The irradiation distance of a 400W LED flood light is usually between 50-150 meters. The specific irradiation distance depends on factors such as the model, design, use environment and target lighting effect of the lamp. For example, the irradiation distance of a 400W LED floodlight can reach 50-150 meters, which is particularly suitable for landscape lighting of buildings, outdoor squares, walls, parking lots, stadiums, sports fields, etc. The following are some key factors that affect the irradiation distance of a 400W LED flood light:
1. Optical design
•Reflector/lens: A high-quality reflector or lens can effectively concentrate the light, thereby increasing the illumination distance. Narrow beam angles (such as 10° to 30°) generally provide a longer illumination distance, while wide beam angles (such as 60° to 120°) provide a wider coverage area.
2. LED chip quality
•Luminous efficacy: High-efficiency LED chips can output higher lumen values at the same power, thereby increasing the illumination distance.
3. Environmental conditions
•Mounting height: The higher the fixture is installed, the longer the illumination distance. For example, there will be a significant difference in the illumination distance at a height of 5 meters and 20 meters.
• Ground reflectivity: Smooth surfaces (such as concrete) reflect more light than rough surfaces (such as grass), which helps to extend the irradiation distance.
• Weather conditions: Bad weather such as fog and rain will reduce the distance that light can travel.
4. Specific applications
• Application scenarios: Different application scenarios have different requirements for irradiation distance. For example, stadiums, tunnels, commercial lighting, squares, building exteriors, billboards, etc. require different irradiation distances.
Irradiation distance reference Based on the above factors, the irradiation distance of a 400W LED floodlight is roughly as follows:
• Standard floodlight (wide beam angle):
• Irradiation range: about 30-100 meters, depending on the beam angle and reflector design.
• Typical applications: parking lots, warehouses, factories, etc.
• Floodlight (narrow beam angle):
• Irradiation distance: up to 100-300 meters, or even farther, depending on the beam angle and reflector design.
• Typical applications: stadiums, large building exteriors, billboards, etc.
How far can a 400W LED floodlight irradiate? The specific irradiation distance of a 400W LED floodlight may be as follows:
•30° beam angle: maximum irradiation distance can reach 150-200 meters.
•60° beam angle: maximum irradiation distance can reach 80-120 meters.
•90° beam angle: maximum irradiation distance can reach 50-80 meters.
Conclusion The irradiation distance of a 400W LED floodlight can range from tens of meters to hundreds of meters, depending on the design of the lamp, the optical system, the quality of the LED chip, and the installation and environmental conditions. If you have specific project requirements, it is recommended to contact the manufacturer or supplier directly for detailed technical parameters and application recommendations. Hopefully this information will help you better understand the irradiation capabilities of a 400W LED floodlight.
