Calling all lighting experts, my Sunpod HQI 14K 75W dual sided like has started flickering.  It just started this morning so I shut the light off for a few hours and turned it back on to find it doing it again 30 mins later.  
Any ideas what might be causing this? I my light going bad or the entire unit?
