2 different bulbs tried on HV straight out of microwave oven transformer being driven by a 12volt 555 timer circuit designed for running car ignition coils.

The small car headlamp HID bulb seemed to warm up and then run at lower amps with flashes. It cooled down and stopped. Don't know if this is the cooling we are looking for or just a function of less power allowing it to cool off.

It was awesome to J.R.Roth mentioned finally. He was cool like Peter Hagelstein and would reply to emails; before that unfortunate incident where he couldn't find US grad students, and got in trouble with the military. Thanks Bob, keep doing what you are doing.
