Get a meter and check the voltage, then turn on all the equipment and check the voltage again. I'd be willing to bet there's a decent sized voltage drop. Less voltage=more current(amps), eventually things burn up when the current gets high enough above what it was designed for. What voltage is he running the ballasts on? If he's running them on 120, changing them to 240 will definitely cure the voltage drop, unless it's already really low to begin with.
Thanks bro I appreciate all the help but much more useful when there are some specifics.. The wiring, the outlets, and the breaker possibly I knew in my own.. At the risk of sounding like an ass I don't know what other then those that it could be other then doing something deliberately to it causeing them to die.. Because his room does not have anything crazy going on so it was obvious it was electrical.. So again thank you everyone for the responses.. Son son thanks for the help.. He is at 120. If he rigs the outlet for the 240 he should be good? Sorry when it comes to the actual houses electrical system im not the brightest bulb in the hood lol and when you say check frequency as in if he goes the 240 route check it because that will/ could somehow change it of check it now? Also by adding the surge protector will it protect from drops or just surges? Again thanks for the help brother especially with the cost of these ballast and more importantly my safety..
