Description

GLT's BAY-38L-UV-CCT brings unmatched flexibility to industrial and commercial high bay applications where lighting requirements change over time. This round UFO fixture features field-selectable wattage (150W/200W/240W) and switchable color temperature (4000K/5000K) through accessible dip-switches, allowing facility managers to optimize performance without stocking multiple SKU variants.

Built with die-cast aluminum construction and high-efficacy LEDs delivering up to 160lm/W, this fixture produces between 24,000 and 38,400 lumens depending on wattage selection. The patent-pending optical design maintains uniform light distribution across both CCT settings, eliminating the uneven output that plagues competing switchable fixtures.

  • Three selectable outputs: 24,000lm / 32,000lm / 38,400lm
  • Dual color temperatures (4000K/5000K) via dip-switch
  • DLC Premium certified for utility rebate eligibility
  • Replaces 400W-550W HID systems with significant energy savings
  • Durable round hanging ring for versatile mounting
  • Wide voltage range: 120-277V
  • Extreme temperature performance: -40°C to 50°C (-40°F to 122°F)
  • L70 lifespan exceeds 100,000 hours at 25°C
  • Available in black or white housing options

Perfect for automotive repair shops requiring accurate color rendering, refrigerated warehouses demanding cold-temperature reliability, and distribution centers balancing energy efficiency with operational flexibility. The switchable wattage capability lets you adapt lighting intensity as ceiling heights or space usage evolves without costly fixture replacement.

Compatible with emergency battery backup and motion sensor accessories for code compliance and enhanced energy savings. Backed by a comprehensive 5-year warranty and cETL Listed certification for North American installations.

Frequently Asked Questions

What is the recommended lumen range for LED high bay lights based on ceiling height?

For ceilings between 10-15 feet, it is recommended to use LED high bay lights with 10,000 to 15,000 lumens. For heights of 15-20 feet, lights should have 16,000 to 20,000 lumens. For much higher ceilings, around 25-35 feet, choosing lights with 33,000 lumens is ideal. Remember, the spacing between the lights also plays a crucial role in effective lighting.

How should I select the appropriate high bay LED lights for my warehouse?

When choosing high bay LED lights, consider the color temperature and the mounting height. For task lighting, a cooler color temperature between 5000K and 6500K is preferable, whereas for ambient lighting, a warmer range of 3000K to 4000K is recommended. Ensure the light's specification matches the height at which it will be mounted.

What ceiling height is appropriate for high bay lighting fixtures?

High bay lighting fixtures are suitable for ceiling heights ranging from 20 to 45 feet. In contrast, low bay fixtures are designed for lower ceiling heights of 12 to 20 feet. Choosing the correct fixture based on your ceiling height is crucial for optimal illumination.

What spacing should be used between LED high bays?

The spacing between LED high bays can vary depending on the desired brightness. For brighter illumination, a spacing of 18 to 20 feet is recommended. For normal lighting conditions, a spacing of up to 16 feet should suffice. Note that higher mounting heights may require lights with higher power.

What lighting controls are available for LED high bays?

Dimming modules, motion sensors and daylight sensors are the most popular light controls for LED high bay lights. Dimming modules enable the light level of the high bay to be manually dimmed to a lower level to save energy. Motion sensors allow automatic on function when motion is detected and off function when there is no activity. Daylight sensors automatically adjust the light level of the high bay to be higher or lower depending on detected ambient light from outside.
