ReluxDesktop
vertical specialistReluxDesktop calculates photometric performance for indoor, outdoor, daylight, and emergency lighting applications.
Built-in photometric-driven lighting layout workflow that turns imported candela distributions into point-by-point results and visual maps.
ReluxDesktop is built around a CAD-style lighting workflow where photometric data drives candela distribution and subsequent light calculations in room coordinates. It supports common photometric file imports so teams can spec luminaires using provided IES and EULUMDAT assets and reuse them across projects. Outputs include quantitative grids and contour-like visualizations derived from the calculation engine, which makes it suitable for iterative lighting schedule work.
A tradeoff is that deeper BIM handoff depends on the chosen exchange path, so some teams still need manual alignment between model units and the lighting calculation coordinate system. ReluxDesktop fits best when repeating the same lighting design process across many rooms using consistent luminaire catalogs and scene templates, rather than when building a one-off analysis.
- +Point-by-point illuminance and luminance outputs for detailed verification
- +Photometric file import workflow supports IES and EULUMDAT luminaire data
- +Lighting layout tools reduce manual geometry rework between iterations
- +Scenario runs support rapid comparison of multiple design options

DIALux evo
vertical specialistDIALux evo designs, calculates, and documents indoor, outdoor, street, and emergency lighting projects.
Point-by-point illuminance calculation with isolux contour output tied directly to imported photometric data.
DIALux evo fits teams that already manage luminaire selection via photometric data and need predictable lighting layout outputs for rooms, corridors, and outdoor spaces. It handles photometric file import and then runs illuminance calculations that can be inspected with isolux contours and false-color rendering. Geometry input workflows connect to CAD and BIM exchange so studies can reference actual building elements rather than schematic grids.
A key tradeoff is that advanced simulation tasks depend on disciplined model setup, especially when surface properties and light loss factor assumptions are inconsistent across iterations. A common fit is iterative luminaire placement for compliance-driven design packages where fast comparison of variants matters more than custom computation pipelines.
- +Photometric file import drives repeatable candela-based calculations
- +Illuminance results render with isolux contours and false-color views
- +CAD and BIM exchange supports geometry-grounded lighting studies
- +Variant comparisons speed luminaire layout iteration cycles
- –Advanced studies require careful surface and light-loss-factor setup
- –Automation and API-based provisioning are not the primary workflow
- –Complex BIM model prep can slow first-time study setup
- –Scriptable customization is limited versus code-first simulation tools

How to Choose the Right luminaire software
This buyer's guide covers luminaire software tools across five common workflows: photometric file import, point-by-point illuminance and luminance calculation, isolux-style contour and false-color rendering, and BIM or CAD-connected layout iteration. It also compares how ReluxDesktop, DIALux evo, and other tools handle repeatable outputs from imported candela distributions, then packages the differences into concrete selection criteria.
The discussion includes TracePro for ray-traced study needs, AGi32 for CAD-prepared geometry analysis, and LightStanza when schedule and switching assumptions must drive the calculated outcomes. Each tool review section focuses on what the software generates from a lighting model and how that output stays consistent as teams revise luminaire placement and operating assumptions.
Luminaire software for photometric-driven lighting layout, analysis, and BIM-linked specification
Luminaire software imports photometric data such as IES and EULUMDAT luminaire distributions, then runs point-by-point illuminance and luminance calculations to produce isolux contours and false-color views for localized verification. Teams use these outputs to validate lighting layout decisions based on candela distribution inputs rather than purely visual placement. ReluxDesktop builds that workflow around a photometric-driven lighting layout that converts imported distributions into point-by-point results and visual maps.
DIALux evo similarly centers on photometric-driven, point-by-point illuminance calculation with isolux contour output tied to imported photometric data. The software category also spans specialty study behavior such as TracePro ray-traced point-by-point calculations and LightStanza schedule-driven simulation, which change what must be configured before results are meaningful.
Luminaire software evaluation criteria that affect calculation repeatability and governance
Luminaire software needs repeatable photometric-driven outputs so teams can validate changes in luminaire placement and operating assumptions without reworking the entire study. That repeatability depends on how photometric file import feeds point-by-point illuminance and luminance calculations and how consistently isolux-style contours and false-color maps are generated from the same imported candela distributions.
Teams also need control depth for multi-person workflows because BIM exchange, daylight and glare studies, and lighting schedule assumptions can shift results if geometry units, surfaces, or study parameters drift. Tools that expose stronger automation and an explicit integration surface reduce manual rework when projects require repeated layouts and recurring luminaire libraries.
Photometric import to point-by-point outputs
ReluxDesktop maps imported candela distributions into point-by-point illuminance and luminance outputs and generates visual maps from the same study inputs. DIALux evo and AGi32 also center on photometric file import that drives point-by-point illuminance workflows.
Isolux-style contours and false-color rendering fidelity
TracePro produces ray-traced point-by-point results with isolux contours and false-color rendering in the same study workflow. LiteCalc and Visual Lighting generate isolux-style contour review and false-color maps for rapid localization of illuminance and luminance issues.
Ray-tracing workflow for spec-grade photometric studies
TracePro is the category member built around ray-traced point-by-point calculations tied to luminance outputs and isolux contours. Other tools focus on photometric ingestion and calculation loops instead of a ray-tracing-centric study engine.
Automation and API surface for enterprise provisioning and iteration
ReluxDesktop is the category leader for predictable workflow automation and repeatable study generation with photometric-driven layout iteration. DIALux evo and Visual Lighting keep automation and API-based provisioning as a secondary workflow rather than a primary capability.
BIM exchange and coordinate-unit discipline
ReluxDesktop can support BIM exchange but requires careful unit and coordinate alignment to prevent misplaced placements during round-tripping. CYPELUX and BIM-dependent teams inside BIM pipelines typically depend on their surrounding CYPE choices for full exchange coverage.
Daylight and glare coverage tied to study setup complexity
ReluxDesktop and TracePro require extra setup steps when daylight and glare studies must be meaningful from scenario to scenario. LightStanza limits coverage for daylight and glare versus specialist BIM lighting tools and pushes teams to schedule and switching assumptions for outcomes.
Decision framework for selecting luminaire software by workflow shape
Teams should pick luminaire software based on how the workflow produces results from imported photometric data and how much manual study setup is acceptable before outputs match verification needs. The decision path below starts with the study engine and then moves to integration depth and repeatability under iteration.
Different philosophies appear across the tools. Some products optimize for photometric-driven layout and calculation loops with CAD or BIM geometry attached, while others shift toward ray-traced photometric studies or schedule-driven behavior.
Choose the calculation engine based on how the output must be produced
Select TracePro when ray-traced point-by-point calculations with luminance outputs and false-color rendering are required in the same study workflow. Select ReluxDesktop, DIALux evo, or OpenLumen when point-by-point illuminance and luminance outputs must be generated from imported candela distributions with repeatable layout-linked calculations.
Pick the output style for what reviewers need to read
Choose DIALux evo when isolux contour output tied directly to imported photometric data must support iterative room layout decisions with CAD or BIM geometry. Choose LiteCalc or Visual Lighting when teams need isolux-style contour review and false-color visualization during lighting layout reviews without heavy BIM orchestration.
Decide whether schedules and switching assumptions must drive outcomes
Choose LightStanza when calculated outcomes must reflect a lighting schedule and switching inputs that change results based on operating time assumptions. Choose tools like ReluxDesktop or AGi32 when the primary deliverable is photometric-driven illuminance and luminance verification on a static layout.
Set the integration expectation for BIM coordination and unit alignment
Choose ReluxDesktop when BIM exchange is needed but teams can enforce unit and coordinate alignment discipline during round-tripping. Choose CYPELUX when lighting calculations must live inside a CYPE project workflow and full BIM exchange depends on the surrounding CYPE CAD and BIM pipeline choices.
Assess whether automation is required for repeated schemes and recurring libraries
Choose ReluxDesktop when repeatable luminaire layouts and photometric-driven outputs must be regenerated often and automation is part of the operational expectation. Choose DIALux evo or AGi32 when the workflow can remain centered on manual study runs because automation and API-based provisioning are limited.
Account for study setup time for daylight and glare scenarios
Choose ReluxDesktop when daylight and glare scenarios are required and teams are prepared for extra setup steps per scenario. Choose LightStanza when daylight and glare are not the main deliverable and schedule-driven simulation must dominate the decision workflow.
Who luminaire software selection fits best
Luminaire software fits teams that must turn IES or EULUMDAT luminaire distributions into point-by-point illuminance and luminance outputs and then read isolux contours and false-color maps consistently across layout revisions. The best fit depends on whether the work is photometric-driven layout and verification, ray-traced spec-grade studies, or schedule and switching simulation.
The audience segments below reflect where each tool’s workflow aligns with real study expectations and where integration or automation limitations change outcomes.

BIM-heavy organizations that coordinate geometry exchange and units
ReluxDesktop and CYPELUX fit teams that can manage BIM exchange discipline and treat unit and coordinate alignment as a controlled workflow step.
Common selection and implementation mistakes in luminaire software projects
Luminaire software projects often fail when study setup assumptions drift across iterations or when integration handoffs introduce silent geometry misalignment. The pitfalls below map to the places where outputs change in practice even when the lighting layout appears unchanged.
Most mistakes fall into photometric workflow setup, BIM exchange discipline, and automation expectations for recurring study generation.
Treating BIM exchange as a plug-and-play step instead of controlling unit and coordinate alignment
ReluxDesktop supports BIM exchange but requires careful unit and coordinate alignment to avoid misplaced luminaires during coordination.
Assuming automation and API-based provisioning are available for enterprise iteration
DIALux evo and AGi32 keep automation and API-based provisioning as a secondary workflow, so plan repeated study runs around manual iteration rather than expecting deep provisioning hooks.
Underestimating daylight and glare scenario setup time in photometric-first tools
ReluxDesktop and TracePro need extra setup steps for daylight and glare scenarios so teams should allocate time for scenario-specific inputs instead of reusing a single baseline configuration.
Using schedule-first tools for deliverables that require broad daylight and glare coverage
LightStanza is limited in daylight and glare evaluation compared with specialist BIM lighting tools, so it is better aligned to schedule and switching driven simulation outcomes.
