How to Replace Old Metal Halide Stadium Lights with LED Sports Lights?
Many stadiums and outdoor sports fields still use older metal halide floodlights that consume significant energy and require regular maintenance. Replacing them with LED sports lights can improve energy efficiency, lighting control, and long-term operating performance.
For retrofit projects, however, the LED wattage should not simply be selected by matching the old metal halide wattage.
What Should Be Considered Before a Retrofit?
The appropriate LED replacement depends on several project conditions:
- Existing metal halide wattage
- Mounting height
- Field dimensions
- Existing fixture positions
- Required illuminance
- Lighting uniformity
- Beam angle
- Existing electrical infrastructure
A photometric assessment can help determine whether the existing number and position of fixtures can be retained or need to be changed.
40SL for Metal Halide Retrofit Projects
The 40SL 500W–750W LED sports floodlight can be considered for medium and large outdoor sports fields.
It is suitable for applications such as football training grounds, outdoor arenas, and sports facilities where high-output LED floodlighting is required.
Depending on the existing lighting layout, a 40SL configuration may replace older medium-to-high-power metal halide fixtures while providing more controlled optical distribution.
46SL for Larger Stadium Retrofits
The 46SL 500W–1500W LED high mast light is designed for larger stadiums, football fields, sports complexes, and high-mast applications.
It can be considered when replacing high-power metal halide floodlights installed at greater mounting heights. The available power range provides flexibility when designing retrofit systems for different field sizes and lighting requirements.
Do Not Match Wattage One-to-One
A 1000W metal halide lamp does not necessarily require a 1000W LED replacement.
Metal halide systems can have additional losses from the lamp and ballast, while LED fixtures provide more controlled light distribution. The correct replacement should therefore be based on actual photometric performance rather than wattage alone .
Use IES Data for Retrofit Planning
Before ordering in bulk, contractors can use IES/LDT photometric files to simulate the proposed LED replacement in DIALux.
FORTOMO can provide IES/LDT data and DIALux lighting simulation support for applicable models, helping project teams compare fixture quantity, illuminance, uniformity, mounting height, and beam distribution.
A Practical LED Retrofit Strategy
For stadium and sports field upgrades, the best approach is to evaluate the existing metal halide system first and then select the appropriate LED configuration.
With 40SL 500W–750W and 46SL 500W–1500W , FORTOMO provides flexible options for different outdoor sports retrofit projects, helping distributors and contractors move from outdated metal halide lighting toward more efficient and controllable LED sports lighting.
