Emergency LED Light Kit

The Hubbell Incorporated EV4DB is a dual-head emergency lighting unit designed for indoor safety compliance. It operates on 120/277V input power and uses LED lamp heads to provide illumination during power failures. The kit includes a nickel-metal hydride battery rated for 90 minutes of emergency operation.

Suited for Code-Compliant Interiors

This unit fits commercial corridors, stairwells and utility rooms requiring battery-backed egress lighting. The plastic housing mounts to standard junction boxes and the two adjustable heads cover required paths of travel. Facilities needing longer run times, higher lumen output or wet-location ratings should consider other fixtures.

90-Minute Emergency Duration

The integrated battery delivers a full 90 minutes of illumination at 4.0 W total load, meeting common life-safety code minimums. Output voltage is 1.2 V DC to the LED heads. If local regulations demand a longer duration or a different voltage, this model will not satisfy the requirement.

Questions about this item

How do I mount the EV4DB kit and wire it for 120/277 V, and what step is often missed?

Secure the plastic housing to a junction box, connect the 120 V or 277 V supply to the driver leads, then attach the two LED heads; the step often missed is tightening the strain-relief clamp so the cable cannot pull loose.

What maintenance will the nickel-metal hydride battery need and when should I replace it?

The NiMH pack is maintenance-free but loses capacity over time; plan to replace the battery when the 90 min emergency run time drops below code requirements, typically after several years of service.

What limits continuous operation during a prolonged power outage?

The 4.0 W LED load draws the 1.2 V DC battery until the 90 min rated duration ends; after that the output voltage falls and illumination stops until mains power returns.
