Rigorous Testing

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™ Series lamps have also passed extensive water/moisture, high ambient, cycling and electrical testing.

CREE LED Chips
FLEX™ 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™ Series high-powered LEDs are rated at 40,000 hours.

FLEX™ 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™ 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.
