Maintained luminaire
An emergency light that's lit in normal use and stays lit when the normal supply fails, often at lower output. A non-maintained fitting is dark until that supply fails. The design and the fire risk assessment decide which a space needs, and the difference matters on a test, because it changes what you expect to see lit and when.
Using Maintained luminaire in context

A distinction worth remembering
Maintained or non-maintained describes what an emergency light does while the normal supply is on. Check which is fitted before a test, so you know what should be lit and when.

Lighting that works when the normal supply fails, so people can find their way out. BS 5266-1 is the code of practice, and power comes from a battery in each unit, a central battery bank or a generator that starts automatically. In England and Wales, article 14 of the Regulatory Reform (Fire Safety) Order 2005 requires it on routes and exits that need lighting; Scotland and Northern Ireland have their own fire safety law. Guidance for England and Wales gives a monthly function test and an annual full discharge test as typical, not as a fixed rule for every site.
