What is an LED?
LED is the common abbreviation for a light-emitting diode. An Light emitting diode is made up on a diode that makes light when electricity is passed throught it. The electronics industry has used Light emitting diode technology for several decades as indicator lights for various electronic devices . In more recent years, LED technology has progressed to the point where it is viable for general lighting applications .
What are the advantages to using Light emitting diode lights?
LEDs has several advantages – 50,000 hour lifespan, uses between 50% – 90% less electrical energy than other bulbs, extremely durable and requires less maintenance. This translates into energy savings, upkeep financial savings and an overall decrease in cost of ownership over the product’s lifetime .
What’s the difference between performance and efficacy?
Efficacy is a term normally used in cases where the input and output units differ. In lighting, we are concerned with the amount of light (in lumens) produced by a certain amount of electricity (in watts).
On the other hand, efficiency is a term that is typically dimensionless. For example, lighting fixture performance is the ratio of the total lumens exiting the fixture to the total lumens initially produced by the light source.
Do I have to replace LED diodes?
Light emitting diode Lights never dies out like an ordinary bulb, the individual diodes do not have to be replacesd. LED lights produce less light as they age, Light emitting diode lights will lose around 30% of their output over 50,000 hours. If one LED fails, it does not require a complete fixture outage.
Why is the lifespan of an Light emitting diode measured as lumen depreciation?
The lifetime of an Light emitting diode is vastly longer than that of incandescent, fluorescent or HID lamp sources, generally lasting 50,000 hours or longer. Although the Light emitting diode never really burns out, product lifetime is measured by lumen depreciation.
How efficient are led bulbs compared to incandescent bulbs?
LED lights use 90% less energy than incandescent bulbs, also incandescents only last around 1000 hours whereas LED lights should easily last around 50,000 hours. The newest generation of LED’s are eight to ten times as efficient as incandescent bulbs.
What happens when the bulb burns out?
Light emitting diode’s do not burn out like typical light fixtures – they gradually degrade over time. Quality LED Lights should retain approximately 70% of their output for their first 50,000 Hours of operation.
What is the difference between Cool White and Warm White?
Warm White is a similar light output to that of a incandescent light bulb. Cool White is more like the color of white that is produced by fluorescent lights. It is 25% brighter than Warm White and is better for applications that require increased illumination or more energy efficient projects .
What about the High Cost?
The primary limitation is the current high cost of Light emitting diode light bulbs. Even though the cost of LED lights is steadily decreasing, startup cost may seem daunting, but LED light bulbs pay for themselves over time since they can last for up to 11 years, and saves a lot of money in terms of electricity used.
For businesses, using Light emitting diode lights makes a whole lot of sense since the reduced upkeep costs more than make up for the steep start-up costs.
