What is the lifetime of LED light panel made by CUTCNC?

http://www.cutcnccam.com/article-show-20121020104134.shtml
The life time of LED light panel is determined by the life time of the LED lights installed which are rated at 70,000-100,000 hours under rated temperature (less than 60 degrees), or 16-22 years if lit up for 12 hours a day.
It should be noted, however, that the actual life time of LEDs depends on the ambient temperature. LED light panels are installed with aluminum heat sinks to dissipate heat generated by LEDs to maintain a lower working temperature, which greatly extends lifetime of the LED light panel. When installing  LED light panel, try to keep the aluminum heat sinks in contact with other metal plates, if possible, to further dissipate heat.
CUTCNC offer V-cut machine to make LED light panel. For details, pls consult our staff.
