Many of our professional lighting places are gradually replacing the lamp heads of traditional metal halide light sources with LED floodlights. The main features of LED floodlights are high light efficiency, long life, better light color, and strong color rendering. With various advantages such as energy saving and environmental protection, what is the optimal brightness of outdoor LED floodlights?
How many lumens do I need for outdoor flood light?
The overall light effect of a conventional LED floodlight is 100-115lux/W; secondly, the light effect of a slightly higher LED floodlight can reach 120-130Lux/W.
There is no fixed standard answer to the optimal brightness of outdoor LED floodlights, as it depends on multiple factors, including but not limited to:
1. Lighting needs: Depends on the function and purpose of the lighting area. For example, stadiums, large squares, billboards, etc. require high-brightness lighting, which may require thousands or even tens of thousands of lumens; while landscape lighting such as gardens and courtyards may require softer and moderate brightness.
2. Site area and height: The size of the lighting area and the height at which the lamps are installed determine the required light intensity. Generally speaking, larger areas or higher installation heights require higher brightness fixtures to ensure adequate light coverage and uniformity.
3. Lighting standards: Different countries and regions have their own lighting standards and recommended values, such as the guidelines issued by IESNA (Illuminating Engineering Society of North America) or CIE (International Commission on Illumination), which contain recommended illumination and brightness requirements in different application scenarios. .
4. Energy saving and environmental protection considerations: On the premise of meeting lighting needs, try to choose a brightness that can meet energy saving requirements to avoid energy waste and light pollution caused by excessive lighting.
In practical applications, choosing the appropriate wattage of LED floodlights requires considering factors such as usage, irradiation distance, illumination requirements, durability and energy saving.
How to choose outdoor LED floodlights?
1.LED flood light chip
The quality of the chip determines the life and light decay of the LED floodlight. Some domestic chips are of poor quality and cannot be used.
2. LED floodlight housing design
The heat dissipation design of LED floodlights is another important factor. The surface of the aluminum alloy lamp shell in the picture is sprayed with high thermal conductivity paint, which can resist smoke. It has a 180° adjustable mounting bracket, convection design, good drainage and self-cleaning ability, and efficient heat dissipation. .
3. LED floodlight power supply
Relevant specifications have not yet been released, and there are many and varied LED drive power supply manufacturers. Handing LED floodlights use high-performance drive power supplies with a 5-year warranty.
4. Whole lighting effect
Does the LED floodlight have relevant certifications, protection level, light efficiency, and lighting effect? For issues such as service life and years of manufacturer's warranty, use a keen eye to choose lamps of good quality.
