Light's of America review: 4' led shop light

I purchased the light because on the box it says 50, 000 Hr rated life. After about 1.5 years of occasional use 4 LEDs are out and four more are flickering. I am not happy about this, but there is little I can do other than spend lots of time and effort tracking down the warranty, then removing and re-installing a new light. I will switch to another brand of LED shop light and install it in the place of Light's of America product.
