LHV - Versabay® Fluorescent High Bay

The increased use of fluorescent high bays in what was traditionally HID spaces has provided an excellent means to improve lighting in the space while providing significant energy savings. The use of fluorescent lighting with electronic ballasts in unconditioned spaces has created issues regarding the reliability of the electronic components. In unconditioned or partially conditioned spaces, the temperature at the ceiling level can reach over 130ºF, thus placing the reliability of the electronic components at risk. Heat contributors such as ambient heat, ballast heat, and lamp heat can all combine to elevate the ballast above the manufacturers' maximum ballast can temperature of 90ºC. This increase in ballast operating temperature will shorten ballast life and increase maintenance.

Columbia Lighting's VersaBay® high bay was developed to address the issues of elevated temperature by creating a systems approach to properly dissipate and control the heat-producing elements; thus providing a system of long maintenance-free operation. The VersaBay® high bay, protected by ATM-Advanced Thermal Management-employs a systems approach to resolving this potential issue.
