Anonymized Warehouse LED Retrofit Case Study

This is an anonymized commercial case study. The customer permitted SparkWise Electric to publish the project details on the condition that the business name, exact address, and any directly identifying details remain private. Every fact below is verified; nothing is invented or inferred to make the project sound bigger than it was.

Project Snapshot

• Facility type: Commercial warehouse / industrial property
• Location: Gainesville, Virginia (Prince William County)
• Property size: 149,198-square-foot industrial warehouse property (per public property listing)
• Lighting work: 30 fixtures converted to LED
• Lamps installed: 120 LED Type B bulbs (4 lamps per fixture average)
• Electrical repair: Faulty lighting branch circuit diagnosed and repaired
• Life-safety work: Approximately 2–3 exit lights restored or replaced with new units and protective wire guards
• Contractor: SparkWise Electric — VA Master Electrician License #2710064102

The Challenge

Warehouse lighting tends to age out in two ways at once: the fixtures themselves get less efficient and harder to maintain, and the supporting electrical and life-safety infrastructure starts showing its age. This project had three connected issues to address.

• Aging or inefficient fixture-level lighting across 30 warehouse fixtures. Older lamp technology in a warehouse this size means more frequent lamp swaps, more ladder time, and inconsistent light coverage as different lamps age at different rates.
• A faulty lighting branch circuit affecting reliability for part of the lighting load. Branch-circuit faults in a warehouse can show up as flickering, intermittent outages on a section of the floor, or breakers that trip under normal load.
• Exit-light protection and condition issues on a small group of egress fixtures. Exit signs are required by NFPA 101 Life Safety Code and the locally adopted IFC; in an active warehouse, they also need physical protection from forklifts, racking, and accidental impact.

The Solution

LED Type B fixture conversion

The lighting upgrade used Type B LED replacement lamps. Type B LEDs are direct-wire (ballast-bypass) tubes — the existing ballasts are removed during the conversion and the LED tubes are wired directly to line voltage. Compared to leaving the legacy ballast in the circuit, ballast-bypass installation eliminates the ballast as a future failure point and removes its parasitic energy draw.

SparkWise converted 30 fixtures with 120 Type B LED bulbs (an average of 4 lamps per fixture). All wiring changes inside the affected fixtures were performed by a licensed electrician under VA Master Electrician License #2710064102.

Lighting branch circuit troubleshooting and repair

The faulty branch circuit was diagnosed and repaired in-house. Branch-circuit troubleshooting in a warehouse usually involves isolating the circuit at the panel, identifying the fault location (loose connection, damaged conductor, failed device, or compromised junction), making the repair, and re-energizing under load. The repair restored normal operation to the affected lighting section.

This kind of work is a natural fit for our commercial electrical repair service, which is the side of the business customers usually call when something is already broken rather than when something is being upgraded.

Exit-light restoration with wire guards

Approximately two to three exit lights were either restored to working order or replaced with new units. Each of the addressed fixtures was fitted with a protective wire guard. In an active warehouse with forklift traffic and racking near walls, wire guards are a small piece of hardware that keeps exit signs functional through accidental impacts that would otherwise damage the housing or break the lamp.

Exit signs are required to remain illuminated continuously and to operate on backup power if normal power is lost — both points of NFPA 101 the inspector will look at. Wire guards don’t change the code requirement, but they keep the fixture operating reliably between inspections.

Why This Matters for Warehouse Facilities

This project is a fairly typical mid-size commercial warehouse electrical scope — lighting upgrade plus repair plus life-safety work, all completed in coordinated visits. The category-level benefits a property manager or facility lead can expect from work like this:

• Safer visibility on the warehouse floor — LEDs deliver consistent light output across all fixtures from day one, with no warm-up period and no end-of-life dimming.
• More reliable lighting operation — ballast-bypass LED conversion removes one of the most common failure points in commercial fluorescent fixtures, and a clean branch-circuit repair restores reliability to the affected section.
• Reduced ongoing maintenance burden as a category — LEDs typically last several times longer than legacy fluorescent or HID lamps, which means fewer lamp swaps, fewer ladder hours, and fewer service calls. (We aren’t claiming a specific number of years or a specific dollar figure on this project.)
• Code-current life-safety lighting — functioning, protected exit signs along the means of egress are a baseline life-safety expectation in any commercial occupancy. This work brought the affected fixtures back to working condition.

What We Are NOT Claiming on This Project

To stay accurate, here is what this case study deliberately does not claim:

• A specific energy-savings percentage or dollar figure
• A specific reduction in maintenance hours or service calls
• Customer business name, branch identity, or industry detail beyond “warehouse / industrial property”
• A specific project timeline or completion date beyond “early 2026”
• Permit numbers or jurisdiction-specific permit details
• Customer testimonial or quoted feedback
