How to choose the right LED high bay for your industrial lighting?

High-bay lighting features a deep reflector used to direct the light down from a high ceiling. High bay fixtures also produce a diffused light, which helps to reduce glare.

Whenever a large indoor space has a ceiling higher than 15-20 feet such as factories, warehouses, department stores, indoor car parks, sports halls/ gymnasiums, and community centers, high bay lighting is usually the best solution. These facilities are typically vast and cover a lot of vertical as well as horizontal space, requiring powerful lighting to provide the appropriate foot-candle levels to adequately illuminate.

Below are some important points should be taken into consideration when purchasing LED high bay.

1. Luminous efficacy(Lumen/Watt)

Lumen is the unit of luminous flux and indicates the total amount of light emitted by the light source. Wattage indicates the amount of energy consumption of a lamp. The higher luminous efficacy, the more energy saved.

Today, most LED high bay can achieve 130-150lm/watt, GaoTerLED can do up to 190lm/watt.

2. Lux levels

Lux is the SI unit of illuminance, equal to one lumen per square meter. For most industrial facilities, 200-300lux is acceptable.

3. Lumens (total lumen output)

The higher the lumens rating the “brighter” the lamp will appear. Keep same watt, the higher lumens, the better.

4. Beam Angle

Beam Angle means how wide or how bright the area of illumination can be. The lower the ceiling, the wider the beam angle need be. GaoTerLED high bay offers 60°, 90°, 120°.

5. Kelvin

Kelvin is used in lighting to measure the color temperature of a luminaire. Typically, Kelvin temperatures for industrial lighting applications fall somewhere on a scale from 4000K to 6000K.

Special applications

** Food processing&beverage industry

In harsh environments like food&beverage processing factories, Pharma plants, garden centers, slaughterhouse, cold storage and bakery, does the normal high bay work ?

The answer could be No. The so called ” food processing high bay”  without glass&exposed screws is a wise choice, which can meet requirements of NSF for food processing applications. Featuring with its waterproof IP69K structure, you can have it hosed down by a water gun.

** High temperature working environment

When comes to extremely high temperature environment,  such as steel mills, you need a lighting solution to withstand the heat of its facilities. This could be a big challenge for LEDs and the driver. High temperature testing ( 65°C ) is required before you placing the order.
