How to choose a floodlight?

Clarify the use of the scene 
Outdoor lighting needs to give priority to waterproof performance, IP65 level can cope with heavy rainfall, while the pool around the need for IP68-rated waterproof products; construction sites at night to take into account the brightness and durability, it is recommended to choose industrial-grade floodlights with impact-resistant shells; commercial window displays pay more attention to the light colour rendering, the CRI (Colour Rendering Index) higher than 90 of the product can be a true reproduction of the commodity colours. In addition, the power supply capacity of the installation environment should also be confirmed in advance to avoid circuit failure due to overload.
Core parameters determine the performance 
brightness, do not blindly pursue high wattage, need to be combined with the irradiation range of calculation: 100 square metres of venues to choose 200-300W can meet the basic lighting, while large stadiums need more than 1000W of professional floodlights. The choice of colour temperature is also critical, 3000K warm yellow light for the courtyard to create a warm atmosphere, 6500K cold white light is suitable for construction sites and other scenes that require high-definition recognition. The beam angle parameter is often overlooked. Narrow beam (15°-30°) is suitable for highlighting building contours, while wide beam (60°-120°) is more suitable for large-area floodlighting.
Intelligent functions enhance the using experience 
Floodlight with light-sensing control can automatically sense the brightness of the environment to open and close, which significantly saves electricity; the remote APP control function is convenient for users to adjust the brightness and colour temperature indoors, which is especially suitable for high-pole installation scenarios. It is worth noting that the heat dissipation design directly affects the service life, and products with finned aluminium heat sinks have better heat dissipation.
The core logic of choosing a floodlight is ‘demand matching’: clear use of the scene → lock the key parameters → screening additional features → verification of quality assurance. Following this process can avoid wasted functions and also ensure that the lighting effect meets expectations.
