Light bulb 130 V 20T65 with medium socket for emergency "Exit" signs

130 V 20T65 medium-base bulb for older Exit signs

The 130 V 20T65 bulb (LA130M) is an incandescent medium-base bulb designed as a replacement part for illuminated emergency "Exit" panels and signs made in the 1990s. These period signs are still common in existing buildings, and the LA130M restores adequate lighting without changing the whole sign. It is the practical way to maintain older evacuation signage while keeping it legible and compliant.

The 20T65 format and 130-volt rating match the original specifications of these signs, and the medium base fits their socket. Keeping the right bulb avoids makeshift fixes and ensures the word EXIT stays clearly visible. For a sign at the end of its life, an LED retrofit kit remains an attractive option toward more energy-efficient lighting.

Benefits of the 130 V 20T65 medium-base bulb

Beyond a simple swap, this bulb maintains a fleet of older signs without replacing everything.

Replacement part for 1990s signs

The LA130M matches Exit signs from the 1990s, whose original bulbs are hard to find, extending the useful life of existing equipment.

20T65 format and medium base matched

The 20T65 format and medium base reproduce the original specifications, for a direct replacement in the socket with no adaptation.

Worksites and sectors where this bulb is required

Replacing bulbs in older Exit signs is required everywhere this equipment remains in service:

• Commercial buildings fitted with 1990s Exit signs.
• Institutional facilities (schools, hospitals, long-term care homes) with an older sign fleet.
• Stores, restaurants and hotels that must keep their exits clearly marked.
• Industrial buildings and warehouses subject to emergency lighting system inspection.
• Any maintenance manager looking for a replacement bulb for an old sign.

Installation and maintenance of the Exit sign bulb

Replacement involves removing the worn bulb from the panel and fitting the new 130 V 20T65 bulb into the same medium-base socket, with the sign de-energized. After fitting, an emergency-mode test confirms the panel lights up correctly. If the sign is in poor overall condition, consider an LED retrofit.

FAQ about the 130 V 20T65 LA130M bulb

Which signs is this bulb for?

The LA130M is designed for medium-base Exit signs from the 1990s. Check the socket format and original voltage for another model.

What is the difference from the small- or large-base versions?

The small (LA130P), medium (LA130M) or large (LA130G) base depends on your sign's socket. Check the format before ordering.

What if my sign is too old?

If the sign is at the end of its life, an LED retrofit kit lets you convert the old panel to more energy-efficient lighting.
