What does Hi-temp HighBay Light mean?

“Hi-temp HighBay Light” refers to a type of industrial lighting designed for use in environments with high ceilings and high temperatures. Here’s a breakdown of the term:

  1. Hi-temp (High Temperature): This indicates that the light fixture is designed to operate efficiently in environments with elevated temperatures. These lights are built to withstand heat without degrading in performance or lifespan.
  2. HighBay: This refers to lighting fixtures intended for use in spaces with high ceilings, typically 20 feet (6 meters) or higher. HighBay lights are often used in warehouses, factories, gymnasiums, and other large open spaces.
  3. Light: This simply refers to the illumination device or fixture itself.

So, a Hi-temp HighBay Light is a lighting fixture specifically designed for use in high-ceilinged, high-temperature environments, providing efficient and durable lighting solutions in challenging conditions.

How high should a Hi-temp HighBay Light be?

A Hi-temp HighBay Light is typically used in environments with high ceilings. The recommended mounting height for HighBay lights generally ranges from 15 to 40 feet (4.5 to 12 meters). The specific height depends on factors such as the type of activity taking place, the desired light levels, and the beam angle of the light fixture. Here are some general guidelines:

  1. 15 to 20 feet (4.5 to 6 meters): Suitable for lower ceiling industrial areas, small warehouses, and retail spaces.
  2. 20 to 30 feet (6 to 9 meters): Common in large warehouses, manufacturing facilities, and gymnasiums.
  3. 30 to 40 feet (9 to 12 meters): Ideal for very large industrial spaces, aircraft hangars, and distribution centers.

The Hi-temp aspect means the fixture is built to withstand high temperatures, making it suitable for areas such as foundries, steel mills, and other industrial environments where both high ceilings and high temperatures are present.

How far should Hi-temp HighBay Light be?

The mounting height of Hi-temp HighBay lights depends on several factors, including the wattage of the light, the ceiling height, the area to be illuminated, and the required illumination level (measured in foot-candles or lux).

Here are some general guidelines for mounting heights:

  1. Low Bay (12-20 feet):
    • 100W to 150W: Ideal for mounting heights of 12 to 20 feet.
  2. Mid Bay (20-30 feet):
    • 150W to 250W: Suitable for mounting heights of 20 to 30 feet.
  3. High Bay (30-40+ feet):
    • 250W to 400W+: Best for mounting heights of 30 feet or higher.

Specific recommendations might vary based on the design and intended use of the lighting system. To ensure optimal lighting conditions, it is essential to conduct a lighting layout calculation or consult with a lighting professional who can provide advice tailored to your specific space and requirements.

What is the difference between floodlight and Hi-temp HighBay Light?

Floodlights and Hi-temp HighBay Lights are both types of lighting fixtures, but they are designed for different purposes and environments. Here are the main differences:


  1. Purpose:
    • Floodlights are designed to illuminate large areas with a broad beam spread.
    • They are commonly used for outdoor applications such as stadiums, building exteriors, and parking lots.
  2. Beam Angle:
    • Floodlights typically have a wide beam angle, ranging from 45 to 120 degrees, to cover large areas.
  3. Mounting:
    • They are often mounted on poles, walls, or other elevated structures to provide widespread illumination.
  4. Environment:
    • Floodlights are built to withstand outdoor conditions, including rain, wind, and temperature fluctuations.
  5. Typical Features:
    • May include motion sensors, dusk-to-dawn sensors, and adjustable heads for directional lighting.

Hi-temp HighBay Lights:

  1. Purpose:
    • Hi-temp HighBay Lights are designed specifically for high-ceiling industrial and commercial spaces, such as warehouses, factories, and gymnasiums.
    • The “hi-temp” variant indicates that these lights can operate in environments with high ambient temperatures.
  2. Beam Angle:
    • HighBay Lights typically have a narrower beam angle, ranging from 60 to 90 degrees, to focus light downward from high ceilings.
  3. Mounting:
    • They are usually suspended from the ceiling or mounted directly to the ceiling to provide focused, intense illumination from above.
  4. Environment:
    • Hi-temp HighBay Lights are built to handle high temperatures, dust, and sometimes even moisture, depending on the specific model.
  5. Typical Features:
    • They often have advanced thermal management systems to dissipate heat effectively.
    • Designed to be energy-efficient while providing high luminous output.


  • Floodlights are used for broad, outdoor lighting applications with wide beam angles, whereas Hi-temp HighBay Lights are used for high-ceiling indoor spaces requiring focused, intense illumination and are designed to withstand high temperatures.
