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 upkeep. These advantages makes Light emitting diode lights a much easier and cheaper option to run over the course of its lifespan.
What's the difference between efficiency 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 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?
An LED does not burn out like a typical lamp, so individual diodes do not need to be replaced . Instead, the diodes gradually produce lower output levels over a very long period of time . If one LED fails, it does not require a complete fixture outage.
Why is the lifetime of an LED measured as lumen depreciation?
The lifespan 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 lifespan is measured by lumen depreciation.
How efficient are led bulbs compared to incandescent bulbs?
Most led light bulbs are five to six times as efficient as incandescent bulbs. In other words, they use only 10% to 20% as much electrical power to produce the same amount of light . 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?
LED'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 creates - 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 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 electrical energy used.
For businesses, using LED lights makes a whole lot of sense since the reduced upkeep costs more than make up for the steep start-up costs.
