The 8W emergency driver EMS8W27 is a compact battery-backup power module designed to provide reliable emergency illumination for LED fixtures such as 4ft vapor-tight luminaires and 4-foot linear strip lights. It operates across a wide universal input voltage range from 100 to 347 volts AC, making it compatible with most commercial and industrial electrical systems.

When a power outage occurs, the driver instantly switches the connected LED fixture into emergency mode and supplies a constant output of approximately 8 watts of emergency power, allowing the light fixture to remain illuminated for a minimum of 90 minutes.

These drivers typically include a test switch and LED indicator light for system diagnostics, allowing maintenance personnel to verify battery status and perform required periodic testing. The system normally requires approximately 24 hours for a full battery recharge after installation or after a discharge event.

Because of its constant-power output design, the emergency driver ensures stable light output even as the battery voltage decreases during discharge, helping maintain visibility along emergency exit routes. Overall, the EMS8W27 8W emergency driver provides a cost-effective and code-compliant solution for converting standard LED vapor-tight fixtures, 4-ft linear strip lights and 4ft wrap lights into emergency-ready lighting systems, ensuring occupant safety and illumination continuity during unexpected power failures in commercial and industrial facilities.
