Emergence’s Double-Ended linear LED replacement lamps include the industry’s first patented ‘smart switch’ which virtually eliminates shock and safety hazards during installations long associated with single-ended versions and require no changes to the tombstones reducing electrical contractor installation costs. An ASIC (Application-Specific Integrated Circuit) microchip is embedded within our proprietary power adapter that constantly monitors the lamps connection status. When the bi-pins are connected properly the switching remains locked. Otherwise, the ASIC will continue querying the connection status and deny branch power to the bi-pins to prevent any inadvertent shock hazards. Available in all sizes and color temperatures.
