	Area lighting illuminates specific areas significant to traffic guidance within the temporary traffic control zone during nighttime hours. Lighting of this nature is required at flagger stations and may be considered at gore areas, transitions, ingress and egress areas, equipment crossings, intersections, and temporary signals. A minimum intensity of 5 foot-candles in the specific area is recommended for this type of lighting. Typically, this lighting is provided by a single light on a portable lighting unit or mounted on a temporary pole. As with work lighting, lighting shall be positioned so that it does not cause glare for motorists, spill onto adjacent properties, create shadows or become a safety concern. Flagger stations in operation at night are required to be lit.

	When nighttime work is being performed, lighting should be used to illuminate the work area, equipment crossings and other areas. The amount and location of light provided for the work area is based on the type and detail of work being performed and the degree of difficulty in navigating the work zone. Minimum required intensity for flagging operation activity is 5 foot-candles. (One foot-candle equals the amount of light delivered by a 1-candela light source to a 1 sq. ft. surface 1 ft. away). Work area lighting provides a minimum maintained intensity of 5 foot-candles (54 lux).
