I just recently noticed that the ballast on my light fixture is very hot. I mean so hot that you cant pick it up and hold it for more than 2-3 seconds. Is that normal? Ive just recently changed my under tank setup and now have my ballast within reach and ive honestly never felt it while its on before now. Wondering if maybe I need to just change the bulb cuz its drawing more load than it should or if I need to run out and buy a new light hood (and bulb while im at it). Feedback much appreciated!
