SpellBrite is low voltage and low risk compared to neon. The voltage of neon signs typically runs in the 9,000-12,000 range and can run up to 15,000 volts. Plus, neon tubes are made of glass and the potential for breakage puts employees, customers, window washers and property at risk. You can clean SpellBrite with a cloth without fear of breakage. In addition, most neon signs contain mercury, which is restricted or outlawed in many places.
