Southeast Asian University Arena Transforms Multi-Sport Lighting with Energy-Efficient IP66 Waterproof LED Solution
June 28, 2026
Project Background
A leading university in Thailand operated a 5,000-seat indoor arena that hosted basketball, volleyball, futsal, and badminton competitions alongside graduation ceremonies and cultural events. The existing 400W metal halide high-bay fixtures, installed during the arena's construction 15 years earlier, suffered from poor color rendering, excessive glare during televised events, and high heat output that strained the HVAC system during packed events. With the arena hosting an upcoming regional university games championship, the administration prioritized a complete lighting modernization.
The Challenge
- IP66 waterproof rating required despite indoor installation—the arena's open-side architectural design exposed the ceiling to tropical rain during monsoon season
- Multi-sport versatility requiring adaptable illumination levels for different sports: 750 lux for televised basketball, 500 lux for volleyball, 300 lux for badminton
- Heat management critical—existing fixtures contributed significantly to the arena's cooling load in Thailand's year-round 35°C climate
- Rapid installation required within a six-week semester break window
The Solution: 500W Energy-Efficient IP66 Waterproof LED Stadium Lights
The university selected 36 units of 500W Energy-Efficient IP66 Waterproof LED Stadium Lights with 60-degree beam optics, ceiling-mounted across the arena's 18-meter-high roof structure. The LED system incorporated a DALI-compatible dimming control interface allowing lighting scenes to be pre-programmed for each sport, event type, and broadcast configuration.
| Key Specification | Performance Achieved |
|---|---|
| Maximum Illuminance | 820 lux (basketball mode) |
| Uniformity Ratio | 0.78 (Emin/Eavg) |
| CRI | ≥80 (vs. ~65 on previous MH) |
| Total System Power | 18 kW (vs. 52 kW previously) |
| Heat Load Reduction | ~34 kW thermal reduction |
| Flicker Rate | ≤0.3% for broadcast cameras |
Results & Impact
- Energy Efficiency: 65% reduction in lighting power consumption, with additional HVAC savings from reduced heat load estimated at 15% of pre-retrofit cooling costs
- Multi-Sport Flexibility: DALI dimming enables instant switching between competition lighting profiles, eliminating the 15-minute warm-up/re-strike delays of the previous HID system
- IP66 Protection Validated: During a severe monsoon storm, wind-driven rain penetrated the arena's open sides, yet all fixtures maintained full operation with zero water-related failures
- Broadcast-Ready: The regional university games were successfully broadcast in HD across Southeast Asia, with the organizing committee specifically commending the competition-standard lighting
- Student Experience: Athletes and coaches reported noticeably improved ball tracking and depth perception under the high-CRI LED illumination
Facilities Director Feedback
"This was the most transformative single infrastructure upgrade we've completed in the arena's 15-year history. The instant-on capability alone has changed how we schedule events, and the energy savings have already funded additional improvements to our strength and conditioning center."
