Choosing the right 4 ft linear led high bay lights needs careful thought. You should check how bright the lights are by looking at lumens. The beam angle tells you how much area the light covers. Think about how high you will mount the lights. Pick lights made from strong materials with high IP ratings. Energy efficiency is also important when choosing led high bay lights. New led technology makes these lights last longer and saves energy. These lights work well in many high bay places. Guangdong Liyinled Lighting Co.,Ltd sells trusted led high bay lights. Some examples are LY-XTD-2007, LY-XTD-2008A2 B2, and LY-XTD-2008A1 B1. Every space is different, so people should pick led high bay lights that fit their lighting needs.
Check the lumen output. This helps you know if the lights are bright enough. Make sure they fit your ceiling height and space.
Pick the right beam angle. This helps the light spread well in your area.

Think about the fixture type and mounting options. This makes installation easy. It also helps the lights last longer.
Look for high CRI ratings. This makes colors look better. It also helps you see clearly in work areas.

How tall the ceiling is matters a lot. If the ceiling is high, you need brighter led lights. For example, a 25-foot ceiling needs a 30,000-lumen led fixture. A 35-foot ceiling needs a 40,000-lumen led light. If the ceiling is 33 feet, a 33,000-lumen led light works best.
The beam angle changes how the light spreads. Look at the table to see how beam angles work in different places:
Beam Angle | Application Area | Impact on Performance |
|---|---|---|
30° | Above tall racks | Focused light keeps most light off the ceiling |
60° | General aisle lighting | Makes aisles bright and even |
90° | Loading zones | Helps shelves get more light |
120° | Open areas | Covers a wide space with light |
P25 | Narrow aisles | Cuts down shadows and glare |

Picking the right fixture is very important. There are two main types: linear and UFO high bay lights. Each type is good for different places and has special features.
Feature | UFO High Bay Lights | Linear High Bay Lights |
|---|---|---|
Lumen Output & Efficacy | Higher wattage (100W-300W), up to 45,000 lumens, ideal for 25ft+ ceilings | 60W-200W, up to 28,000 lumens, ideal for 15-25ft ceilings |
Heat Dissipation | Excellent due to radial heat sinks, lifespan of 50,000-100,000 hours | Effective but requires proper spacing to avoid heat buildup |
Glare Control | Can produce glare, newer designs include frosted optics | Often includes diffused lenses to reduce glare |
Ideal Applications | Open industrial spaces, gymnasiums, large warehouses | Narrow aisles, retail stockrooms, cold storage facilities |
Linear high bay lights spread light evenly in long aisles. UFO high bay lights work best in open rooms with tall ceilings. Linear fixtures like LY-XTD-2007, LY-XTD-2008A2 B2, and LY-XTD-2008A1 B1 from Guangdong Liyinled Lighting Co.,Ltd can be used in many places.
Tip: Linear bay fixtures often have diffused lenses. These help cut down glare and make work areas more comfortable.
Mounting options change how easy it is to put up and take care of led high bay lights. The main ways are hanging installation, 3/4 NPT installation, and pendant installation.
Installation Method | Description | Steps |
|---|---|---|
Hanging Installation | Suspend the light using a chain | 1. Disconnect power supply 2. Wiring 3. Hook up the chain 4. Affix the chain onto the rail |
3/4 NPT Installation | Use U-shaped brackets and steel pipe | 1. Disconnect power supply 2. Install brackets onto the steel pipe |
Pendant Installation | Similar to 3/4 NPT but requires two U-shaped brackets | 1. Disconnect power supply |
Hanging installation lets you change the height of the light. 3/4 NPT and pendant installations keep the light fixed in place. The LY-XTD-2007, LY-XTD-2008A2 B2, and LY-XTD-2008A1 B1 models work with all these mounting ways. This makes them good for many led bay projects.
Note: Good mounting keeps the led high bay lighting safe. It also helps the system last a long time.
You need the right lumen output for 4 ft linear LED high bay lights. This makes sure every space is bright enough. Big warehouses need strong lights to cover large areas. The table below shows how much power and brightness some high bay lights have:
Wattage | Lumen Output |
|---|---|
165W | N/A |
200W | N/A |
225W | N/A |
320W | 48,000 LM |
A high lumen output helps people see well and stay safe. Most experts say you should get at least 130 lumens per watt. This means the lights use less energy but still shine bright. Guangdong Liyinled Lighting Co.,Ltd uses constant current technology in their LED Linear Light series. This keeps the light bright and steady. Their factory has advanced machines to make good quality lights that meet these rules.
Wattage and efficacy are important for high bay lights. Lights with higher wattage, like 100W, 150W, or 200W, can make your electric bill go up. Lower wattage lights can save money and still give enough light. Efficacy means how well a light turns power into brightness. The best high bay LED fixtures can reach 130-150 lumens per watt. This is almost three times better than old lights.
High efficacy means you pay less for energy and get less heat.
Energy efficiency gets better with new technology, like the constant current system from LIYINLED.
Picking lights with high efficiency helps companies save money in the long run.

Beam angle choice is important for lighting a space. A narrow beam angle, 15 degrees or less, shines light on a small spot. This works well for jobs that need focused light, like lighting a display or a work area. A wide beam angle, 60 degrees or more, spreads light over a bigger space. This is good for lighting large rooms, offices, or lobbies. Picking the right beam angle changes how bright the room feels and how people use it.
The table below shows how wide and narrow beam angles are different for 4 ft linear LED high bay lights:
Beam Angle Type | Wide Beam Angle | Narrow Beam Angle |
|---|---|---|
Light Distribution | Broad, uniform coverage | Focused, directional output |
Primary Lighting Goal | Overall area illumination | Targeted aisle or zone lighting |
Typical Applications | Warehouses, production lines | Aisles, corridors, rack systems |
Spacing Flexibility | Wider spacing possible | More controlled spacing |
Light Control | Lower directionality | High precision control |
Tip: Wide beam angles light up big spaces with fewer lights. Narrow beam angles help light up certain spots with more control.
The best beam angle depends on the room and ceiling height. High ceilings need a different beam angle than low ceilings. For a ceiling that is 2.5 meters tall, a 60° beam angle gives good light and balance. If the ceiling is 4 meters or higher, a 30° beam angle keeps the light from spreading too much and makes the area bright.
For homes, a medium beam angle (40° to 60°) is best.
Big rooms like living rooms need a wide beam angle (over 60°) for enough light.
Small places, like stairways or closets, do better with a narrow angle (about 25°).
Knowing the ceiling height helps beam angles overlap so there are no bright or dark spots.
Standard ceiling heights around 8.86 feet need a wide beam angle of 60° or more. High ceilings need narrow angles, less than 45°.
Picking the right beam angle makes sure the space is comfortable and works well. Guangdong Liyinled Lighting Co.,Ltd uses new technology in their factory to make good LED linear lights. Their products, like LY-XTD-2007 and LY-XTD-2008A2 B2, have both wide and narrow beam angle choices. For more information, check out the LED Linear Light series on their website.
Energy efficiency is important when picking 4 ft linear LED high bay lights. Certifications help buyers know which lights use less energy and save money. The Energy Star label shows a light follows strict rules from the EPA and U.S. Department of Energy. DLC certification proves the lights work well and can get rebates from utility companies.
Certification | Importance |
|---|---|
Energy Star | Makes sure the light follows tough energy rules from the EPA and U.S. Department of Energy. |
DLC | Shows the light works well and is needed for rebate programs. |

Color temperature changes how a room looks and feels. In factories and warehouses, picking the right color temperature helps people see better. Experts say 4 ft linear LED high bay lights should have color temperatures from 1800K to 2200K. This range works well in hot places because it lets light shine through better and cuts down blue light scattering. Lower color temperatures help workers see clearly in dusty or steamy spots.
1800K to 2200K is best for factories and warehouses.
It helps people see better in dusty or steamy rooms.
