I originally plug them in series(4 wires in one end cap) the ballast was running hot and the end caps also( fingers on it maybe 3-5 sec)

then now i try to do them in parallel (2 in each endcaps and according to fulham is underdriven) and the ballast is still as hot but the endcaps are a bit cooler but it is definately not as bright as in series.

my bulb and ballast are around 3 months


but i just got one question that im worried. since fulham doesnt approved the wiring in series. what if something happens and the insurance wont pay since is not wired accordingly.?

Hey Brad, did you resolve this issue? What was the problem? Do you think maybe the endcaps shift over time and got farther apart and you ended up with arcing on 1 end which made that end of the bulb really really hot?

Sam, I ended up replacing th eVHO tubes with the NO philips tubes, and mywiring was a bit "unconventional", me thinks. I don't think the end caps shifted at all, they seem pretty solid and tight. I really can't recall what was wrong with my wiring, but I did change something.

you only had one pin hooked up out of the two. so it was forcing all your current to use 1/2 the normal path and ended up frying the pin.
