LED FAQ

What are the advantages to using Light emitting diode lights?

LEDs has several advantages - high performance and durability, much longer lifespans, reduced upkeep . This translates into energy financial savings, upkeep financial savings and an overall reduction 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 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?

LED Lights never dies out like an ordinary bulb, the individual diodes do not have to be replacesd. 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 lifespan of an LED measured as lumen depreciation?

The lifespan of an LED 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 lifetime is measured by lumen depreciation.

How efficient are led bulbs compared to incandescent bulbs?

Light emitting diode 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 LED'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 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 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 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.
