LED - Frequently Asked Questions
How long is 50,000 hours?
Based on how long a fixture is illuminated per day, here’s what 50,000 works out to:
24 hours a day - 5.7 years
18 hours per day - 7.6 years
12 hours per day - 11.4 years
8 hours per day -17 years
What is an LED?
LED is the common abbreviation for a light-emitting diode. Each individual LED consists of a semiconductor diode that emits light when a voltage is applied to it. The electronics industry has used LED 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 LED lights?
LEDs has several advantages - high efficiency and durability, much longer life spans,, reduced maintenance.. This translates into energy savings, maintenance savings and an overall reduction in cost of ownership over the product’s lifetime.
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 LED diodes?
An LED does not burn out like a standard 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 produce 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 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 electricity to produce the same amount of light. The newest generation of LED's are eight to ten times as efficient as incandescent bulbs. We use these new leds in some of our products.
What happens when the bulb burns out?
LED's do not burn out like typical light fixtures - they gradually degrade over time. Our 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.
