Spec guide

Photoluminescent Exit Signs Buying Guide

Use these checks to confirm the sign will charge properly, remain visible on the egress path, and fit the project before choosing a model.

01

Charging light

Confirm the sign face receives about 5 foot-candles of continuous light during occupancy so the legend can charge reliably.

02

Viewing distance

Choose 50-, 75-, or 100-foot viewing distance based on corridor length, approach angle, mounting height, and sightline interruptions.

03

Placement and sightlines

Keep the sign visible from the travel path. Use more signs at shorter intervals when turns, doors, columns, or equipment block visibility.

04

Face count and arrows

Match single- or double-face configuration, arrow direction, and legend color to the actual egress route and local plan review.

05

Mounting surface

Confirm wall, ceiling, or end mounting and verify the selected housing works with the substrate, doorway, or corridor condition.

06

Environment

Use wet-location or protected models for exterior, damp, hose-down, or high-humidity areas. Standard models are best for indoor conditioned spaces.

07

Compliance review

Check UL 924 listing, NFPA 101 intent, OSHA visibility expectations, and AHJ acceptance before finalizing a project submittal.

08

Maintenance plan

Document charging-light conditions, keep lamps or fixtures working, and include signs in routine life-safety inspections.

Quick answers

FAQs About Photoluminescent Exit Signs

Expand the questions that match your application, fixture-selection, or compliance review.

Do photoluminescent exit signs require electricity?

No. The sign itself does not use wiring, batteries, or radioactive material. It does need reliable ambient light on the sign face so the material can charge before an outage.

How do photoluminescent exit signs work?

They absorb light while the area is illuminated, then release that stored energy as a visible glow when lights go out. This makes them useful for qualified no-electric egress paths.

How much light is needed to charge the sign?

A common planning target is about 5 foot-candles on the sign face during occupancy. Confirm the selected product instructions and local AHJ expectations before installation.

Are photoluminescent exit signs code compliant?

They can be, when the product is properly listed and installed with adequate charging light. Final acceptance depends on the product listing, project documents, installation, and local AHJ.

When should I choose tritium instead?

Choose self-luminous tritium exit signs where reliable charging light is not available but no-power operation is still required.
