Dialux 3.14 — Complete Guide & Practical Tips
3. Bulk Editing Power
In version 3.14, you can select 500 luminaires, open a spreadsheets-like property dialog, and change the lamp type, wattage, and reflector in 3 seconds. In evo, bulk editing large arrays still feels sluggish.
5. Rendering vs. Documentation
Rendering (3.14 is TERRIBLE):
- Outputs flat, low-res OpenGL renders. No shadows, no textures that look real. You use this for technical reports, not client presentations.
Documentation (3.14 is EXCELLENT):
- The Output Wizard: Generates professional PDFs with false-color isolux diagrams, utilization factor tables, and UGR (Unified Glare Rating) sheets.
- UGR Calculation: It follows CIE 117-1995 exactly. Later evo versions changed the observer position logic, causing disagreements with consultants. Many specs still require "DIALux 3.x UGR."
Practical Tips & Best Practices
- Use accurate photometric files: always prefer manufacturer-supplied IES/ELUMDAT files for realistic results; verify the photometric file version and photometric type (Type C vs Type A).
- Start with templates: load a standard or previously used project template to keep consistency (units, standards, reflectances).
- Grid spacing: aim for a calculation grid of ~0.5–1.0 m for interiors depending on room size; finer grids increase accuracy but slow calculations.
- Maintenance factor: set a realistic maintenance factor (e.g., 0.8–0.7 for office lighting) based on environment and maintenance plan.
- Ceiling reflectance matters: default values (ceiling 70%, walls 50%, floor 20%) are common starting points—adapt to actual finishes.
- Avoid overlighting: target standards (lux) are guides; evaluate uniformity and visual comfort, not just average lux.
- Control & glare: run UGR and glare checks (where supported) and adjust optics or add diffusers to reduce discomfort.
- Luminaire placement heuristics: keep luminaires aligned with room geometry and workplane layout (desk rows, aisles); center luminaire rows over workstations for uniformity.
- Use symmetrical layouts where possible: regular grids often produce the best uniformity for general lighting.
- Tilted/angled fixtures: when aiming spotlights or wall-washers, use the software’s aiming tools and verify with rendered views—small aiming changes can noticeably affect illuminance distribution.
- Combine daylight and electric lighting: simulate daylight contribution with windows/sky to optimize energy and control strategies (daylight harvesting).
- Save incremental versions: keep versioned files (v1, v2…) before major layout changes so you can compare calculation results.
- Validate suspicious results: if values look unrealistic, check unit settings, photometric file scale, maintenance factor, calculation height and whether luminaire multipliers were applied twice.
- Use manufacturer catalogs: importing a manufacturer's catalog ensures correct mounting heights, dimensions and product codes for schedules.
- Batch export: export luminaire schedules and parts lists for procurement and cross-check them with manufacturers’ product codes.
- Performance: large projects with many rooms or fine grids can be slow—close unneeded views, limit texture complexity, and run overnight if necessary.
- Documentation: include a short methodology section in reports listing standards used, calculation plane height, maintenance factor and reflectances.
Key Clarifications
-
No official "Dialux 3.14" release exists
The major versions of DIALux (lighting design software) are:- DIALux 4.x (classic version, discontinued)
- DIALux evo (current main version, started around 2012, now evo 12 / 13)
- There is no widely recognized version 3.14 in the official release history.
-
Possible interpretations
You might have meant: Dialux 3.14- DIALux 4.13 (a later build of the classic 4.x series)
- DIALux evo 3.14 (a specific update build — but evo versions are numbered differently)
- A typo for DIALux 4.12 or 4.13
- A fictitious or internal version number
-
What would a paper on this cover?
If you are looking for a sample academic paper structure about DIALux in general (e.g., for a lighting design or simulation course), I can provide that — but not for a nonexistent "3.14" release.
4. Street & Floodlighting Wizards
Dialux 3.14 had a legendary "Street Lighting Wizard" and "Floodlight Calculation" wizard that produced compliant EN 13201 reports instantly. The evo version buried these wizards deep in menus. Many municipalities still accept 3.14-generated street plans. Dialux 3
2.1 Calculation Engine
- Method: Radiosity with hybrid rendering (deterministic and stochastic components).
- Output: Illuminance (lux), luminance (cd/m²), glare rating (UGR, DGI), and daylight factor.
- Accuracy: Compliant with CIE (International Commission on Illumination) standards for indoor and outdoor calculations.
Part 7: Limitations – Where 3.14 Falls Short
To be balanced, one must admit the flaws of Dialux 3.14.
- No Real-Time Rendering: You have to click "Calculate" and wait. No interactive relighting.
- Limited Complex Geometry: You cannot import a Revit model or a high-poly SketchUp file. It chokes on curved glass facades.
- No V-Ray or Photorealistic Materials: The renders look like 2010 video games (flat, bland, but technically accurate).
- Support is Dead: DIAL GmbH will laugh if you email them a 3.14 support ticket. You rely on legacy forums (Dialux-Forum.de archive) and Discord groups.
