Understanding the visual acuity needed for each task helps in selecting fixtures with the appropriate lumen output.

Lumens, Wattage, and Beam Angle:

  • Lumens: This measures the total amount of visible light emitted by a fixture. Higher lumen values indicate brighter light, which is essential for covering large areas or spaces with high ceilings.
  • Wattage: While lumens indicate brightness, wattage measures energy consumption. LED high bays are preferred for their ability to provide high lumens with lower wattage, enhancing energy efficiency.
  • Beam Angle: The beam angle affects how light is dispersed. Narrow beam angles suit high-ceiling environments for focusing light downwards, while wider angles work best for lower ceilings or when you need a broader light distribution.

By carefully considering these factors, facility managers can choose the right number and type of LED high bays to meet their lighting needs effectively, ensuring a well-lit, efficient, and productive environment.

Calculating Your LED High Bay Needs

Calculating the optimal number of LED high bays required for a space involves a few critical steps that take into account the area’s dimensions, desired brightness levels, and the specific characteristics of the LED fixtures.

Here’s a step-by-step guide to help you determine your LED high bay needs:

  • Determine the Area’s Square Footage: Calculate the total area to be illuminated by multiplying the length and width of the space (in feet). For example, a warehouse measuring 100 feet by 150 feet has an area of 15,000 square feet.
  • Establish the Desired Brightness Level: Brightness is measured in lumens per square foot (lux or foot-candles). Different activities require different levels of brightness. For instance, general warehousing may need about 20-30 lumens per square foot, while detailed assembly work might require 50-75 lumens per square foot.
  • Calculate Total Lumens Needed: Multiply the area’s square footage by the desired brightness level to get the total lumens required. Using the warehouse example and aiming for 30 lumens per square foot, you would need 450,000 lumens (15,000 sq ft * 30 lumens/sq ft).
  • Understand Your LED High Bays’ Specifications: Check the lumen output of the LED high bay lights you’re considering. For instance, if each fixture outputs 15,000 lumens, you’ll need to determine how many fixtures are required to meet your total lumens need.
  • Calculate the Number of Fixtures Needed: Divide the total lumens required by the lumen output of a single fixture. In the warehouse example, you would need 30 fixtures (450,000 total lumens / 15,000 lumens per fixture).

Example for an Industrial Facility:

For an industrial facility requiring a higher brightness level of 50 lumens per square foot over an area of 10,000 square feet, the total lumens needed would be 500,000. If using LED high bays with a lumen output of 20,000 each, the facility would need 25 fixtures (500,000 / 20,000).

This step-by-step guide provides a basic framework for calculating your LED high bay needs. Remember, factors like fixture placement, ceiling height, and the presence of obstacles can also influence the number of lights required, so it’s beneficial to consult with a lighting professional for a tailored solution.

Maximizing Light Coverage and Uniformity

Uniform light distribution with LED high bays creates a well-lit and safe environment by evenly spreading light, eliminating dark spots, and reducing glare to prevent eye strain and accidents. Here are strategies to ensure maximum light coverage and uniformity:

  1. Strategic Fixture Placement: Uniform lighting comes from strategically placing LED high bay fixtures to overlap beams, filling shadows for consistent illumination. Use a lighting layout plan, made with design software or by a lighting designer, to find the best spots for each fixture according to the area’s specific dimensions and features.
  2. Appropriate Spacing Between Fixtures: Correct spacing of LED high bays is key for even light. Spacing should consider ceiling height and fixture beam angle: closer spacing for higher ceilings and narrow angles, wider for lower ceilings and broad angles. This ensures uniform lighting without overly bright or dim spots.
  3. Selecting the Right Beam Angle: The beam angle of an LED high bay light determines how widely the light is dispersed. Choosing the correct beam angle for your space’s ceiling height and layout is essential for uniform distribution. Wide beam angles usually work better for lower ceilings and spaces needing broad light coverage, whereas narrow beam angles fit higher ceilings or areas where you want to focus the light.
  4. Utilizing Reflective Surfaces: Making use of the natural reflectivity of walls, floors, and ceilings can also enhance light distribution. Light-colored and reflective surfaces can help bounce light around the space, contributing to a more uniform lighting environment.

By strategically placing fixtures, adjusting spacing, selecting the right beam angle, and using reflective surfaces, you can maximize light coverage and uniformity with LED high bays. This enhances safety, visual comfort, and energy efficiency by effectively using light where needed.
