap light. This feature makes LEDs more efficient for many uses such as recessed downlights and task lighting. With other types of lighting, the light must be reflected to the desired direction and more than half of the light may never leave the fixture.
Heat: LEDs emit very little heat. In comparison, incandescent bulbs release 90% of their energy as heat and CFLs release about 80% of their energy as heat.
HOW DO LEDs SAVE 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 25 times longer, than incandescent lighting.
Widespread use of LED lighting has the greatest potential impact on energy savings in the United States. By 2027, widespread use of LEDs could save about 348 TWh (compared to no LED use) of electricity: This is the equivalent annual electrical output of 44 large electric power plants (1000 megawatts each), and a total savings of more than $30 billion at today’s electricity prices.
As a rule, LED bulbs use 90% less electricity than standard bulbs. They have an unparalleled even spectrum of light and have a lifespan beyond ten years. LED’s provide us the most efficient way to save energy and conserve our natural resources.
If LED’s were implemented right now universally, we would not need to build another power plant. LEDs would actually eliminate the need for over 30 existing power plants!
