Tungsten light bulb 24 V 18 W for emergency light unit (LUMT1, LUMT2)

24 V 18 W tungsten replacement bulb for emergency lights

The 24 V 18 W tungsten bulb (LA249) is the filament replacement bulb designed for emergency lighting units and the LUMT1 and LUMT2 spotlights. More powerful than the 6-volt version, it is used on units running at 24 volts and delivers an intense backup beam during a power outage. It is the part you replace as soon as a spotlight goes out or dims during a test: a new bulb of the correct voltage ensures the lighting will truly guide occupants toward the exits.

The tungsten filament gives warm, immediate light with no warm-up time, which is ideal for emergency lighting that must come on instantly. Replacing the bulb rather than the whole unit is cost-effective maintenance that extends the life of an already-installed fleet of spotlights while keeping it compliant.

Benefits of the 24 V 18 W tungsten bulb

Beyond a simple swap, choosing the bulb with the right specification secures the backup lighting.

Voltage and power matched to 24 V units

Its 24 volts and 18 watts match the specifications of higher-voltage emergency units, preventing overheating and battery overconsumption.

Compatibility with LUMT1 and LUMT2 spotlights

Designed for the LUMT1 and LUMT2 spotlights, the bulb installs as a direct replacement for the original model, with no adaptation.

Worksites and sectors where this bulb is required

Replacing emergency light bulbs is required everywhere backup lighting must stay functional:

• Commercial buildings, offices and apartment buildings fitted with 24 V emergency spotlights.
• Institutional facilities (schools, hospitals, long-term care homes) where emergency lighting is regulated.
• Stores, restaurants and hotels that must keep their corridors and exits lit during an outage.
• Industrial buildings and warehouses subject to emergency lighting system inspection.
• Any maintenance manager replacing a burned-out bulb during a monthly or annual test.

Installation and maintenance of the emergency bulb

Replacement involves removing the burned-out bulb from the spotlight and fitting the new 24 V 18 W bulb into the same socket, with the unit de-energized. After fitting, an emergency-mode test confirms the beam lights up correctly on battery. A short monthly test and a full annual test help spot an end-of-life bulb in time.

FAQ about the 24 V 18 W LA249 tungsten bulb

Which devices is this bulb for?

The LA249 bulb is designed for 24 V emergency lights and the LUMT1 and LUMT2 spotlights. Check the original voltage (24 V) and power (18 W) for another model.

What is the difference from the 6 V 9 W bulb?

The LA249 runs at 24 volts 18 watts, for higher-voltage units, while the LA69 is a 6 volts 9 watts. You must match your unit's voltage.

How often should the bulb be replaced?

As soon as a test reveals a weak or dead beam. A visual check at each monthly test helps anticipate replacement.
