What customers says

Our extensive range of high bay retrofit lamps are the ideal lighting solution for many commercial and industrial applications. LED High Bay Lamps surpass high-intensity discharge (HID) high bay fixtures in efficiency and lifespan, making them the number one choice for large, high-ceiling applications such as warehouses, gymnasiums, and high ceiling stores. Choose from 150w LED high bay lights, 175w, 250w, 400w high bay lights and 600w equivalent retrofit lights. We offer only the highest quality High Bay/Low bay LED retrofit lamps which can be installed in enclosed or open fixtures. High bay lamps such as corn bulbs have two mounting orientation options, vertical or universal, allowing them to be used as wallpack bulbs. With many big brands and various models in a range of wattagesf/lumens outputs, you are certain to find the perfect lighting solution for your project.
