| Price the complete lighting and electrical package |
Request a fixture schedule with quantity, input power and warranty; pole or mounting details; trench and cable lengths; distribution-panel work; controls; installation; and commissioning. Confirm whether the court package includes these items or only the luminaires. A distant power supply or panel upgrade can change the installation budget without changing fixture count. |
Ask for a photometric plan: a calculation showing illumination, uniformity, glare and light spill for the proposed layout. More fixtures do not by themselves establish acceptable playing conditions. LTA/SAPCA guidance calls for a lighting design and performance documentation; local electrical rules and restrictions on spill or operating hours must be checked for the site. |
| Calculate running cost from power and use hours |
Annual lighting energy cost = total fixture input power in kilowatts × annual lighting hours × electricity price per kilowatt-hour. Add control equipment or other loads where relevant. Use lighting hours rather than all opening hours, and use the actual electricity tariff, including demand charges where applicable. |
Hypothetical example, not a lighting specification or market tariff: eight 200-watt fixtures total 1.6 kW. At 1,000 hours a year and $0.20 per kWh, energy costs $320 per year. At 2,000 hours the same assumptions produce $640. These figures exclude installation, maintenance, taxes and demand charges. |
