How-to Spot BAD LED High Bay Lighting


How To Spot Bad LED High Bays

Estimated Read Time: 1:00

Looking to upgrade your facility to LED high bays? It’s important to know that not all LEDs are created equal. Our Crescent Electric Energy Solution Specialists outline the important factors to consider when making the switch.

Surge Protection

6kV is the ANSI industrial standard and it is the mimimum level to consider for your hight bays. Look for manufacturers like Lithonia Lighting who meet or exceed ANSI requirements.

Temperature Performance

Make sure the “operating temperature” on the import high bay spec sheet matches the label on the fixture. Driver life and LEDs can be compromised if used in temperatures above the actual fixture rating.

Lumen Maintenance

Beware of fixtures that provide a lumen maintenance number without explanation of their calculation or their corresponding temperature. LED performance decreases at higher temperatures. By testing at lower temperatures, some manufacturers can pad their life expectancy. Lithonia Lighting readily provides lumen maintenance for a range of temperatures, so you know how your fixutre will perform in your environment over time.

Serviceable Driver

Many import level fixtures (especially “UFO fixtures”) feature commodity-grade drivers absent of any surge protection and are not able to be serviced or replaced. Which means if you have any failure, you have to throw away the entire fixture.


Exposed LEDs and clear lenses create hot spots, high glare and poor uniformity.

Warranty and Support

You’ll want to find a manufacturer who offers the industry standard 5-year limited warranty. Some even offer 10-years depending on the model.
