Why Replace Emergency Light Bulbs Promptly?

Dead or dim bulbs compromise visibility and life safety during emergencies. NFPA 101 and OSHA require emergency egress lighting to function for at least 90 minutes during a power failure. Replacing failed bulbs immediately helps maintain compliance and occupant safety.

FAQs About Emergency Light Bulbs

What is an emergency light bulb?

It’s a specialty lamp designed for emergency lighting fixtures, providing reliable illumination during power outages to help guide occupants to safety.

How do I choose the right replacement bulb?

Match the voltage (6V, 12V, or 24V), wattage, and base type—like bi-pin, wedge, MR16, or PAR36. This info is usually printed on the fixture label or your existing bulb.

Can I upgrade halogen emergency lights to LED?

Yes. Many LED retrofit bulbs are designed to replace halogen or incandescent lamps. Just verify voltage and base compatibility before installing.

Do emergency bulbs come in different beam styles?

They do. Some provide a flood beam for general coverage, while others—like MR16 or PAR36 sealed beam lamps—offer focused, directional lighting for remote heads.

Are emergency light bulbs universal?

No. You must choose a bulb that matches your fixture’s electrical specs and physical base type. There is no one-size-fits-all emergency bulb.

How long do emergency light bulbs last?

LED emergency bulbs can last up to 50,000 hours, while halogen and incandescent models typically last between 1,000–3,000 hours.

Can I use any bulb in outdoor emergency lights?

No. For outdoor use, choose sealed or weather-rated lamps like PAR36 sealed beam bulbs that can handle moisture, dust, and temperature extremes.

When should I replace the bulb vs the entire fixture?

If your fixture is in good shape and the replacement bulb specs match, swapping the bulb is sufficient. But if it’s cracked, discolored, or not charging, consider upgrading to a new emergency light fixture.

Does mounting type affect replacement or upgrade options?

Yes. When replacing bulbs in a wall-mounted or ceiling-mounted emergency light, make sure the lamp fits the housing and beam spread needs. For full upgrades, browse wall-mounted exit signs or ceiling-mount exit signs.
