What are the advantages to using Light emitting diode lights?
LEDs has several advantages - high efficiency and durability, much longer lifespans, reduced upkeep . These advantages makes LED lights a much easier and cheaper option to run over the course of its lifespan.
What's the difference between performance and efficacy?
Efficacy is a term normally used in cases where the input and output units differ. In illumination, we are concerned with the amount of light (in lumens) produced by a certain amount of electrical energy (in watts).
On the other hand, performance is a term that is typically dimensionless. For example, lighting fixture efficiency 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 Light emitting diode 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, LED 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 LED 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 LED never really burns out, product lifespan 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 Light emitting diode lights should easily last around 50,000 hours. The newest generation of Light emitting diode'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 Light emitting diode 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 the light colour an incandescent light bulb makes - it is labelled warm as it has a slightly more "yellow" colour whereas cool white is pure white and extremely bright - if you think of a fluorescent tube this light colour will be close to cool white.
What about the High Cost?
The primary limitation is the current high cost of LED light bulbs. Even though the cost of Light emitting diode lights is steadily decreasing, startup cost may seem daunting, but Light emitting diode 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.
