HOW ARE THE DIFFERENT COLORS MADE?
The colors are created in in the following ways: By filling the tube with either of the two gases. They are neon, which appears red-orange in a clear glass tube, or argon, which is pale blue in a clear glass tube. Or, by using a colored glass tube, or a clear glass tube that is coated on the inside with fluorescent powders that, when lit, will emit certain colors. HOW EXPENSIVE IS NEON TO RUN? The electrical power needed to run neon depends on the total length of tubing, the diameter of the tubing, the colors, etc. A typical neon sign or art piece, however, of average size will consume approximately fifty to two hundred watts, which can be compared to the power consumption of an equivalent incandescent bulb. Neon is a very efficient light source. HOW LONG DOES NEON LAST? Most indoor neon pieces are virtually maintenance free. The transformer or power supply can last up to fifteen years, if it is correctly matched to the neon display. The neon tubes do not burn out like incandescent or
