Am I missing something here? I bought this Megaray self ballasted 100w and a few days in the thing starting flickering on and off.... I unscrewed and re-screwed it the first time thinking it was loose or something n fixed it... now it just keeps flicking on and off when it warms up after being turned on....... Am I missing something here??? WTF!?!? I waited over a month to recieve this thing due to "TESTING EACH ONE BEFORE THEY SELL/SHIP" and now this??? Is it the dome? Iv'e tried the two that i already had thinking it was the dome... My other bulbs work fine in it....
