GE Arcstream

It's little of a surprise that it still lights up and still has its original colour, given its hours, and where it was made! I wondered if it's arc voltage/current had altered with the electrode tips burning away slightly, but it's measuring at 135 arc volts @ 1.5 amps, these are still one of the fastest running up discharge lamps I've ever experienced though, literally coming to full output in about 20 seconds!
