If you are planning a commercial lighting project, one of the first practical questions is usually: how much does a photometric plan cost?
At Stetra Lighting, a typical professional photometric plan generally falls between $220 and $1,000, depending on site size, the number of lighting zones, fixture-selection scope, project information, and the level of permit documentation required.
A small, clearly defined project can stay near the low end of that range. A larger site with multiple calculation areas, property-line checks, fixture selection, code-specific requirements, or several design iterations will usually cost more.
This guide explains what affects photometric plan pricing, what is normally included, and how the scope of a small project can differ from a large multi-zone study.
Typical Photometric Plan Cost
| Project Type | Typical Stetra Price Range | Typical Scope |
|---|---|---|
| Small / straightforward project | $220-$300 | One simple calculation area, fixtures already selected, clean plans |
| Standard commercial project | $300-$500 | Parking lot, small exterior site, warehouse area, or similar scope |
| Larger or multi-zone project | $500-$750 | Multiple calculation zones, more fixtures, property-line review, additional coordination |
| Complex / large project | $750-$1,000 | Large sites, sports areas, multiple building zones, complex geometry, or deeper permit documentation |
These are typical Stetra project ranges, not universal industry prices. The exact quote depends on the drawings, fixture information, jurisdiction requirements, and deliverables needed for the specific project.
What Affects the Cost of a Photometric Plan?
The biggest pricing difference is usually not the number of pages in the final report. It is the amount of modeling, calculation, checking, and design coordination required to produce accurate results.
1. Project Size and Number of Calculation Areas
A single parking lot is usually faster to model than a site with several parking areas, drive aisles, pedestrian paths, building entrances, canopies, loading areas, and property-line calculation zones.
2. Quality of the Base Drawings
A clean CAD file or scaled PDF can reduce setup time considerably. Projects can take longer when the background drawing is incomplete, not to scale, or missing dimensions.
3. Whether the Fixtures Are Already Selected
Complete fixture information can reduce setup work: manufacturer, model, optic, output configuration, mounting height and matching IES file. If fixture selection or comparison is required, confirm it in the quotation. The photometric-analysis guide explains why the exact inputs matter.
For a deeper explanation of how the calculation works, see our guide to photometric plans.
4. Permit and Jurisdiction Requirements
Some projects need a straightforward point-by-point calculation. Others require property-line calculations, uniformity ratios, fixture schedules, BUG or cutoff information, light-trespass review, or local zoning criteria. Requirements vary by municipality and project.
5. Number of Design Iterations
A difficult site may require several simulations to balance minimum light levels, uniformity, glare, spill light, optics, mounting heights, and fixture quantities.
6. Project Type
A warehouse photometric plan may need rack/task calculations, while sports-lighting studies may need different playing areas and viewing checks. Define the actual zones and deliverables before comparing fees.
Real Example: A Smaller, Straightforward Parking Lot
This Stetra project is a useful example of a more straightforward scope. It has a compact parking area around one building, with a relatively simple lighting layout and a limited calculation footprint. That makes it a good visual example of the kind of work that can stay toward the lower end of the typical pricing range when the drawings and fixture information are complete.
A project with a compact footprint, one main exterior area, and fewer design variables is generally faster to model and review than a large multi-zone commercial site. That is the type of scope that can fall toward the lower portion of Stetra’s typical pricing range.
What Is Included in the Photometric Plan Price?
Depending on the project, a Stetra photometric plan may include:
- fixture locations
- point-by-point foot-candle or lux calculations
- average, minimum, and maximum illuminance
- uniformity ratios
- calculation grids
- fixture schedule
- mounting heights
- IES-based calculations
- false-color or iso-foot-candle analysis
- property-line calculations where required
- design notes and calculation assumptions
- a professional PDF report
Real Example: A Large Multi-Zone Photometric Study
The large parking lot example shows how quickly the scope can expand. The site includes several parking fields, multiple buildings and drive aisles, perimeter conditions, and many more fixture locations and calculation points. This type of project requires more model setup, more fixture coordination, more calculation surfaces, and more review of how the different zones interact.
Large multi-zone work is therefore more likely to fall toward the upper end of the pricing range, depending on the permit requirements, fixture-selection scope, and revision needs.
Parking Lot Photometric Plan Cost
A straightforward parking lot project will often fall around $250-$400, while a larger site with several lighting zones, wall-mounted fixtures, property-line calculations, or more complex permit requirements can move higher within the overall $220-$1,000 range.

Why Can Two Photometric Plans Have Very Different Prices?
Two projects can look similar on paper but require very different amounts of work. A clean CAD file, selected fixtures, correct IES files, and clear requirements reduce setup and iteration. A project with incomplete drawings, fixture selection, uncertain pole locations, residential boundaries, or several design options requires more time.
That is why a project-specific quote is more accurate than pricing a photometric plan only by square footage or fixture count.
Can a Manufacturer Provide a Free Photometric Plan?
Sometimes. Manufacturers and sales representatives may provide calculations at no charge when the project is being designed around their fixture line.
Compare what is included, the fixture-selection constraints, deliverable formats and revision terms. A calculation tied to a supplier’s products may fit one project; an independently scoped study may fit another. Ask which fixture options can be evaluated and how the results will be documented.
Is the Cheapest Photometric Plan Always the Best Option?
Not necessarily. The value of a photometric plan comes from identifying problems before fixtures, poles, wiring, and construction are installed.
A layout that looks acceptable on a drawing can still create dark areas, poor uniformity, excessive spill light, glare, unnecessary fixture quantities, or permit-review comments.
How to Keep Your Photometric Plan Cost Lower
Provide complete information when requesting a photometric-plan quote: the current drawings, project city and state, calculation areas, selected fixture/IES data, mounting constraints, review criteria, requested deliverables and target date. The checklist below helps define the scope before work starts.
- The latest site plan or floor plan.
- A scaled PDF or CAD file if available.
- Proposed fixture locations, if already determined.
- Fixture model numbers and IES files, if already selected.
- Mounting heights.
- The project city and state.
- Any permit comments or lighting requirements already received.
- The required turnaround date.
How Long Does a Photometric Plan Take?
Confirm the delivery schedule after the drawings, fixture information and review scope have been checked. Complex geometry, missing inputs, fixture comparisons or additional review rounds can affect timing. Ask for the expected first-report date and the agreed revision scope in the quotation.

Photometric Plan Cost vs. the Cost of Rework
The photometric plan is usually a small part of the overall lighting-project budget. Moving poles, replacing fixtures, changing optics, adding shielding, or responding to permit comments after coordination can be much more expensive.
