  • Eco-friendly. LED industrial high bay lamps use solid LED chips as the light source, which do not contain toxic gases such as mercury and sodium, and will not cause environmental pollution. At the same time, the broken LED high bay lights can be recycled and reused.
  • Higher protection grade. LED high bay lighting adopts aluminum as body, PC, or Tough-glass as cover, it can be IK08 anti-corrosion and IP65 waterproof. What is more, it is also with explosion-proof function.
  • Higher efficiency. The lumens output of LED high bay lights can be up to 160 lm/W Max. 100W LED high bay can replace the traditional 250W metal halide canopy light. Energy saving is more than 60%.
  • Lower cost. LED high bay lights are more energy-efficient. The total cost of electricity saved each year will be much lower than that of traditional high bay lights.
  • Convenient installation. There are many different installation accessories for LED high bay, such as suspension/surface mounted.
  • Instant start. LED lamps use a LED power supply to start, without any rectifier or ballasts, do not need to preheat before work, it can be an instantaneous start, can also be an instantaneous shutdown.
  • More realistic lighting. The color rendering index of LED high bay lights is above 70%, and some can reach 90%. It can better express the true color of the illuminated object.

Frequently Asked Questions

Different places or workplaces have different standards and requirements for illumination. So you need to know clearly the following things before you purchase a high bay LED lights:

  • Where will you install these led bay lights? Generally, a high bay light is suitable for warehouses, gyms, or factories. In these places, the illumination standard is different. For example, for a warehouse, the illumination is range from 15 lux to 75 lux, but for factories, it has to range from 75 lux to 300 lux. 
  • Make drawings of your place, and check how height will you install them.
  • Taking the IES file to do DIAlux according to illumination standard and your building dimension, then you will get the actual quantities you need to purchase.

We are the best LED high bay lights manufacturer in China, it is available to provide the IES file and also provide perfect solutions for your projects. Just contact us if needed.

Different application sites have different choices for LED bay lights, which mainly depend on the illumination requirements of different places.

For example, when local lighting is needed, the led high bay often needs to be equipped with a cover or reflector with a narrow luminous angle, so as to narrow the beam and focus on the illumination.

If a large area of illumination is needed, it needs to be with a bigger beam angle cover or reflectors onto high bay LED lights.

Generally, there are 3 different covers or reflectors working with high bay lights, each reflector decides a beam angle. 60/90/120°.

But for UFO high bay LED lights, it is decided by PC Lens without any reflectors, of course, for LED UFO high bay, it is available to add reflectors on the body if needed.

You can choose the led high bay lights’ power according to the installation height. Different power consumption will be working with different heights as follows:

  • 16ft-20ft height: 100W – 120W (10000-14000 lm)
  • 25ft-30ft height: 150W (15000-18000 lm)
  • 40ft-50ft height: 180W – 200W (20000-25000 lm)

There are 2 main different types of LED high bay lights: Round UFO LED High bay and Linear high bay lights for different places as well.

The illuminance of the warehouse belongs to the lighting standard value range of the “general room or place in industrial buildings”, according to industry standards:

  • The standard value of illuminance for large warehouses is “50 Lx on a level of 1 meter”; which is equivalent to about 20 lm on the surface of 1 meter.
  • The standard value of illuminance for the general parts library is “100 Lx on a level of 1 meter”; which is equivalent to about 30 lm on the surface of 1 meter.
  • The standard value of illuminance for the semi-finished product warehouse is “150 Lx on a level of 1 meter”; which means it will be 50 lm on the surface of 1 meter.
  • The standard value of illuminance for the fine parts library is “200 Lx on a level of 1 meter” = 70 lm on the surface of 1 meter.
