The T-Bar LED Smartlight Seismic from JLC-Tech not only is compatible with traditional suspended ceilings but also can be integrated into the suspension system. The lighting fixture replaces 2’ or 4’ standard grid cross tees and eliminates special seismic mounting requirements and the need for independent support cables. The system uses less wattage than traditional CFLs and facilitates the use of direct-current energy generated on-site by alternate energy sources. armstrong.com
