Comparison Table
Relux
enterpriseLighting planning and visualization software for architectural daylight and artificial lighting calculations.
View-stable project workflows that keep camera angles and re-render outputs consistent after fixture edits.
Relux centers on an offline editor workflow where designers build or import a lighting scene, assign fixtures from a library, and iterate renders for review packs. Fixture placement and parameter changes propagate through the project so teams can re-render the same views after layout edits. The product is a strong fit when lighting design work is dominated by layout iterations, multiple camera viewpoints, and consistent documentation outputs.
A key tradeoff is that advanced automation and integration depth are narrower than software built around full console emulation or deep automation APIs. Relux can still handle production handoff via project exports and repeatable scene states, but it is less aligned with large-scale provisioning of external control systems. It works best when the deliverable cycle matters more than high-throughput programmatic scene generation.

Assuming camera alignment stays stable after CAD updates without a dedicated camera matching workflow
Capture explicitly supports camera matching for review alignment across revised CAD layouts, while tools centered on fixture iteration may require disciplined camera management when views must match.
Purchasing a GUI-centric visualization workflow when repeatable luminance comparisons drive decisions
Radiance focuses on physically based ray tracing with sampling control for deterministic outputs, while Radiance-style render fidelity typically requires more specialist time for scene setup and parameter tuning.
Expecting advanced automation and batch rendering integration without checking automation and extensibility depth
Relux places limited emphasis on automation and external control integration, and LightStanza also has limited automation depth for cue timelines and large lighting programming structures.
Using CAD inputs without preparing geometry geometry fidelity for photometric simulation tools
