Quick answer: Start a commercial LED lighting retrofit with an inventory of fixtures, operating hours and problem areas. Evaluate light quality, compatible controls, installation access and emergency lighting before choosing equipment. Then compare the complete installed scope and check utility-program eligibility before purchasing. Energy savings and payback depend on your building's actual baseline.

An office in West Des Moines, a retail space in Ankeny and a warehouse in Des Moines can have very different lighting needs. Desk work, merchandise displays and high storage racks should not be treated as the same design problem. These are planning examples, not claims about individual Cruiser projects.

Cruiser Electric's commercial lighting retrofit service helps businesses plan upgrades around visibility, daily operations and maintenance. A useful estimate starts with what is installed today and what you want the space to do better.

What should a commercial lighting assessment include?

Record the existing fixture and lamp types, quantities, condition and hours of operation by area. Note complaints such as glare on screens, uneven light, flicker or repeated failures. Also document ceiling heights, access restrictions and who controls the space.

  • Offices and reception: desk visibility, screen reflections, meeting-room flexibility and occupant comfort.
  • Retail and customer areas: merchandise appearance, display changes and the transition between daylight and electric lighting.
  • Warehouses and shops: task visibility, rack layout, mounting height and access for future service.
  • Exterior areas: entrances, loading areas, operating schedules and light directed toward neighboring property.

Bring floor plans if available, recent utility bills and a realistic schedule for each area. If the project includes a new tenant layout, coordinate lighting with tenant-improvement electrical work so circuits, switches and the floor plan are considered together.

Choose useful light, not just a lower wattage

Watts describe electrical input; they do not tell you whether people can see their work comfortably. Evaluate light output and distribution alongside glare, color appearance and consistency. The U.S. Department of Energy's LED basics explains why color appearance and color fidelity are part of lighting quality.

Compare lamps, retrofit kits and complete fixtures

The best approach depends on existing equipment condition and compatibility. A replacement lamp, a listed retrofit kit and a complete luminaire are different options. Ask how the proposed approach handles drivers or ballasts, dimming, fixture condition, maintenance and warranty coverage. Do not assume every LED lamp can be installed in every existing fixture.

Evaluate a representative area before a large rollout

For a large or varied building, discuss a sample area or other practical way to evaluate the proposed light. Review it from the positions where people work, including screens, counters and aisles. This gives the owner a clearer basis for choosing equipment than a catalog photograph alone.

Which lighting controls fit the building's schedule?

Controls should match occupancy and daylight patterns. A storage room used intermittently is different from a continuously occupied work area. Consider appropriate occupancy sensing, scheduling, dimming and daylight response, with a clear way for staff to operate the system.

The DOE's lighting-controls guidance emphasizes defining objectives and checking system capabilities and documentation. Specify compatible fixtures and controls together, then allow time to set up zones, sensor coverage and operating schedules. A system that is installed but poorly configured may not deliver the intended benefit.

How should you estimate energy savings and project cost?

Compare existing input wattage, proposed input wattage and annual operating hours for each group of fixtures. A basic lighting-energy estimate is: (existing watts minus proposed watts) × fixture count × annual hours ÷ 1,000 = annual kWh reduction. Account separately for changing operating hours or controls so savings are not counted twice.

For illustration only, reducing 40 fixtures from 100 watts to 50 watts at 3,000 hours per year would reduce lighting energy by 6,000 kWh annually. That is not a Cruiser project result or a savings guarantee. Dollar savings require the applicable electricity rate; demand charges, maintenance, controls and other factors need separate evaluation.

Ask for a scope that identifies fixtures, controls, labor, access equipment, disposal, commissioning and required electrical work. A low equipment price does not represent the full installed cost. If there are existing circuit problems, address them through commercial electrical service work rather than expecting new fixtures to resolve them.

Are lighting incentives available for Iowa businesses?

Check with the utility serving the actual account before purchasing. For eligible MidAmerican customers, the current business discounts and rebates program lists qualifying lighting equipment and participation requirements. Its 2026 Instant Discounts rules distinguish one-for-one replacements from lighting redesigns; custom projects may need approval before purchase and installation.

Program eligibility, equipment requirements, funding and deadlines can change. Confirm the correct program for your account and proposed scope. Do not assume every Greater Des Moines property has the same electric provider, every LED replacement qualifies, or Cruiser's participation in a utility program without confirmation. Treat an incentive as verified only after the utility or participating provider confirms it.

Plan installation around access, permits and ongoing business

Discuss occupied work areas, ceiling access, lifts, stock protection and any necessary circuit shutdowns. Ask whether work can be phased by area and what schedule is feasible. A contractor should confirm the sequence before anyone promises uninterrupted operation or a particular completion date.

Include exit and emergency lighting in the assessment so a general-lighting upgrade does not overlook life-safety equipment. Confirm applicable permit and inspection requirements with the responsible jurisdiction; Iowa DIAL's electrical permitting information is a starting point. Plan the handling of removed lamps and equipment, too. The University of Northern Iowa's fluorescent-bulb recycler directory can help identify recycling options for older lamps.

Prepare for a Greater Des Moines lighting walkthrough

  • List the spaces, fixture quantities and known lighting problems.
  • Provide normal hours, seasonal schedule changes and access limitations.
  • Identify the utility account and ask about incentives before equipment is ordered.
  • Agree on priorities: visibility, comfort, lower energy use, easier maintenance or a combination.
  • Ask how controls will be tested and how staff will learn to use them.

Frequently asked questions

Do all commercial LED retrofits qualify for a rebate?

No. Eligibility depends on the utility account, program, existing equipment, proposed products and timing. Confirm current requirements before purchasing; some projects need preapproval.

Can we keep our existing fixtures?

Possibly. An assessment should compare compatible replacement lamps, retrofit kits and complete fixtures based on condition, light quality, controls and maintenance. Existing fixtures are not automatically suitable for every LED product.

Can a lighting retrofit happen while the business stays open?

Some work can be phased around occupied areas, but access restrictions and circuit shutdowns may affect operations. Agree on a practical installation sequence and schedule before work begins.

How much will a lighting retrofit save?

Savings depend on existing and proposed wattage, operating hours, controls and the electricity tariff. Request a documented estimate using your building’s baseline rather than relying on a universal percentage or payback period.
