Fails in less than 3 months.

I've been using these for a little over 2 months now and have noticed that one half of the lights will shut off. (pic included) When it happened the first time I figured ok maybe a heat issue, I power cycled the units and the leds will power back on but with power cycling it resets the on board timer and within another hour or 2 it will shutdown half the board again. I purchased 2 of these units at the same time and they both have the issue.
