Generate Bolts of Lightning
Crashing Against the Inner Walls of a 5" Lamp!

Great for science fairs and small HV experiments, an attention-getting office or bar action decoration, a conversation piece, or other special effects prop. Produces an adjustable repetition of high voltage open-air spark discharges of up to several cm.

Unit is built into a 3 x 2 x 1" plastic box and is powered by a three wire grounded line cord operating from 110 vac. As a safety measure the output winding is directly connected to the earth grounded green lead of the power cord. This prevents any accidental contact to the 115 vac that could occur by accident or by a circuit fault.

Power and repetition rate are controlled by a combination potentiometer and switch. Output voltage pulses are up to 40 kv at .2 Joules and can be adjusted from a slow to fast pulse rate. Sparks are very audible and visual for the small size of this unit.
