Frequently Asked Questions (FAQ)
1. What is the best LED street light?
The best LED street light depends on the application rather than the highest wattage or lowest price.
When selecting a street light, consider:
- Road classification
- Pole height
- Required illuminance
- Beam distribution
- Luminous efficacy
- IP protection rating
- Driver quality
- Warranty period
For municipal and commercial projects, choosing a professionally designed luminaire with high-quality components generally provides the lowest lifecycle cost.
2. How many watts should a street light be?
There is no single standard wattage.
Typical recommendations include:
- 20–30W for pathways and residential roads
- 50–70W for community roads
- 100W for urban main roads
- 150–200W for highways and industrial areas
- 250W for high-mast or large-area applications
The correct wattage should always be selected together with the appropriate optical distribution and pole height.
3. How many lumens does an LED street light produce?
Lumen output varies by product design.
Typical values include:
- 20W: approximately 2,400–3,000 lumens
- 50W: approximately 6,000–7,500 lumens
- 100W: approximately 12,000–15,000 lumens
- 150W: approximately 18,000–22,500 lumens
- 200W: approximately 24,000–30,000 lumens
Always compare both lumen output and luminous efficacy rather than wattage alone.
4. What IP rating should outdoor street lights have?
For most commercial outdoor applications, IP65 is considered the minimum acceptable protection level.
For highways, coastal environments, ports, airports, and industrial zones, IP66 is generally recommended because it provides greater resistance to heavy rain, dust, and harsh environmental conditions.
