Coil powered at 3.6 KVA at 12,000 volts with neon transformers, No, I was not standing next to it when it was running. Arc length 3 feet, picture time 1 second total darkness with a flash, no coil power and 2 seconds in total darkness with coil powered. Notice, I have changed the capacitors they are in 12" PVC pipes with transformer oil and are a total of 0.150 mf. The coil is also on a taller platform putting it farther away from the floor and neon transformers. This picture was taken in the dead of winter with a wind chill outside of -20 degrees Fahrenheit.
