LED high bay lighting is usually used in a large space that needs to be illumiated, especially for where there are high ceilings. The wide applicability makes high bay lights the ideal luminaire for most indoor scenes, eg, industrial places, factories, workshops, warehouses, gymnasiums, supermarkets, toll stations, and most high ceiling applications.
Along with the lighting technology development, there are several different lighting technologies used in high bay lights, including Compact Fluorescent (CFL), High-Intensity Discharge Lamps (HID) developed in 1940s, Metal Halide lamps (MH) developed in 1960s, and Light Emitting Diode (LED) developed in 1960s. In this article we will talk about how to choose Led high bay lights.
Among all the lighting sources, LED stand out from the competition. Being deemed as the 4th generation lighting sources, LED lights started commercial use since 1990s, and become popular since 2000s. Now, LED High bay light is dominating the industrial and indoor high ceiling lighting solutions.
Comparing with HID and MH lights, LED stands out on many aspects:
Now, when there are new constructions or building renewal, people will be hesitate to choose LED Lightings. However, facing with many choices on LED High Bay Lights and different prices, users will always be confused on which one to choose and what are the factors that decide LED High Bay Lights price.
Yaham Lighting has been in LED Industry and manufacture LED products since 2002. And here are some comments from our engineers:

Raw materials |
Raw materials are the main factor that decide product quality and costs. The most important raw materials of LED High Bay lights including: LED chips, LED Driver, Heat Sink, and Cables. The raw materials prices vary from incredible low to quite high, and so does the luminaire. |
LED High Bay lights price is positively correlated with raw materials price. |
Yaham Lighting products adopt first-rate quality raw materials, ensure superb quality. Eg, Nichia chips, Meanwell, Inventroncis and Yaham driver, private mold heat sinks, etc. |
Product Quality |
Good quality usually represents cost efficient, better performance, and less maintenance costs. Thus, it’s a good investment to high grade life and to better future. |

Contact with Yahan Lighting, let’s show you what good service should be. |
Sales Channels |
LED High Bay Lights usually go through quite many channels before they are delivered to final users. The more channels they go through, the more higher the price. |

Yaham tries to shorten the Sales Channels by cooperated with large distributors and contractors. |
Brand Premium |
Consumers are likely to pay more for world famous Brands. So leading brands tends to sale with more profits, eg, Apple and Samsung in Handphone industry. |

The factors affecting the number of highbay lights in industrial lighting rooms are:
1. Locations. Common applications for highbay lights include warehouses, workshops, exhibition halls, etc. Different application requires different brightness.
2. Lamp Power and luminous flux of highbay lights
3. Space utilization coefficient and maintenance coefficient
Generally, the following formula can be used for rough calculation: Average illuminance (Eav) = single luminaire flux Φ × number of luminaires (N) × space utilization factor (CU) × maintenance factor (K) ÷ floor area (length × width).
Power density selection: The recommended power density for traditional MH/HID lamps is about 10-30 watts / square meter, and for led lighting, 3-12watts / square meter would be ideal. For general office lighting by LED, 3-7 watts / square meter would achieve more than 300lx on floor. And for hotel shopping malls, where requires higher brightness of more than 500lx, it can be designed to 5-12 watts/square meter.
Here is an example. A machining workshop has a dimension of 60m length, 30m width and 8m height, and with a work-plane height of 0.8m. The ceiling is cement soil structure and the walls are painted white. By prudent consideration, the owners decide to have the work-plane 400lx to achieve great visibility and enhanced worker safety, how many high bays they should have then?
Take 150W LED high bay for example, with 160lm/W efficacy, it delivers 24,000lm. The Coefficient of Utilization (CU) is by default 0.7, and maintenance factor (K) as 0.8. Take all data into the simple formula EAV=( Φ×N×CU×K)/(A×B), that is 400=24,000*N*0.7*0.8/(60*30), so the Q’ty of LED Highbay should be N=54pcs.
So we can know roughly that for a 1,800 Square meter factory, 54pcs 150W LED High Bay Light of 160lm/W would work well. And to know for sure the lighting effects, we’d better run a simulation by professional lighting designers on computer.
Many agents around the world and customers who need to purchase LED high bay lights will face a difficult problem when they come to China to choose a supply factory, that is, how to choose a reliable factory. As an industry leading manufacturer of LED high bay light, Yaham Lighting advice you to consider the following factors.
The establishment time is a fact that a LED High Bay Light factory cannot change, and it is also a witness of a company's manufacturing experience in the industry. The establishment of factories in China is generally not long. Therefore, the establishment of a LED high bay light factory can reflect its reliability.
China is a populous country and is also known as the "world factory." However, the quality of LED high bay lights produced by many small factories is always poor. When Choosing a manufacture, it’s important to check the number of its employees. This provides a lot of protection for the lighting products we produce.
If you know that a factory is well known in the manufacturing industry, or has a lot of visibility in LED high bay light manufacturing, then it may be your better choice. However, you must be very familiar with LED High Bay Light Industry to choose a more well-known factory.
If it is difficult to source the manufacturer information from the outside, the product supply case will be an important way to understand the reliability of the factory. Because there are a lot of demanders similar to yours, the factory has already been carefully evaluated. So you can choose this factory without worry. The premise is that those supply cases must be true.
After-sales service is indispensable, all products may have problems. If there is no after-sales service, the value of LED lights will be greatly reduced accordingly. Therefore, high-quality after-sales service can greatly reduce the difficulty of customers' use. After a failure, it can be quickly resolved without affecting the normal use of the customer.
