Does neon use a lot of electricity?
No, because neon lights do not produce much heat. The light emitted is of a narrow bandwidth, that is why it is so bright. Neon is among the most efficient type of lighting produced. Although the voltage to operate a neon sign is high, the current used is very low making the overall power used a small amount. The average neon sign only consumes about .8 amps ( 8 tenths of an amp). This equates to about 96 watts. Average cost to operate your neon sign is only about 20 cents per day, if you operate it 24 hours per day. You can run 72 feet of neon for about the same price you would pay to run 8 feet of hot cathode (fluorescent).
