Q: What is the lifespan of LEDs?
A: Long lifespan stands out as the number one benefit of LED lighting. LED bulbs and diodes have an outstanding operational lifespan of up to 100,000 hours, which is 11 years of continuous operation or 22 years of 50% operation. Imagine not having to replace a bulb/fixture for over 20 years!
LED’s differ from standard lighting in that they don’t burn out and stop working, but rather gradually reduce their light output over a long period of time. The rated lifespan of LED’s is when the light output has reduced to 70% of the initial output which is called the L70.
Q: How much will it cost to install a new system? How much money will really be saved? How long will it take for the business to recoup its initial investment?
A: Accurately estimating a return on investment for an LED lighting upgrade requires gathering key information.
- The current number of lamps
- The wattage of the current lamps
- How many hours a day lamps will be on
- How many days of the week lamps will be on
- The current kilowatt hour rate
- The yearly cost of maintaining the current lighting system
A: Led lights are free of toxic chemicals. Most conventional fluorescent lighting bulbs contain a multitude of toxic materials, e.g., mercury, that are dangerous to the environment.
LED lights contain no toxic material, are 100% recyclable and will help you reduce your carbon footprint by up to a third. The long operational lifespan mentioned above means that one LED light bulb will replace the material and production of 25 incandescent light bulbs, a big step towards a greener future!
Q: Why are LED lights more energy efficient?
A: LED lighting is today’s most efficient way of illumination with an estimated energy efficiency of 80-90%. This means that about 80% of the electrical energy is converted to light and about 20% of the energy is lost to heat and other energy forms. Compare this to traditional incandescent lighting which operate at only 20% efficiency and the difference is astounding!
Q: How do LEDs help with my maintenance cost?
A: The long lifetime of LEDs reduces the need to replace failed lamps, and this can lead to significant savings, particularly in the cost of sending out maintenance crews. This also makes LED fixtures useful for installation in relatively inaccessible locations.
Maintenance savings stem from the following
- Cost of time to report light outage
- Cost of material for repairing non functional lights
- Labor costs for the replacement of bulbs / ballast /striker etc.
Q: Why/how do LEDs produce almost no radiated heat?
A: LEDs don’t produce heat in the form of infrared radiation, which makes incandescent bulbs hot to the touch. The absence of IR radiation allows LED fixtures to be positioned in locations where heating from conventional sources would cause a particular problem, e.g. illuminating, food or textiles.
