How much does it cost to operate a neon sign?

Neon signs are extremely efficient. The reason they look so bright is because all of the output is focused within a small wavelength band of light. The average neon sign only consumes about .8 amps ( 8 tenths of an amp). This equates to about 96 watts (about equal to a single light bulb). Average cost to operate your neon sign is only about 20 cents per day (if you operate it 24 hours per day).
