    Lumen Output and Efficiency

    Brightness Requirements

    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

    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 Selection

    Wide vs. Narrow Beam Angles

    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.

    Matching Beam Angle to Space

    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.
