What are high bay lights?
High bay lights make the process of illuminating large indoor spaces more efficient and easier than ever. They're ideal for indoor spaces with high ceilings (typically 15-50 feet). Usually when it comes to higher ceiling applications, there is more space that needs light, so it's very important that these fixtures are capable of providing bright and powerful light to large areas.
What are the different types of high bay lights?
There are numerous types of fixtures available when it comes to high bay lights. These include LED lights, metal halide (HID) lights, induction lights, and fluorescent lights. For example, LED lights offer extremely long life and energy efficiency. However, they typically require a larger initial investment up-front. Traditional HID and fluorescent lights are less expensive initially, they don't last as long (requiring constant maintenance) and require more energy to operate.
Aside from the various costs and efficiencies, there are also several different types of high bay LED lights available. They include round (UFO) high bays, linear high bays, architectural high bays and grid mount high bays, with all offering their own unique light qualities and coverage styles. Selecting the type of light that would be best for you really depends on your personal tastes and what tasks you'll be performing in the area they're installed in.
Where are high bay lights used?
Generally, high bay lights are commonly used in commercial and industrial settings. They often can be seen in large recreational facilities, storage warehouses and manufacturing and assembly plants.
How many high bay lights do I need?
Determining how many high bay lights you need comes down to two important factors, are they for a retrofit installation or for a new installation.
When it comes to a retrofit installation, you need to take note of what type and how many fixtures you currently have installed. Since LED lights require less energy to deliver the same kind of light output as HID, or metal halide, chances are you do not want to base your decision on wattage. For example, a 400-watt high bay with LED technology produces the same light output as a traditional 1000-watt high bay with HID technology. So if you have 10 - 1000-watt HID high bays in your space, you would want to replace them with 10 - 400-watt LED high bays to ensure you have the same amount of light as before.
Now, if you are working on a new installation project its a little bit different. For instance, if you're going with high bay lights with LED technology then you would look at the lumen output they produce. Here are some examples:
- 20-29 feet you will need a high bay light that produces 20,000 to 29,000 lumens
- 30-39 feet you will need a high bay light that produces 30,000 to 39,000 lumens
- 40-49 feet you will need a high bay light that produces 40,000 to 49,000 lumens
The correct spacing of high bay lights is an important factor in determining how the light output will be dispersed throughout an area. Below are some examples of some spacing options to get the best light output for your space:
- At a mounting height of 20-feet, if the high bay lights are spaced every 15-feet, the light output would be bright. If you space them every 18-feet apart, the light output would be normal or adequate.
- At a mounting height of 30-feet, you can bump the spacing up to 20-feet apart and still have a bright light output. However, if your just looking for a normal light output, then 25-feet spacing would be sufficient.
