Project Background
This renovation project targets a standard commercial 7-a-side artificial turf football pitch. The venue has long been open for daily training and small-scale night matches. The original lighting system adopted traditional 800W metal halide floodlights, which suffered from long-term aging, extremely high power consumption and severe lumen depreciation. The old lighting failed to meet modern night training requirements and international match illuminance standards. To reduce long-term operation electricity costs, improve field lighting uniformity and eliminate night glare, the venue operator decided to fully upgrade the entire lighting system to LED. The project retained the original 8m light poles without rewiring, realizing a low-cost and high-efficiency lighting renovation.
Existing Pain Points
Before renovation, the traditional metal halide lighting system of the 7-a-side pitch had four core operational problems, which are common pain points of old stadiums at home and abroad:
1. High Energy Consumption & Heavy Electricity Cost: 36pcs 800W MH lamps operated at full load with huge daily power consumption, resulting in high annual electricity expenditure and compressed venue profit margin.
2. Severe Lumen Depreciation: Short service life of traditional MH lamps caused obvious brightness attenuation within half a year. Uneven field brightness failed to support stable daily night training.
3. Severe Glare & Poor Sports Experience: Without professional light-control lenses, MH lamps produced scattered light with massive waste outside the pitch, causing visual fatigue and sight interference for players during night games.
4. High Maintenance Cost: MH lamps had high failure rate and short lifespan. Aerial equipment rental and manual replacement were required every year, bringing high hidden maintenance costs.
Customized Solution
Combined with the original pole layout, circuit load and sports lighting standards, we customized an integral renovation solution of non-destructive replacement, energy saving & brightness improvement, no rewiring and low maintenance. All outdated 800W metal halide lamps were removed and fully replaced with HRLUX 400W professional bat-wing LED stadium lights.
The project adopted a mature standardized layout: 6pcs 8m standard light poles, equipped with multi-angle circular brackets, 6pcs 400W lamps per pole, 36 lamps in total. With exclusive bat-wing optical lenses, the lights precisely control the projection angle, focusing 92% of luminous flux on the turf to avoid light waste and glare. The lamps perfectly adapt to the original circuit load without rewiring or pole modification, greatly shortening the construction period and reducing renovation cost. Equipped with IP66 full-sealed protection, Meanwell industrial driver and 50,000-hour long-life chips, the lamps are suitable for long-term outdoor harsh environments such as high temperature, rain and sand wind.
Test Data & Project Results
After construction completion, third-party inspectors conducted multi-point on-site night tests. All lighting parameters met and exceeded industry standards. The quantified renovation results are as follows:
1. Greatly Improved Illuminance: The average field illuminance increased from 275LUX to 330LUX (20% brightness improvement), far exceeding the 200LUX minimum standard for global amateur matches, with uniformity up to 0.72 and no dark zones.
2. Significant Energy Saving: The total installed power dropped from 28800W to 14400W, realizing 50% power reduction. Daily power saving reaches 86.4 kWh, reducing annual comprehensive operation cost by 52%-60%.
3. Optimized Optical Performance: Custom bat-wing light control design ensures UGR ≤ 22, completely eliminating harsh glare and providing clear and comfortable vision for night training and matches.
4. Ultra-Low Maintenance Cost: 50,000-hour long-life LED chips require no batch replacement within 5-8 years, completely eliminating annual high-cost aerial maintenance.
Customer Testimonial
“The biggest problems of our pitch were high electricity bills and frequent annual lamp maintenance, which brought great operational pressure. After upgrading to HRLUX 400W professional LED stadium lights, our electricity cost was cut in half. The field brightness is more uniform and glare-free, and players have a much better night vision experience. The most reassuring point is that no aerial maintenance is required for years, and the payback period is shorter than expected. We will continue cooperation for subsequent venue upgrades.”
