Emergency lighting testing is one of the most important maintenance tasks for commercial life-safety equipment. Exit signs and emergency lights are installed for the moment normal power fails, so they need to be checked regularly instead of only noticed during an outage.
Requirements can vary by jurisdiction, building type, and adopted code, but many facilities follow a monthly quick test and a longer annual test. Always confirm the exact rules with your local authority having jurisdiction.
What is the monthly emergency lighting test?
A monthly test is usually a short functional check. The goal is to confirm that each emergency light turns on when normal power is interrupted and that the lamps or LED heads are aimed correctly.
Many fixtures have a test button. Pressing it simulates a power failure and switches the fixture to battery operation. During the test, look for dim lamps, failed heads, damaged housings, loose mounting, missing faceplates, or batteries that do not engage.
If a fixture fails the monthly test, replace or repair it promptly. You can compare standard emergency lights and exit sign and emergency light combos if the unit needs replacement.
What is the annual emergency lighting test?
The annual test is typically longer and verifies that the battery can support the fixture for the required duration. For many commercial emergency lighting systems, that means a 90-minute discharge test, but you should verify the requirement for your building and location.
During the annual test, inspect the full path of egress. The fixture should provide usable illumination in corridors, stairs, exit doors, and other required areas. A light that turns on but points at the wall may still fail to do its job.
What should you record?
Keep a simple inspection log with the fixture location, test date, result, repairs made, and the person who performed the test. This record can help during inspections and makes it easier to spot repeat failures.
Common notes include failed battery, failed lamp head, damaged housing, no AC indicator, missing test button, or fixture not aimed at the egress path.
When self-testing fixtures help
Self-testing emergency lights can reduce manual work by running automatic diagnostics and showing status through an indicator light. They do not eliminate the need to inspect the building, but they can make failures easier to identify between scheduled checks.
If you are upgrading fixtures, compare the maintenance needs of standard emergency lights, self-testing emergency lights, combo exit signs, emergency light batteries, and related emergency backup drivers.
Testing exit signs too
Exit signs with battery backup should also be tested. During a power outage, the sign needs to remain visible so occupants can follow the exit route. If you are replacing old fixtures, LED exit signs are efficient, widely available, and commonly used in commercial spaces.

Bottom line
Emergency lighting testing keeps your backup lighting ready for the one time it truly matters. Build a monthly and annual routine, document the results, and replace failed fixtures quickly so your exit paths stay visible during an outage.
