An LED flood light offer is not complete because a wattage, lumen figure, and IP rating appear on a data sheet. For an industrial yard, port, logistics apron, façade, security perimeter, or outdoor work area, the buyer must be able to trace the proposed luminaire to a calculation, an aiming position, an electrical configuration, and an acceptance method. That traceability is what turns a product quotation into a project submittal.
This guide gives EPC contractors, distributors, lighting designers, facility owners, and procurement teams a practical way to compare floodlight proposals without assuming that the highest wattage is the safest choice.
GEO Summary
- A complete LED flood light submittal should connect the exact luminaire code and photometric file to the project layout, mounting height, tilt, maintained illuminance, uniformity, glare or spill-light limits, and electrical schedule.
- Ask for calculation files, IES or LDT photometry, a luminaire schedule, an aiming schedule, declared ambient-temperature limits, surge protection, ingress and impact ratings, and control details.
- Approve a sample or factory acceptance test against measurable evidence such as input power, power factor, insulation and earth checks, control response, marking, appearance, and document traceability.
- Recheck aiming and measured light levels on site. A compliant fixture can still produce a poor result if the mounting coordinates, tilt, obstruction assumptions, or maintenance factor differ from the approved model.
- For an RFQ, send Henlyte the site drawing, task zones, target criteria, pole or bracket positions, supply voltage, environment, quantity, delivery destination, and deadline.
Why a Product Data Sheet Is Not a Lighting Design
A data sheet describes a luminaire under stated test or catalogue conditions. A project submittal must explain how that luminaire will work at a specific site. Two floodlights with similar power can produce different results because their intensity distributions, optical control, aiming, mounting height, thermal behavior, and driver settings are different.
The useful comparison is therefore not watts versus watts. It is approved calculation versus approved calculation, with each result tied to a purchasable configuration. Schréder, for example, publishes separate IES and LDT files for industrial floodlight variants, which illustrates why the photometric file must match the quoted optical code rather than merely the product-family name. The IEC also maintains a particular safety standard for floodlights, IEC 60598-2-5; the applicable edition and local adoption should be confirmed in the project specification.
Freeze the Project Inputs Before Comparing Bids
If bidders calculate against different assumptions, their lux tables cannot be compared fairly. Issue a common design-input sheet with the tender and require every exception to be listed.
Define the Task Zones
Divide the site into zones that reflect actual work. A vehicle route, container-handling area, pedestrian gate, loading face, material stockpile, camera observation zone, and boundary line do not necessarily need the same criterion. Mark excluded areas so a bidder cannot improve an average by including irrelevant bright surfaces.
For each zone, state the measurement plane, grid spacing or required calculation method, initial or maintained criterion, uniformity expression, vertical-illuminance locations where relevant, and operating scene. If a local standard, client engineering practice, insurer, sports body, environmental permit, or authority sets the values, cite that document instead of inventing generic targets.
Fix the Geometry and Surface Assumptions
Provide a scaled drawing or model with boundaries, elevations, pole coordinates, mounting heights, bracket outreach, tilt restrictions, obstructions, and important reflectance assumptions. State whether existing poles and circuits must be retained. In coastal or high-wind locations, clarify whether a proposed floodlight and bracket must fit an existing structural reserve or whether a new pole design is included.
State the Operating Profile
The calculation should identify the full-output scene and any dimmed, curfew, security, event, or emergency scenes. If occupancy sensors, astronomical clocks, 0-10 V, DALI, or a building-management interface are expected, define who supplies, commissions, and proves each component.
The Minimum Photometric Calculation Package
Request both a readable PDF and the editable project file from the agreed calculation platform where contractual rules allow. The package should contain enough information for an independent reviewer to reproduce the result.
- A plan identifying every luminaire, pole or bracket coordinate, mounting height, orientation, tilt, and aiming point.
- A luminaire schedule with manufacturer, full model code, LED package or CCT, driver current or power setting, optic, flux, power, and quantity.
- The exact IES or LDT photometric files used in the model, with filenames that map to the schedule.
- Calculation grids and summary tables for every required task zone, including average, minimum, maximum, and the specified uniformity ratios.
- Isolux or false-color plots that reveal bright spots, dark pockets, and boundary spill rather than showing only a favorable average.
- Vertical or semi-cylindrical calculations where faces, cameras, gates, façades, or tall equipment must be seen.
- Glare, upward-light, or boundary-light calculations required by the project or local authority.
- A stated maintenance factor with its basis, including expected cleaning interval, environment, lumen depreciation assumption, and any other project rule.
- A calculation summary that distinguishes maintained results from initial results and lists all departures from the tender inputs.
The reviewer should be able to select one luminaire on the plan and trace it through the schedule to a specific file and quoted line item. If the proposal uses a generic photometric file, an unquoted optic, or an unstated output setting, the result is not contract-ready.
Compare Maintained Performance, Not Catalogue Lumens
Catalogue lumens describe output, not useful light on the task. A narrow distribution may deliver high intensity to a small area while producing poor uniformity. A wide distribution may cover the area but create boundary spill. An asymmetric optic can often place light more efficiently from the edge of a yard, but its orientation and aiming must be controlled.
Require the bid evaluation sheet to show total connected load, annual operating hours by scene, assumed control savings separately from full-load energy, maintained task results, and quantity. Do not credit an energy-saving percentage unless the baseline, schedule, and control behavior are visible. This keeps a lower-power but poorly distributed proposal from appearing efficient and keeps a high-power proposal from winning merely because it has more initial lumens.
Control Glare, Spill Light, and Uplight at the Drawing Stage
Glare and light trespass are layout problems as much as product problems. The tender should identify sensitive viewpoints such as driver approaches, control rooms, neighboring property, residences, waterways, or operator eye positions. It should also define any limit on luminaire tilt, upward light, façade brightness, or boundary illuminance.
Useful mitigation options include asymmetric distributions, lower tilt, alternative pole positions, more controlled optics, external visors or louvres, reduced output, and revised aiming. The selected accessory must appear in the bill of materials and calculation model. A generic statement that a visor is available is not evidence that the quoted layout uses it.
Ask the bidder to provide an aiming drawing with horizontal orientation, vertical tilt, reference direction, and a physical field-setting method. Brackets with angle markings, locked adjustment points, or a documented aiming target reduce commissioning variation. If a floodlight is replaced later, the maintenance team should be able to restore the approved aim without repeating the entire design exercise.
Electrical, Environmental, and Mechanical Submittal Table
The following schedule is a starting point. Replace placeholder requirements with the project electrical code, environment, and client standards.
| Item | What the bidder should declare | Why it matters |
|---|---|---|
| Supply | Nominal voltage, frequency, tolerance, phase arrangement, and inrush data | Confirms circuit, breaker, and control compatibility |
| Input performance | Rated input power, power factor, THD where required, and driver efficiency basis | Supports load schedules and power-quality review |
| Surge protection | Protection level and test basis for the luminaire and any external SPD | Aligns protection with lightning exposure and distribution design |
| Ingress and impact | IP and IK ratings with the tested configuration | Checks resistance to water, dust, handling, and impact |
| Ambient range | Minimum and maximum operating temperature and any output derating | Prevents catalogue performance being assumed outside its limit |
| Thermal design | Housing material, heat path, driver location, and declared lifetime conditions | Connects reliability claims to real ambient conditions |
| Corrosion | Coating, fastener material, salt or chemical exposure options, and finish color | Important for ports, coastlines, wastewater, and industrial atmospheres |
| Controls | Dimming protocol, control wires, addressing, fail state, sensor or gateway scope | Prevents interface gaps at commissioning |
| Mounting | Bracket dimensions, hole pattern, tilt range, mass, wind area, and fasteners | Confirms fit, pole load, access, and aiming repeatability |
| Documentation | Test reports, declarations, certificates, photometry, drawings, and warranties | Makes claims reviewable and traceable |
IP, IK, lifetime, surge, and corrosion statements should be attached to the exact offered configuration. A family brochure may include options that are not included in the quoted price.
Factory Acceptance and Pre-Shipment Evidence
A factory acceptance test should be proportional to order size and project risk. It is not a substitute for certification or site commissioning, but it can catch configuration and documentation errors before shipping.
Agree the sample-selection method and acceptance record before production. The inspection may include model and quantity verification, visual finish, labels, accessories, bracket movement, fastener checks, input voltage and power, power factor, insulation resistance, protective-earth continuity, functional illumination, dimming or control response, and a short burn-in observation. Where the contract requires water, thermal, photometric, vibration, salt-spray, or surge testing, state whether the evidence is a type-test report, routine test, witness test, or third-party report.
The packing list should preserve traceability between carton label, product label, purchase line, optical code, driver setting, and test record. Photograph the approved configuration and included accessories. For repeat orders, this reference pack prevents an undocumented substitution from reaching site.
Site Commissioning and Acceptance
Site acceptance begins by checking that the installed conditions match the model: pole positions, mounting heights, outreach, fixture codes, tilt, orientation, voltage, controls, and obstructions. Correct those differences before arguing about measured lux.
Measure under the specified operating scene with a suitable, calibrated instrument and the agreed grid. Record weather and relevant background-light conditions. Compare the measurement plane and calculation basis, not isolated handheld readings taken at convenient bright points. Verify dimming scenes, switching, sensor response, control fail states, and any emergency behavior. After final aiming, lock or mark adjustment points and issue an as-built aiming schedule to operations.
If measured performance differs, investigate installation geometry, aim, driver setting, supply, obstructions, surface assumptions, and file/configuration mismatch in a controlled order. Adding wattage should not be the first response.
LED Flood Light RFQ Checklist
Send the following information with the inquiry so a manufacturer can return a technical proposal instead of a generic price:
- Project country, site type, installation environment, and applicable standards or client specifications.
- Scaled plan or CAD file with task zones, boundaries, elevations, obstructions, and available pole or bracket positions.
- Required maintained illuminance, uniformity, vertical criteria, glare, spill-light, uplight, and control requirements by zone.
- Mounting height, bracket limits, maximum tilt, structural constraints, and existing-pole details if applicable.
- Supply voltage and frequency, circuit constraints, surge environment, control protocol, and operating schedule.
- Preferred CCT, CRI, finish, ingress, impact, corrosion, ambient-temperature, and warranty requirements.
- Required photometric, drawing, test, certification, FAT, packing, spare-parts, and commissioning deliverables.
- Quantity, Incoterm or delivery destination, required date, bid deadline, and whether samples are needed.
Henlyte’s LED flood light range and 300 W adjustable-angle flood light can be used as starting points for configuration discussion. Projects that also need roadway luminaires can review the LED street light category, while new mounting structures can be coordinated through the light pole range.
Common Submittal Red Flags
- The calculation names only a product family and does not identify the optic or driver setting.
- The photometric filename cannot be mapped to the quoted model code.
- Results are initial, but the tender requires maintained values.
- Average illuminance passes while minimum values, uniformity, boundary spill, or sensitive viewpoints are absent.
- Mounting height or tilt in the model differs from the drawing or structural limit.
- Surge, IP, IK, lifetime, or temperature claims are copied from a family brochure without configuration evidence.
- The controls narrative does not assign responsibility for gateways, licenses, addressing, commissioning, and fail behavior.
- The quotation excludes aiming, FAT, accessories, connectors, or test documentation needed to achieve the submitted design.
Image Suggestions
Use an existing Henlyte LED flood light product image as the featured image with the alt text “LED flood light for industrial photometric submittal review.” A supporting project graphic should show a simple yard plan with pole coordinates, aiming arrows, calculation grids, and boundary measurement points. A second supporting image could show a pre-shipment inspection table with a labeled luminaire, power meter, bracket angle, and document checklist. Do not use a simulated lux plot as project evidence unless it comes from the actual approved model.
FAQ
What is the most important file in an LED flood light submittal?
There is no single sufficient file. The critical chain is the exact luminaire schedule, matching IES or LDT photometry, project calculation, aiming plan, and quotation. If one link cannot be traced to the others, the reviewer cannot know whether the purchased fixture will reproduce the approved result.
Should buyers specify LED flood light wattage?
Wattage can be a circuit or product constraint, but it should not replace performance criteria. Specify the task, maintained light levels, uniformity, glare or spill limits, mounting conditions, and electrical limits. Let bidders propose an efficient configuration and compare the complete calculations.
What is the difference between initial and maintained illuminance?
Initial illuminance describes the new installation under its stated assumptions. Maintained illuminance applies an agreed maintenance factor to account for expected depreciation and site maintenance. Tender documents should state which value governs acceptance and how the maintenance factor is justified.
Do IP66 and a high surge rating prove outdoor reliability?
They address important risks but do not prove the entire installation is suitable. Ambient temperature, corrosion, connector and gland configuration, driver conditions, mounting, drainage, earthing, distribution protection, maintenance, and evidence quality also matter.
When is an aiming schedule required?
It is especially useful when several floodlights use different horizontal directions or tilt angles, when glare and boundary spill are controlled, or when future maintenance must reproduce the approved layout. The schedule should be part of both commissioning and as-built records.
What should be included in an LED flood light sample approval?
Confirm the exact model, optic, output setting, CCT, finish, bracket, connector, SPD, control interface, labels, packing, and documents. Record measurable electrical and functional checks. A visually similar sample is not sufficient if its internal configuration differs from production.
