Usually, in some large-scale commercial or industrial areas, bay lighting is a kind of lighting that we can often see. These lamps do not look much different in appearance, but in fact, bay lighting is divided into low bay lighting and high bay lighting. In order to avoid choosing the wrong bay lighting, we need to be clear about the difference between them.
What is the bay lighting?
Bay lighting is lamp equipment used to illuminate large commercial or industrial spaces, such as factories, warehouses, stadiums, train stations, etc. The bay lights will provide even and evenly distributed light in open areas.
Common light sources for bay lighting include traditional 75W 150w, 250W, 400W, 500W, and 1000W metal halide lamps, which emit 360-degree light, with low light efficiency and serious light loss. At present, LED light source lamps have become a new generation of energy-saving light sources with the most advantages to replacing traditional light sources in the world. Therefore, LED bay lights have directional light emission, low power consumption, good driving characteristics, fast response speed, high shock resistance, long service life, and green Environmental protection and other advantages will become the best choice for energy-saving transformation in traditional large-scale space lighting, and it is also the general trend.
The main differences between low bay lighting and high bay lighting are as follows:
- Different luminous flux and different illuminance.
The biggest difference between low bay and high bay lights is the difference in luminous flux. In real life, the luminous flux of low bay and high bay lights does not have a correct dividing line. According to industry experience, those with effective luminous efficiency below 8000lm can be used as low-bay lights (for example, 50W led low-bay lights); those with more than 8000lm can be called high-bay lights, which are popular 100W 150W 200W UFO high-bay lights on the market.
- Different installation height
Low bay lights are suitable for installation in large spaces with a height of 10ft-20ft. In this space, low bay lights can not only provide enough brightness but also can replace the cost of lighting.
In the 20ft-50ft space, high bay lighting is the most suitable choice.
- Different beam angle
Because the height of the place required for low-bay lighting is generally low and the illumination requirement is relatively low, it is generally suitable for a large light-emitting angle, about 120°. This light-emitting angle can alternatively expand the irradiation surface to reduce the number and cost of lamp installation.
For high bay lights installed in higher places, in order to maximize the illuminance of the working surface or the ground, it is necessary to use a 45°, 60°, or 90° reflector with a condenser function (UFO LED high bay lights usually Use lenses to achieve condensing), gradually to provide sufficient brightness.
- Different Application
Low bay lights are common in some large spaces but low commercial and industrial places, such as grocery stores, retail stores, schools, gas stations, etc.;
It is indeed a high bay light commonly found in large industrial sites such as factories, warehouses, and stadiums.
- Different types
From types, the low bay light has been more choices than high bay light. The high bay includes ufo type, linear high bay, but for the low bay, except for the above type, there are still including troffer low bay, E27/E40 Low bay bulb lights, etc.
