Fluorescent light bulb 7 W for lit emergency "Exit" signs

7 W fluorescent replacement bulb for Exit signs

The 7 W fluorescent bulb (LA7F) is the replacement bulb designed for illuminated emergency "Exit" panels and signs. It is the part you replace when a fluorescent sign weakens, flickers or goes out: by restoring uniform lighting to the panel, it ensures the word EXIT stays perfectly legible, both in normal operation and during a power outage on the backup battery. A well-lit sign is an essential evacuation marker, and a single end-of-life bulb can compromise the whole signage.

Fluorescent technology provides diffuse, even lighting, ideal for backlighting an "Exit" panel legibly from every angle. Replacing only the bulb rather than the whole sign is cost-effective maintenance that extends the life of an already-installed fleet of signs while keeping the signage compliant.

Benefits of the 7 W fluorescent bulb for Exit signs

Beyond a simple swap, choosing the right bulb maintains the legibility of the evacuation signage.

Even lighting of the Exit panel

Diffuse fluorescent light backlights the panel uniformly, with no shadow areas, keeping the word EXIT legible from a distance and from different angles.

Compatibility with Exit panels and signs

Designed as a replacement part for fluorescent illuminated Exit signs, the 7 W bulb fits into the original socket for simple maintenance.

Worksites and sectors where this bulb is required

Replacing Exit sign bulbs is required everywhere evacuation signage must stay legible:

• Commercial buildings, offices and apartment buildings with fluorescent Exit signs.
• Institutional facilities (schools, hospitals, long-term care homes) where exit signage is regulated.
• Stores, restaurants and hotels that must keep their exits clearly marked.
• Industrial buildings and warehouses subject to emergency lighting system inspection.
• Any maintenance manager replacing a failing bulb during a periodic test.

Installation and maintenance of the fluorescent bulb

Replacement involves removing the worn fluorescent bulb from the Exit panel and fitting the new 7 W bulb into the same socket, with the sign de-energized. After fitting, an emergency-mode test confirms the panel lights up correctly on both mains power and battery. A visual check at each periodic test helps anticipate a replacement.
