Commercial Signage: Commercial signage often operates 12 to 24 hours per day, consuming about 2% of the total electricity in the United States. Fluorescent signs currently account for about 48% of this market, with neon signs holding about 41%, and the remainder of the market dominated by incandescent products.
Institutional, Industrial and Commercial Lighting: LED products can have a significant impact on energy use in airport, ports and roadway lighting, where conventional fluorescent- and incandescent-lit signage is heavily used.
Retail Lighting: LEDs offer unprecedented flexibility in colors and configurations to lighting designers in creating displays and "moods" in retail settings.
