Custom Indoor Court LED Lighting | Houston Sports Club

Q: What is the expected lifespan of the new LED court lighting?

The custom luminaire, utilizing Bridgelux chips and a Mean Well driver, is engineered for a long operational life. The system has a calculated L80B10 lifetime of over 60,000 hours, which translates to more than 13 years of operation at a typical usage of 12 hours per day, minimizing the need for maintenance.

Q: How does the new lighting system handle potential power surges or fluctuations?

The specified Mean Well ELG series drivers include built-in overvoltage, short circuit, and over-temperature protection. Furthermore, we recommended the installation of a Type 2 Surge Protection Device (SPD) at the lighting panel to protect the entire system from external power grid events up to 20kA.

Q: Were different color temperatures considered for the project?

Yes, we modeled both 4000K and 5000K options. The client selected 5000K, as it provides a crisp, daylight-like environment that enhances player alertness and visual acuity. This CCT is also preferred for sports broadcasting, providing excellent color rendition on camera with a CRI exceeding 85.

Q: Can the lighting be controlled remotely or integrated with a building management system (BMS)?

Absolutely. The DALI-2 protocol is an open standard designed for interoperability. The system can be connected to a BMS via a DALI gateway. This allows for centralized scheduling, energy monitoring, and remote diagnostics, providing the facility management team with complete control over their 150+ new luminaires.

Introduction — the On-site Problem

com), a Custom Indoor LED Lighting Manufacturer based in China, we were approached to develop a comprehensive lighting upgrade for the main indoor multi-sport court at a prestigious Houston Sports Club. The existing metal halide system, installed over a decade ago, suffered from poor light uniformity, significant glare (UGR>25), color shifting, and high energy consumption.

These issues were negatively impacting player visibility and safety during fast-paced sports like basketball and volleyball, and the club sought a modern, high-performance LED solution compliant with international sports lighting standards ahead of its 2026 facility-wide renovation.

What "custom" Meant on This Project — Capability Matrix

For this project, a standard off-the-shelf high bay was insufficient. The client required a luminaire tailored to the specific geometry of the court and the demands of televised events.

This involved customizing the optics, housing, and control integration. The target specifications for the primary custom linear high bay luminaire are detailed below.

Engineering Solutions

Our engineering process focused on solving three key challenges: achieving world-class visual comfort, providing operational flexibility, and ensuring long-term durability in a demanding sports environment.

How Did We Achieve Professional-level Uniformity and UGR<19 for Fast-paced Sports?

Glare is the enemy of performance in court sports. To meet the stringent UGR<19 design target, our optical engineers selected a specialized asymmetric beam distribution.

This directs light downward onto the court surface while minimizing high-angle light that causes glare for players and spectators. We used advanced ray-tracing software to model fixture placement and aiming angles precisely.

What Was the Strategy for Integrating DALI-2 Control for Flexible Court Use?

The Houston Sports Club hosts a variety of events, from professional-level competitions to community practice sessions and non-sporting events. A one-size-fits-all lighting level is inefficient.

We integrated DALI-2 digital drivers into every luminaire. This allows for granular control, enabling pre-programmed scenes accessible via a simple wall-mounted controller.

The proposed scenes included: 'Competition' (100% output, 750 lux), 'Training' (60% output, ~450 lux), 'Recreational' (40% output, ~300 lux), and 'Maintenance' (20% output). This strategy is projected to deliver an additional 25-30% in energy savings over a simple non-dimmable LED solution.

Why Was a High-impact IK10 Rated Housing Specified?

Standard commercial luminaires are not built to withstand the physical abuse common in sports facilities. A stray basketball, volleyball, or other piece of equipment could easily shatter a lens or damage a fixture, creating a safety hazard and requiring costly repairs.

We designed the luminaire housing using high-purity die-cast aluminum and a reinforced polycarbonate lens, achieving an IK10 rating. This is the highest level of impact protection under the EN 62262 standard, meaning the fixture can withstand impacts of up to 20 joules, ensuring safety and operational continuity.

Project Results — Measured When Supplied; Otherwise Design Targets

As this project is scheduled for completion in 2026, all results are based on engineering design targets and validated simulation models. The proposed solution is designed to achieve the following outcomes:

Illuminance Level: A target average maintained illuminance of 750 lux across the primary playing surface.
Light Uniformity: A target minimum-to-average uniformity ratio (Umin/Uavg) of >0.7, eliminating dark spots and ensuring consistent play conditions.
Glare Control: A simulated Unified Glare Rating (UGR) of <19, compliant with standards for professional indoor sports.
Energy Savings: A projected energy consumption reduction of over 65% compared to the previous metal halide system, with a projected payback period of under 3 years based on energy and maintenance savings.
Broadcast Readiness: The system is designed to meet the vertical illuminance and Television Lighting Consistency Index (TLCI) requirements for future HDTV broadcasting.

Photometric Files & Compliance (IES / LDT / DIALux / CE / RoHS)

Full transparency and engineering validation are core to our process. For the Houston Sports Club, complete IES and LDT photometric files were generated for the custom luminaire, allowing for independent verification by the client's consultants.

The comprehensive DIALux simulation report, detailing point-by-point illuminance, uniformity grids, and UGR calculations, was submitted as part of the formal proposal. All specified components and the final assembly will be fully compliant with CE and RoHS directives, and our manufacturing process is certified under ISO9001:2015 for quality management.
