Light box signs (also called cabinet signs) use a translucent acrylic or polycarbonate face over an aluminum cabinet, lit from inside with LED or fluorescent modules for consistent day-and-night visibility. We've built and installed them for storefronts, gas stations, medical offices, and retail centers across Harford County, Cecil County, and the greater Baltimore/Wilmington region since 1947. Every cabinet is fabricated in our own shop — nothing is outsourced — and our licensed electricians handle all interior wiring and hookups themselves, so there's no subcontractor to coordinate. Because illuminated signs typically require an electrical permit, our in-house permit department prepares and files the paperwork with your local jurisdiction on your behalf.

Frequently Asked Questions

How much does a light box sign cost?: Light box signs typically range from $1,500 to $8,000 depending on size, whether the cabinet is single- or double-faced, and the illumination type. LED retrofits for existing cabinets cost less than a full new sign since the aluminum housing is reused.
How long do light box signs last?: The aluminum cabinet lasts 20+ years with normal upkeep. LED modules inside typically last 50,000–100,000 hours, or roughly 10–15 years of normal use. The translucent face may need replacement every 8–12 years as UV exposure causes fading.
Can you convert my fluorescent light box sign to LED?: Yes. We retrofit existing fluorescent cabinet signs with LED modules, which use significantly less electricity and last far longer than fluorescent tubes, which also lose light output in cold weather. Our licensed electricians handle the conversion in-house, so there's no separate electrical contractor to schedule.
Do I need a permit for an illuminated sign?: In most of our Maryland, Delaware, and Pennsylvania service area, yes — illuminated signs generally require an electrical permit, and some locations also require a zoning or design-review variance. Our in-house permit department handles the application and filing with your local jurisdiction, so you don't have to navigate that process yourself.
