How to Select the Right LED Wattage Based on Installation Height?
According to the source document, selecting the appropriate street light wattage mainly depends on the installation height (pole height) , application scenario, and the required lighting coverage area.
Below is the recommended LED street light wattage configuration guide based on different installation heights.
1. Low-Height Lighting (3M – 5M): Suitable for Pathways & Gardens
For shorter poles, typically used for residential pathways, garden landscaping, bicycle paths, and sidewalks.
|
Parameter |
Recommendation |
|
Recommended Wattage |
20W – 30W |
|
Lighting Coverage |
Approximately 10m – 15m diameter area |
|
Typical Series |
– MELODY (20W): Recommended height 5m–6m |
2. Medium-Height Lighting (6M – 8M): Suitable for Residential & Urban Streets
This is the most common height range for urban streets, commercial parking lots, schools, and rural roads.
|
Parameter |
Recommendation |
|
Recommended Wattage |
40W – 60W |
|
Lighting Coverage |
Approximately 15m – 25m diameter area |
|
Typical Series |
– MELODY (40W-60W): Recommended height 6m–10m |
3. High-Height Lighting (10M – 12M): Suitable for Highways & Large Areas
Used for highways, expressways, large industrial zones, sports stadium perimeters, and ports.
|
Parameter |
Recommendation |
|
Recommended Wattage |
80W – 120W |
|
Lighting Coverage |
Approximately 25m – 40m diameter area |
|
Typical Series |
– MELODY (80W): Recommended height 10m–12m |
4. Very High / High-Mast Lighting (20M – 50M): Suitable for Large Open Spaces
For areas such as container terminals, airport aprons, cargo yards, and sports stadiums, high-mast poles are required, typically equipped with a set of high-power floodlights.
|
Parameter |
Recommendation |
|
Recommended Wattage |
300W and above for such applications. For example, a 300W street light can provide up to 36,000 lumens, making it suitable for large public projects. |
Other Key Factors to Consider When Selecting Wattage
|
Factor |
Description |
|
Luminous Efficacy |
Different models have different efficacy ratings (e.g., from 140 lm/W to 200 lm/W). The higher the efficacy, the higher the brightness provided at the same wattage. |
|
Environment & Climate |
– Sunny regions: Standard configurations are typically designed based on an average of 5 hours of sunlight per day. |
|
Smart Features |
Optional PIR or radar sensors can reduce brightness when no one is present (energy-saving mode), thereby extending battery operating time. |
Summary Recommendation
For specific project planning, it is highly recommended to use Dialux lighting simulation software to perform precise calculations based on road width and required lighting class. This ensures optimal lighting uniformity and safety.
