Lighting

ATP

a) ATP World Tour Tournaments. Lighting must be evenly distributed on the court with a minimum recommended intensity of 100 foot-candles (1076 LUX), averaged over 15 readings on court.

The recommended minimum lighting for televised events broadcasting in high definition is an average of 285 foot candles (approximately 2,000 lux).

The light should be distributed across the court evenly with a consistent color temperature.

b) ATP Challenger Tour Tournaments. Lighting must be evenly distributed on the court with a minimum recommended intensity of 70 foot-candles (750 LUX), averaged over 15 readings on court.

3) High/low ratio. A ratio of the highest to lowest readings should be no greater than 1x2.0 but the recommended ratio is 1x1.5

4) Light poles. Light poles should be positioned so that they are evenly distributed around the court and it is recommended that light pole heights for other than show courts be no lower than forty (40) feet (12.19 m.) or no lower than other non-show court lights at the facility, e.g., if others are sixty (60) feet (18.29 m.), then new lights should be sixty (60) feet (18.29 m.) high.

5) The supervisor has the authority to suspend play on any court if the intensity of illumination, in his judgment, is insufficient for professional tennis.

WTA

(a) Each Tournament shall cause all Matches staged on courts where televised Matches are staged to be lighted in a manner such that high quality, colour telecasting can be conducted.(b) To the extent any Matches are staged on courts other than those equipped to be lighted for television production, the WTA (or its designee) shall be responsible for the costs associated with any lighting (including equipment) that may be required for such matches.(c) If the Tournament is held indoors, the Tournament shall cause the use of strobe lights on any "still" photographic equipment to be discouraged at the site. The indoor playing surface must be illuminated evenly at a minimum 1076 lux. The light source must be from either side of the court and must not be perpendicular to the inside of the playing area. The best type of lamp source is a tungsten lamp with a color temperature of 3200 Kelvin. The tungsten light source offers a far more stable color temperature than discharge lamps and is far more reliable. The most suitable luminaries are flood lights with a symmetrical reflector and 1.5 kw. Depending upon the reflective values of surfaces within the area and the distance between the luminaries and the playing surface, 60-80 (30-40 on each side) luminaries are required. If 80 lamps are required, the total power requirements are 120 kw. A venue requires a minimum of 200A 415V supply.

Davis Cup

Play is allowed with artificial lighting in the open air after sunset or on covered courts provided there is a minimum of 500 lux per square metre (1,200 lux in the case of the World Group), evenly distributed over the court surface, and practice facilities for both tennis teams with similar lighting are available. All measurements are to be taken one metre above the playing surface.In exceptional circumstances when play is on covered courts, this minimum may be reduced provided that the approval of the Davis Cup Committee is obtained. Applications must reach the ITF as soon as possible after the draw or the completion of the previous round and at least six weeks (eight weeks in the case of Ties in the World Group) before the date fixed for the commencement of the Tie, whichever date is earlier.
