What are the pros and cons of chip-on-board vs SMD LEDs in stadium floodlights?
Choosing between COB and SMD LEDs is an important consideration when selecting high-power stadium floodlights. Both technologies have advantages, but their suitability depends on power level, optical requirements, thermal design, and the intended sports application.
COB vs SMD for Stadium Lighting
COB (Chip-on-Board) integrates multiple LED chips into a compact light-emitting surface. It can provide high light density and a relatively compact optical source, but concentrated heat management and optical control can become more challenging at very high power.
SMD (Surface-Mount Device) uses individual LED packages distributed across the fixture. This provides greater flexibility for optical design, heat distribution, maintenance, and different beam configurations.
For large sports facilities requiring precise light distribution, SMD can offer practical advantages.
Why FORTOMO 40SL Uses SMD5050
The 40SL 500–750W LED sports light uses SMD5050 LM80 LEDs , with options including Lumileds, CREE, and selected local brands. It delivers 150–170 lm/W and supports multiple beam angles for sports lighting applications.
The 40SL also uses a pure AL1070 cold-forged aluminium housing with an airflow-oriented design to improve heat dissipation. This thermal structure is particularly important for 500W–750W high-power floodlights.
Which Is Better for Stadium Floodlights?
There is no universal winner. COB can be useful where a concentrated light source is preferred, while SMD is often advantageous for high-power sports floodlights requiring flexible optics, distributed heat management, and precise beam control .
For stadiums, football fields, high-mast installations, and large sports grounds, the complete system—including LED package, thermal design, optics, driver, and housing—should be evaluated rather than choosing based solely on COB or SMD technology.
