How to choose the right beam angle for LED high bay light
Choosing the right LED light beam angle is very important for any lighting project. Imagine walking into a dimly lit building, how do you feel about it? You may never want to go there again! One reason this happens is that the light beam angle is wrong.
Today, LED will share with you how to choose the right beam angle of LED high bay light
What is the beam angle of the LED high bay light?
The beam angle is the angle at which the LED light spreads on the floor when it is turned on. It can also be called beam spread. Choosing the right type of beam angle can give your building the right ambience and visibility. The image below shows how the beam angle looks like.
When choosing the beam angle of the LED high bay light, the most basic consideration is to ensure that the space you want to light can be illuminated. In fact, for any lighting purpose, we need to consider a few factors.
Beam Angle Considerations
1. Building type
The type of building is one of the factors that determines which LED light beam angle to choose. Because you need to consider how much lighting you need in your building. Then you can choose the correct beam angle. Because depending on the height of the ceiling, the beam angle affects lighting and visibility. For example, warehouses with high ceilings require LED high bay lights with different beam angles than retail stores.
2. The number of LED high bay lights
If you have a 50,000 square foot building, how many lumens will provide the right amount of light? According to industry standards, for a commercial space, we need 70 lumens per square foot. As a lighting designer, for any lighting project, you need to make sure you have a lighting layout design before choosing the beam angle of your LED high bay.
After that, now you can calculate how many fixtures you need.
Start by multiplying the square footage of the building by the industry standard to get the total lumens.
50,000 (L x W) x 70 lumens = 3,500,000 lumens (total lumens)
Then multiply the total lumens by the constant 1.40. This number is calculated by adding together the light loss factor (.75) and the utilization factor (.65). You need to take this into account when calculating total lumens for a specific space.
1.40 x 3,500,000 (total lumens) = 4,900,000 lumens (lumen loss)
After Z, you need to add total lumens and extra lumens together. This will show you the total amount of lumens needed to illuminate the lighting space.
3,500,000 (total lumens) + 4,900,000 (lumen loss) = 8,400,000 lumens
3. Height of ceiling and lamps
Check the ceiling height to make sure the beam angles overlap. If not, you may end up with a dark, dim area in the building. The overlapping beam angles will ensure the light completely covers your space and prevent injury.
Standard ceiling heights are approximately 7.9 to 8.9 feet. Therefore, a larger beam angle (60 degrees or more) should suffice. If your ceiling height is more than 8.9 feet, you will need a narrow beam angle of less than 45 degrees.
In any lighting situation, you will need to adapt to the height of the ceiling to ensure you have a bright workspace. When you use LED high bay lights in industrial areas, you can use high bay lights with reflectors, which can better spread the light.
4. LED mining bulb type
Depending on the application, you need to choose different types of LED bulbs. In industrial spaces with high ceilings, the higher the fixture, the narrower the beam angle you need. For lower ceilings, the beam angle will be wider. If you are using a LED high bay light with a 360 beam angle, you may consider using a reflector to reflect the light.
Beam angle of different LED high bay light bulbs:
· LED flood light: 120°-150°
· LED spotlight: 15°-90°
· LED downlight: 120°-160°
· LED high bay light: 60°-120°
· LED corn light: 180°-360°
· LED downlight: 30°-60°
