Just a thought here,if it is your buddies controller or electric system causing the problem a multi meter should tell the tale pretty quickly,if on the other hand you have full voltage consistently the problem could be in your fixtures.Id check voltage at the panel first and every other connection down the line next.Im with the others thinking its in your system somehow though and not the fixture,ive run alot of gavitas 750s and 1000s and the only issue ive heard of with them has to do with the diagnostic lights on the new e series but it does not affect performance at all,best of luck,FW
