High Bay LED Lights FAQ

What Are High Bay LED Lights?

LED High Bay lights are powerful ceiling-mounted fixtures specifically engineered for large interior spaces with high ceilings-think warehouses, manufacturing facilities, gymnasiums, and aircraft hangars. These fixtures are designed to perform optimally when mounted at 20 feet or higher, where they can effectively illuminate vast areas while maintaining proper light distribution.

What are the Different Types of LED High Bay Lights?

The two primary styles in the market: UFO and Linear fixtures. UFO high bays feature a compact, round design that makes them excellent direct replacements for traditional metal halide fixtures. Linear high bays, on the other hand, have a rectangular form factor that perfectly matches the aesthetic of fluorescent high bay systems. We've found that customers often choose based on their existing infrastructure and aesthetic preferences.

How Do High Bay LEDs Compare to Metal Halide?

LED high bays consume significantly less energy while delivering superior performance. Unlike metal halide fixtures that require warm-up time, LEDs provide instant full brightness. They also last substantially longer, which dramatically reduces maintenance costs-a factor that becomes increasingly important in high-ceiling applications where accessing fixtures can be challenging and expensive.

What Beam Angle is Best for High Bays?

Beam angle selection depends on your specific ceiling height and coverage requirements. For lower ceilings (20-25 feet), wider beam angles distribute light more evenly across the space. However, for taller installations (30+ feet), narrower beam angles help focus the light downward more effectively, preventing light loss and ensuring adequate illumination at floor level. It's been our experience that purchasing high bays with the wrong beam angle is one of the biggest mistakes made in replacing metal halide and fluorescent fixtures with LED.

How Much Energy Can You Save with Energy-Saving High Bay Lighting?

The energy savings are substantial. Most facilities see approximately 50% reduction in energy consumption when upgrading from metal halide or fluorescent systems. When you incorporate motion sensors, which we highly recommend for areas with intermittent activity, energy savings can reach up to 90% in less frequently used zones.

What Is the Coverage Area for High Bay Lights?

Coverage area varies based on several factors: fixture wattage, lumen output, beam angle, and mounting height. Rather than providing generic coverage estimates, we've learned that the most effective approach is to provide a custom lighting plan for each space. Our Product Specialists provide complimentary lighting plans before purchase to ensure your specific requirements are met and you achieve optimal coverage.

Are LED High Bay Lights Waterproof?

This depends on the specific fixture design. Our UFO LED fixtures feature IP65 or higher ratings, making them suitable for environments with moisture exposure. However, our linear fixtures aren't IP-rated and should be used only in dry locations. Always verify the IP rating matches your environmental requirements before installation.

What Is the Typical Lifespan of High Bay LED Lights?

Our high bay fixtures are rated for 50,000+ hours of operation. To put this in perspective: if you operate your lighting 12 hours daily, 365 days per year, you're looking at over 11 years of reliable service. This longevity is particularly valuable in high-ceiling applications where fixture access for maintenance can be costly and disruptive.

What's the Recommended Mounting Height for a High Bay fixture?

These fixtures perform optimally at 20 feet or higher. For exceptionally high ceilings (over 30 feet), you may need higher-wattage fixtures or tighter beam angles (60-90 degrees) to ensure adequate light reaches the working level. We often help customers determine the ideal configuration based on their specific ceiling height and application requirements.

What Type of LED Is the Best Replacement for a Metal Halide High Bay?

UFO LED fixtures provide the most seamless one-for-one replacement for metal halide systems. They can effectively replace any metal halide wattage from 250W to 2000W while delivering energy savings of 50% or greater. The compact design also makes installation straightforward using existing mounting hardware.

What Type of LED Is the Best Replacement for a Fluorescent T5 / T8 High Bay?

Linear LED high bays are the natural choice for fluorescent T5/T8 replacements. Their rectangular profile matches the aesthetic of fluorescent systems while eliminating common fluorescent issues like flickering, humming, and frequent bulb replacements. The upgrade is typically straightforward and doesn't require ballast modifications.

What Types of Controls are Commonly Used on LED High Bays?

Motion sensors are the most popular control option we see customers implementing. These sensors automatically bring fixtures to full power when activity is detected and dim them during periods of inactivity. This approach maximizes energy savings while ensuring lights are always available when needed. Also, dimming and brightening the lights through repeated cycles does not shorten the lifespan of our LED fixtures.

What are Wattage Adjustable and Color Adjustable LED High Bay Lights?

These fixtures feature onboard toggle switches that allow you to select both light output levels and color temperature after installation. This flexibility eliminates the guesswork in specification and provides adaptability if your needs change over time. It's particularly valuable when you're uncertain about optimal settings for your specific application.

What are Commercial Grade and Industrial Grade LED High Bays?

Our high bay fixtures are built for longevity and reliability. Available in wattages from 100W to 600W, they feature oversized heat sinks, premium drivers, and LED chips operated well below maximum capacity. While this approach results in higher upfront costs due to superior materials and construction, it delivers the reliability and dependability that commercial and industrial customers require. We stand behind our products with comprehensive support and warranty coverage if any issues arise.

How Do You Wire LED High Bay Fixtures?

Most of our LED high bays come equipped with a whip/cord for flexible installation options. Customers typically either hardwire the fixtures to junction boxes or install plugs to utilize existing sockets. Either approach is straightforward for qualified electricians. We recommend consulting with a licensed electrician to determine the best installation method for your specific situation.

How Long Are the Warranties on LED Lighting Supply High Bay Lights?

All our high bay lights come with a 5-year warranty. If there is an issue, just call us, and we will get the warranty process going for you.
