Time Delay Emergency Lights

The Time Delay Emergency Light is designed for use in industrial and commercial applications that feature HID lights throughout the facility or building. HID lights, such as Metal Halide, Mercury Vapor, or High Pressure Sodium, have a “warm-up” time when turned on, meaning they do not reach their full light power, or luminosity, for about 15 minutes. During this “warm-up”, it can be harder to see and migrate throughout the building. Emergency lights turn on immediately after AC power to a building is lost. When power returns, emergency lights normally switch off automatically.

For a facility with HID lamps, this would mean that there could be a time period where illumination levels are low and could fall below OSHA standards. The Time Delay Emergency Light eliminates this possibility by continuing to ililluminate for 15 minutes after power returns. During these 15 minutes, HID lamps with have enough time to return to full illumination levels. Time delay emergency lights are an innovative and easy way to insure the safety of occupants in facilities with HID lamps.

  • Bright and powerful 9-watt lamp heads are standard
  • Sealed lead acid battery backup with test button
  • 90-minute emergency run time
  • UL 924 Listed, meets NFPA Life Safety Code, compliant throughout North America


Time delay emergency lights are designed for use in commercial and industrial applications that feature HID lamps. The time delay feature insures that emergency lights remain ililluminated for 15 minutes after power has returned to the building.


We offer a choice between a steel housing and waterproof NEMA 4X housing.

The steel housing is suitable for most commercial applications. The 20-gauge housing is powder coated in white and is corrosion resistant. Steel emergency lights can stand up to moderate abuse.

The NEMA 4X waterproof housing is made from high-grade gray polycarbonate. This housing will stand up to adverse weather conditions and is ideal for wash down areas and industrial applications.


Utilizes 120/277v AC electricity to operate and charge the battery. Comes standard with solid state charging circuitry, low voltage disconnect, AC lockout, and brownout protection. Available in custom voltages upon request.

Nickel Cadmium Battery - The unit can come with a nickel cadmium battery. A step above the standard sealed lead acid batter, Ni-Cad batteries have a 5-7 year lifespan, are easier to replace, and decrease shipping weight.

Voltmeter - This option gives a visual display of the voltage condition/level of the battery.

Ammeter - This option gives a visual display of the current that is being consumed by the emergency light at all time.


Both the steel time delay emergency light and wet location time delay emergency light are very durable. The wet location model is waterproof and manufactured from gray fiberglass polycarbonate that is weatherproof and can be used in industrial applications.


The steel emergency light with time delay features a baked enamel white powder coat that will not chip or corrode. The wet location emergency light with time delay features a gray finish and is appealing because of its unique time delay feature that is included standard.


Time delay emergency lights offer a unique value, they provide powerful emergency lighting and general lighting for the first 15 minutes after AC power returns to the building or facility that they are installed into.
