I bought one this year. Hope I have better luck with mine. Also got the 69 pro controller. After reading the thread I put a clip fan blowing on the driver to shed heat.
I was dismayed with the update thing since it did it once and was working fine after settings, then updated again and changed the clock and had to use schedule or else wait 24 hours for the light to come back on. 
I have been happy with previous purchases. I own 3 controllers, 3 fans and a tent all AC Infinity. Was not expecting to come across this kind of review of their products. We will see how long this light lasts I guess. I like the graphs available with the controller, the yields have been okay but I have only been on this light since June.
I have not experienced this. Been almost a year though at the time of my startup.
