About the Light Emitting Diode
A light-emitting diode (LED) is a semiconductor device that emits visible light when an electric current passes through it. The tiny diode fits easily into an electric circuit. Unlike ordinary incandescent lamps, they do not have a filament that burns out or gets hot. individual LEDs are binned and then clustered on a circuit board to create an array, which is then incorporated into a lamp.
Why such a price difference on LED lamps?
Tighter binning tolerance = More $
LEDs are created as a flat sheet, known as a wafer. Then they are separated into tiny “chips” and binned according to three characteristics:
- Color temperature
- Lumen output
Quality of LED Light
LED light is different than halogen light. Some manufacturers may tell you that they are the equivalent to halogen. They are close, but they are not exactly the same. There are two main lighting characteristics that help define the quality and consistency of LED light
CRI & CCT
Color Rendering Index (CRI) describes how a light source makes the color of an object appear to human eyes and how well subtle variations in color shades are revealed. The CRI is a scale from 0 to 100 percent indicating how accurate a “given” light source is at rendering color when compared to a “reference” light source. The higher the CRI, the better the color rendering ability. Halogen is considered the “reference” light source and has a CRI of 100.
CRI of 100 in an LED source has not yet been developed. CRI in the 90’s is possible but very expensive.
Fluorescent lamp sources are considered very poor in CRI running in the low 70’s. A CRI index >80 is considered very good. FLEX GOLD™ Series high-powered LED lamps have a CRI between 82 and 84.
What is L70?
L70 pertains to the life expectancy of the LEDs. When CREE and other LED manufacturers project a “40,000 hour life” it is based on when an LED source deminishes light output down to a 70% light level, compared to its initial lumen output. For example if an LED starts illuminating at 100 lumens and after 40,000 hours it only emits 70 lumens (70% of the original output) then the L70 estimated life of this LED is 40,000 hours. Environmental Testing
In addition to the LED testing, the FLEX GOLD™ Series lamps have also passed extensive water/moisture, high ambient, cycling and electrical testing.
CREE LED Chips
FLEX GOLD™ Series high-powered LEDs are manufactured by the leading LED lighting manufacturer, CREE. CREE’s LED withstands the difficult and long term LM-80 testing. The LM-80 test criteria was developed by the IES and is the LED industry standard for developing the lifespan rating for LEDs. The FLEX GOLD™ Series high-powered LEDs are rated at 40,000 hours.
FLEX GOLD™ Series Thermal Management System
After an LED passes the LM-80 testing, it must also pass the LM-79 testing within the final product. This confirms that the LED is properly managed and run from a thermal standpoint. While LEDs do not give off “forward heat” like a traditional halogen source, they do get hot. If they run too hot their lifespan may be shortened. Thermal management is actually the key to their long life. The FLEX GOLD™ Series Thermal Management System controls heat and dissipates the heat away from the LED itself. The result is a very long life, even at elevated ambient temperatures that you might see in warmer climates.
