Flexible, Efficient Replacement LED Lighting

I-BEAM® LED High Bay Luminaire

The I-BEAM® LED high bay luminaire by Lithonia Lighting® offers the high-quality illumination, longer life and energy savings expected of LEDs. Additionally, it is easy to configure with numerous options for almost every electrical and optical component, including reflectors, wire guards, emergency battery pack, occupancy sensors, surface mount brackets and more. I-BEAM LED luminaires can be integrated with factory-installed digital controls such as occupancy sensors as well as daylight photocells for increased energy savings. I-BEAM LED high bays also come fully capable of dimming down to 10 percent.

Lithonia I-BEAM LED

Available for mounting heights ranging from 15–40 feet and ambient environments up to 131°F (55°C), the I-BEAM LED high bay meets both horizontal and vertical light level requirements through narrow or wide distributions. Reflectors are precision formed and utilize premium materials including ALANOD® MIRO® specular aluminum, while an optional semi-diffuse lens provides glare control and LED protection.

Affordable for many high bay applications such as manufacturing, warehousing and other large indoor spaces, I-BEAM LED high bays provide a payback in as little as two years and an impressive return on investment over the life of the product. Additionally, conduction and natural convection technologies used in the I-BEAM LED luminaires maximize cooling, fixture performance and lumens per watt.
