How to Save on Commercial Lighting Using Secondhand Fixtures

Introduction

Installing lighting in a commercial space can be very expensive, with new fixtures costing thousands of dollars. However, there are ways to save significantly on commercial lighting costs by using secondhand or reused fixtures. In this article, I will provide an in-depth guide on how businesses can save money on their lighting needs by using used commercial lighting fixtures.

Assess Your Lighting Needs

The first step is to determine your lighting requirements. Consider the size of the space, what kind of activities will take place there, and the ambiance you want to create. This will help you figure out what types of fixtures you need and how many. The major factors to consider are:

• Space size and ceiling height - Larger spaces and higher ceilings mean you need more powerful and taller fixtures. Measure the dimensions and ceiling height to determine what will sufficiently light the area.

• Task lighting - Task areas like workstations require brighter, more focused light. Determine what stations or zones need task lighting.

• Ambient lighting - For areas where general, background lighting is needed. Ambient lighting doesn't have to be as bright.

• Accent lighting - Used to highlight displays, architectural elements, artworks, etc. Accent lighting creates visual interest.

• Number of fixtures - For uniform lighting, you need adequate fixture coverage. Light levels decrease exponentially with distance.

Find Used Commercial Lighting Fixtures

There are several places I can look to acquire used commercial-grade lighting fixtures at discounted prices:

• Lighting fixture liquidators - Specialized companies that sell new and used lighting removed from buildings and warehouses. This can include name-brand fixtures at 50-75% off retail price.

• Architectural salvage stores - Vintage and antique stores may have old commercial lighting fixtures in good restored condition. These add visual interest.

• Online listings - Check auction sites and online classifieds for people selling used commercial fixtures locally. Meet to inspect condition.

• Closing businesses - Talk to owners of buildings or venues going out of business. They may be willing to sell their lighting fixtures.

• Lighting contractors - Companies that install lighting may have old demo models or overstock fixtures to sell for low prices.

Evaluate Condition of Used Fixtures

When acquiring used commercial lighting, carefully inspect each fixture for functionality, safety, and cosmetic condition:

• Electrical - Check that wiring and ballasts/drivers work properly and are up to code. Test to make sure bulbs turn on.

• Mounts - Make sure mounting brackets or hardware are intact and undamaged. Fixtures must mount securely.

• Reflectors and lenses - Look for pitting, corrosion, dents, or paint flaking. This reduces light quality.

• Housings - Ensure housings don't have large paint scratches, dents, or rust.

• Bulbs - Secondhand fixtures won't come with bulbs. Factor cost of replacement bulbs.

• Testing - Ask sellers if fixtures can be tested onsite or have electrician test on receipt.

Clean and Refurbish Used Fixtures

Gently clean fixtures of dirt, grime, or flaking paint. Use mild cleanser and soft cloth to avoid scratching finishes. If needed, fixtures can be refurbished by:

• Repainting - Lightly sand surface and spray paint with new finish using lighting fixture paint. Match existing or customize color.

• Polishing - Use metal polish and buffing pad to restore shine to metal components.

• Replacing components - Swap out old yellowed lenses or reflectors and upgrade wiring as needed.

Proper restoration makes used fixtures look fresh and new while being cost-effective.

Calculate Energy Efficiency

While used fixtures are cheaper, they may be less energy efficient than new LED technology. When purchasing:

• Check wattage - Higher wattage incandescent and fluorescent fixtures consume more electricity.

• Consider upgrades - Can used fixtures be upgraded with LED lamps or retrofitted with LED boards? This improves efficiency.

• Calculate the long-term energy savings of efficient LEDs which can offset higher upfront cost.

• Compare utility rebates for installing energy efficient fixtures which can make the upgrade cost-neutral.

• Weigh benefits of smart lighting controls like occupancy sensors and daylight harvesting for automation.

Install Properly and Safely

To properly install used commercial lighting:

• Follow all electrical codes for commercial projects. Consider hiring a certified electrician if unfamiliar.

• Mount securely to prevent vibration and slipping. Use seismic braces in earthquake-prone regions.

• Connect wiring correctly. Use wire nuts, terminal blocks, or connectors to join wires securely.

• Ground electrically - Attach ground wires properly for safety. Consult electrician if unsure.

• Distribute lighting evenly to avoid dim or dark areas. Lighting design factors like fixture height, spacing, and arrangement still apply.

• Have repairs done by qualified electrician if fixture malfunctions or hazards are found. Never compromise safety.

Conclusion

With diligent sourcing, inspection, restoration, and proper installation, used commercial lighting can provide incredible cost savings over new fixtures. While requiring more legwork, secondhand fixtures give the same brightness and ambiance for a fraction of the price. Consider using this guide to take advantage of reused fixtures and save on lighting costs for your next commercial project.
