Start with your current project stage, not a fixture name. A commercial lighting project may involve new construction or tenant improvement, retrofit planning, fixture selection, layout review, controls and installation checks, troubleshooting, or quote approval. Use the pathway below to find the next useful input and choose among category browsing, design support, technical support, quote support, or qualified project review. This hub helps orient commercial lighting projects; it does not replace photometric design, electrical engineering, code interpretation, certification review, or final approval.
Choose Your Next Commercial Lighting Pathway
Use this roadmap as a practical guide, not a required sequence. Start at the stage that matches your project and take the next action shown. The GSA lighting guidance also presents a roadmap rather than a single required process.
| Project stage | Decision to make | Next action or support route |
|---|---|---|
| New construction or tenant improvement | What must the lighting system provide in each space? | Build the site and project brief, then request a layout review if mounting, coverage, controls, or phasing could affect the design. |
| Retrofit | What existing conditions constrain replacement? | Record fixtures, mounting, controls, access, outage timing, and phasing before comparing replacement categories. |
| Fixture selection | Which category and variant fit the task and mounting context? | Compare specifications, electrical inputs, controls, environment, quantity, and installation details. |
| Layout review | Could spacing, distribution, obstructions, or access change quantity or placement? | Send dimensions, plans, mounting details, task areas, and existing fixture locations to design support or a qualified lighting professional. |
| Controls and installation checks | Do the proposed fixtures, controls, documents, and installation conditions align? | Gather the project documents and route electrical, code, certification, and commissioning questions for qualified review. |
| Troubleshooting | Is the issue documented well enough for a product question or escalation? | Record symptoms, timing, control behavior, recent changes, and safe observations. Use technical support for product questions and escalate hazards. |
| Quote approval | Are bids based on the same scope and documents? | Compare quantities, variants, controls, drawings, submittals, exclusions, substitutions, and delivery assumptions before approval. |
Build a Site Brief Before Comparing Commercial or Industrial Lighting
A useful site brief turns a broad request into information for fixture comparison or design intake. Gather the inputs below where available instead of filling gaps with generic assumptions. DOE's commercial and industrial lighting evaluation protocol identifies inventory, quantities, wattage, operating hours, controls, drawings, task and use, dimensions, mounting, and site conditions as practical inputs.
Describe the space in feet: indoor or outdoor use, room or work-area dimensions, ceiling and mounting height, task areas, occupancy pattern, visual priorities, and access conditions. For a replacement, add the existing fixture type and count, mounting method, approximate lamp or light-output information, condition, failure pattern, photographs, and available drawings. When available, building-specific operating hours are more useful than a generic schedule.
Add conditions that could change the shortlist: installation schedule, phasing, outage limits, access equipment, environmental exposure, temperature, dust or moisture, budget, controls goals, and whether the project involves new construction, renovation, or retrofit. If the application is industrial or warehouse-based, use warehouse lighting as a category starting point after defining the brief.
Compare Fixture Categories Against the Project Constraints
Choose a category based on the task and mounting context, then compare variants against the project requirements. High bays may suit an appropriate high-ceiling application, wall packs a wall-mounted perimeter need, and parking lot fixtures an outdoor-area application. These examples point you toward a category; they are not universal product recommendations.
For an industrial or warehouse application, compare linear high bay options with other relevant high-bay categories only after defining the site brief. A different mounting pattern or light distribution may change the layout requirements, so category browsing does not replace a review of the actual space.
For every shortlisted variant, record dimensions, mounting method, voltage, wattage or connected load, light output, CCT, optical distribution, dimming or controls, environmental exposure, installation method, and quantity. Lumen figures, voltage ranges, ratings, warranty language, and model details apply to the exact variant. If the brief identifies a wall-mounted perimeter application, the full-cutoff wall pack details can serve as a product-navigation destination; the project team still needs to match the SKU documents to the installation.
Decide When a Lighting Layout or Design Review Is Needed
Request a layout or design review when spacing, mounting height, distribution, task areas, glare, obstructions, access, or existing-versus-proposed conditions could change fixture quantity or placement. Category browsing is not enough when the purchase decision depends on fixture performance across a defined space. The GSA guidance on photometric review supports treating distribution and maintenance access as design considerations for redesigns and new-luminaire retrofits.
Prepare a scaled floor plan or clear dimensions, ceiling and mounting information, task areas, existing fixture locations, obstructions, controls preferences, access limitations, and schedule or phasing requirements. Explain the unresolved decision, such as placement, coverage, uniformity, glare, quantity, or renovation sequencing. Route regulated design and approval questions to a qualified lighting professional.
Verify Controls, Electrical Inputs, and Documents Before Approval
Use one pre-purchase and pre-installation check to catch mismatches before an order or installation moves forward. This is a document and handoff check, not wiring or code advice.
- Site dimensions: Match the proposed application to the actual room, mounting height, work area, access, and obstructions.
- Task and use: Record the work performed, occupancy pattern, visual priorities, operating hours, and available building-specific data.
- Existing equipment: For a replacement, compare fixture type, quantity, mounting, controls, condition, and known failure patterns with the proposed scope.
- Voltage and total connected load: Compare fixture and driver information with the project's electrical design and total-load assumptions. A qualified professional must handle circuit design and changes.
- Controls: Define objectives and zones, then account for system architecture, sensor and controller locations, wiring or communication needs, compatibility, and commissioning or recommissioning. The GSA controls sequence supports this planning approach, but it is not universal code advice.
- Current documents: Use the exact SKU specification sheet, installation instructions, controls information, drawings, submittals, and approved substitutions. Do not infer IP, NEC, DLC, certification, rebate, or hazardous-location conclusions from a category name. Use wet-location and NEC planning or DLC documentation planning as informational follow-up, not as project approval evidence.
- Environmental and project constraints: Record temperature, dust or moisture exposure, access, phasing, outage limits, disposal, schedule, and other conditions that could affect installation or operation.
When controls or performance requirements are significant, include functional verification or commissioning in the project scope. The IES commissioning process describes commissioning as quality assurance that verifies installed lighting and controls against the owner's and designer's performance criteria, making it broader than simple startup. Qualified electrical or engineering professionals must handle wiring, applicable code, certification interpretation, hazardous-location classification, controls commissioning, and final approval.
Route Retrofit, Troubleshooting, Quote Approval, or Hyperlite Support
Choose retrofit planning when existing fixtures, mounting, circuits, controls, access, disposal, outage timing, or phasing constrain replacement. After installation, choose troubleshooting when you can document the affected fixture or area, symptoms, timing, control behavior, recent changes, installation conditions, and safe observations. Do not perform live electrical testing or circuit changes based on this guide. Route suspected hazards or uncertain faults to a qualified professional, and send product-specific questions to technical support.
For quote approval, compare bids against the same fixture schedule, quantities, mounting and installation details, controls, drawings, submittals, exclusions, substitutions, and delivery or lead-time assumptions. The specification-integrity guidance supports this document-to-document approach as good specification practice, not as a universal procurement rule. Price alone cannot show whether two bids cover the same scope.
Once the unresolved question is clear, take one action: browse the relevant category for a defined application, request design support when a layout or application review is needed, contact technical support for a product or document question, or request quote support when the scope and quantities are organized. We can route the conversation to the appropriate Hyperlite support destination, but no direct support URL, service timing, quote term, warranty outcome, or project-fit promise is established here.
FAQ
How do I start a commercial lighting project?
Identify whether you are planning a new space, replacing existing fixtures, selecting a category, reviewing a layout, checking approval inputs, troubleshooting, or comparing quotes. Then gather the information needed for that stage and route unresolved electrical, code, or design questions for qualified review.
What information is needed to choose commercial lighting fixtures?
Start with space dimensions, mounting height, task and use, existing equipment, operating hours, voltage, connected load, controls, environmental conditions, installation method, quantity, and project constraints. Use the exact variant documents when comparing shortlisted options.
When should I request a lighting layout for a commercial project?
Request one when spacing, mounting height, coverage, uniformity, glare, obstructions, access, distribution, or fixture count could change the purchase decision. Send plans or dimensions, mounting details, task areas, existing locations, controls preferences, and phasing information with the request.
How should I compare commercial lighting quotes and product documents?
Make the bids comparable before focusing on price. Match the scope, quantities, variants, voltage, controls, mounting, load, drawings, submittals, exclusions, substitutions, and delivery assumptions, then send unresolved approval questions to the appropriate project contact.
