Emergency and Exit Lighting in the Phoenix Valley

Exit and emergency lighting is the system nobody thinks about until an inspection or an actual emergency, and it is also the system most likely to be quietly non-functional. The fixture on the wall looks fine. The battery inside it died two years ago. At The Wire Guy Electric, we install, test, and repair egress lighting for commercial properties across the Valley.

What We Handle

• Exit sign installation and placement along egress paths
• Emergency lighting, both the classic twin-head units and integrated fixtures with battery backup
• Battery replacement, which is the single most common repair on these systems
• Testing and correcting whatever fails it
• Replacing dead or damaged units
• Retrofits of old incandescent exit signs to LED, which cut standby draw substantially across a building with many signs
• Adding coverage where a layout change left a path unlit

Why These Fail Quietly

The fixture is powered and the indicator light is on, so everything appears fine. But the indicator only tells you the unit is receiving power. It does not tell you the battery still holds a charge, which is the only thing that matters when the power goes out.

Batteries have a finite service life, and Arizona heat shortens it. A unit mounted in a warehouse, a stairwell, or anywhere near a roof deck sees ambient temperatures that age a battery considerably faster than the spec sheet assumes.

This is why the only real test is the actual test: kill power to the unit and confirm it illuminates for the required duration. That is a straightforward thing to do on a schedule and the single best way to avoid finding out during an inspection.

Layout Changes Create Gaps

Something we find often: a building's egress lighting was correct when it was installed, then a tenant improvement moved walls, added a corridor, or changed the exit path. The lighting stayed where it was.

Any time a space gets reconfigured, the egress path and its lighting should be reviewed against the new layout. If you are planning a buildout, that belongs in scope from the start. See our tenant improvement page.
