Lost my pair of flame angels to a GFCI trip :(

[Delphinus]

I realize there's a surge but I'm not sure what the peak draw is during the surge. The lights on this particular circuit are one 250W DE and then 4x24W t5's over the 20. Not knowing the surge values, my general strategy has been just to generally try not to overload the breaker, ie., try to keep it no more than half, ie., 7 or 8 amps. I should reassess all the items on it, but at least at time of writing this, I don't think I'm overloading the circuit. If it is a dodgy GFCI, I'll be retiring the hardware soon enough anyhow though, restringing wires, etc., so hopefully it will be a moot point in time.
