Emergency Light Bulbs – Replacement Lamps for Exit and Egress Fixtures

Emergency light bulbs keep your systems compliant and ready when power fails. Whether you’re relamping a facility or swapping a single unit, we stock LED, halogen, incandescent, and sealed beam options—including replacement bulbs for Exit Signs and Emergency Lights.

From emergency light replacement to emergency exit sign replacement, our selection covers bi-pin LEDs, wedge-base lamps, MR16 halogen bulbs, PAR36 sealed beams, and retrofit kits in 6V, 12V, and 24V. Most are compatible with commercial emergency lights, exit signs, combo fixtures, and hazardous location emergency lights.

Need to replace a bulb? It might be time to upgrade. Explore Battery Backup Emergency Lights or Battery Backup Exit Signs to ensure 90-minute runtime and UL 924 compliance.

💡 Need help identifying the right emergency light bulb? Check the model number and voltage on your fixture’s nameplate. If unsure, our team can help you find a match for LED, halogen, or sealed beam units.

LED retrofit bulbs are ideal for upgrading older systems, delivering long life, directional output, and energy savings. For legacy installations using halogen or incandescent emergency bulbs, we offer direct replacements that meet original specs.

Common Emergency Bulb Types

  • LED bi-pin bulbs (T5, T6, G4, G5.3 bases)
  • MR16 halogen lamps – 6V, 12V, 24V
  • PAR36 sealed beam units – 6V/12V halogen or incandescent
  • Wedge base incandescent lamps (1395, 906, 912 models)
  • LED retrofit kits for incandescent or halogen systems

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.

Compatible Fixtures

Whether you’re retrofitting a commercial property or maintaining an existing safety system, we stock bulbs compatible with nearly every major fixture style.

Emergency Light Bulbs Spec Guide

Spec Snapshot

  • Voltage Match: Select the exact system voltage—6V / 12V / 24V DC—as shown on the fixture nameplate. Using the wrong voltage can damage drivers or reduce runtime.
  • Base & Form Factor: Match the socket: bi-pin (e.g., G4, G5.3 for MR16), wedge (906/912/1395), MR16 2-pin, or PAR36 sealed beam (screw/slide terminals). Confirm bulb envelope fits behind lenses.
  • Wattage & Lumens: Match OEM wattage to preserve UL 924 90-minute runtime. For LED retrofits, choose lumen-equivalent output without exceeding the fixture’s max wattage.
  • Beam Pattern: Pick spot/flood to meet corridor spacing: MR16 (e.g., 12°/24°/36°/60°) or PAR36 (spot/flood). Aim to maintain even egress illumination at your mounting height.
  • Environment & Rating: Use PAR36 sealed beam for outdoor/wet areas; standard bi-pin/wedge lamps for indoor/damp. Check temperature range for freezers or hot mechanical rooms.
  • LED Retrofit Notes: Verify polarity and driver compatibility on DC systems. Choose neutral-white CCT (≈3500–5000K) for high contrast; ensure EMI compliance where required.
  • Life & Maintenance: LED lamps ≈ 25k–50k hrs; halogen/incandescent ≈ 1k–3k hrs. Keep spares and perform monthly/annual tests to catch dim or failed lamps early.
  • System Compliance: Bulb swaps must maintain the fixture’s listing and UL 924 runtime. Higher-watt lamps can reduce battery duration; verify with the fixture’s cut sheet.
  • Compatibility Targets: Common matches include MR16 (6/12/24V), PAR36 sealed beam (6/12V), wedge (906/912/1395), and bi-pin LED retrofits used in remote heads and combo fixtures.

FAQs About Emergency Light Bulbs

What is an emergency light bulb?

It’s a specialty lamp for exit and egress fixtures, designed to provide reliable illumination during power outages so occupants can safely evacuate.

How do I choose the right replacement bulb?

Match the voltage (6V/12V/24V), wattage, and base type (bi-pin, wedge, MR16, PAR36). This info is usually on the fixture nameplate or the existing lamp.

Can I upgrade halogen emergency lights to LED?

Yes. Many LED retrofit bulbs are drop-in replacements for halogen/incandescent. Verify voltage, base, and space behind the lens before installing.

Do emergency bulbs come in different beam styles?

They do. MR16 and PAR36 lamps are offered in spot and flood distributions so you can meet corridor spacing and coverage needs.

Are emergency light bulbs universal?

No. You must match your fixture’s electrical specs and socket/base. Using an incorrect lamp can reduce runtime or damage electronics.

How long do emergency light bulbs last?

LED lamps can reach up to 50,000 hours, while halogen/incandescent typically last 1,000–3,000 hours, depending on usage and environment.

Can I use any bulb outdoors?

No. For outdoor or wash-down areas, use sealed/wet-rated lamps like PAR36 sealed beam units that tolerate moisture, dust, and temperature swings.

When should I replace the bulb vs the entire fixture?

If the fixture is intact and specs match, a lamp swap is fine. If the housing is cracked, discolored, or not charging, consider a new emergency light fixture.

Does mounting type affect replacement or upgrade options?

Yes. For relamps, ensure the lamp fits the aiming and lens of a wall-mounted or ceiling-mounted emergency light. For full upgrades, browse wall-mounted exit signs or ceiling-mount exit signs.
