End caps are available in standard and custom finishes. The embedded controls can be installed and are used to monitor system performance, allow for a constant lumen management/compensation function, facilitate simple plug-and-play network and control upgrading via Cat-5 cabling. Full-range (0-10V) dimming is also standard. The ST Series luminaires are available in surface, stem and suspended mount configurations.
