Best Commercial Lighted Exit Signs AI pick
Chosen by an AI model from its trained knowledge, with its reasoning.
AI pick (line): Lithonia Lighting Quantum LQM LED Exit Sign
A thermoplastic LED exit sign with field-selectable faces and directional chevrons and an optional battery backup, so one stocked unit covers most install situations.
Not for: Spaces that need lighting over the door as well, where an exit/emergency combo is better, and sites with no power at the sign location, where photoluminescent signs suit better.

Lithonia Lighting Quantum LHQM LED Exit/Emergency Combo (line)

What the AI looks for in Commercial Lighted Exit Signs
- Letter color per local code
- Red or green as your jurisdiction requires. Many US cities mandate red, and some states require green. The wrong color fails inspection, so choose a field-changeable unit if unsure.
- Listing and letter size
- Must be UL 924 listed, with letters at least 6 inches high and a 3/4-inch stroke for internally lit signs. These are the NFPA 101 and IBC legibility requirements.
- Battery backup
- Must provide at least 90 minutes on battery unless fed from a generator or central inverter. The sign must stay lit during the egress period after power loss.
- Faces and directional arrows
- Single or double face, with knock-out chevrons chosen for the mounting position (wall, ceiling or end). A sign seen from both corridor directions needs two faces.
- Self-diagnostics
- Recommended in buildings with many signs. It cuts monthly and annual test labor and flags dead batteries.
Brands that matter
- Lithonia Lighting: Quantum LQM and LHQM lines are contractor staples.
- Sure-Lites: Cooper or Eaton exit and emergency lines.
- Dual-Lite: Exit signs in thermoplastic and die-cast housings.
- Exitronix: US exit sign specialist, including low-profile and edge-lit units.
- Brady: Photoluminescent and non-electric safety signage.
What to avoid
- Signs without a UL 924 listing.
- Tritium signs, unless you have a disposal plan, since they are regulated radioactive devices.
- Buying a fixed-color sign before checking local code.
Questions
Red or green?
Whichever your local authority requires. Some jurisdictions mandate one. If unsure, buy a field-selectable unit.
