Free calculation. No sign-in. No selector journey.
This public calculator does not recommend a manufacturer, catalogue item or equipment model. It sends declared inputs to the protected Adelphos calculation service and never falls back to browser arithmetic.
No account or Adelphos project is required. No HTML report is offered. The downloadable report is the Adelphos-branded PDF returned by the protected report service.
How does the Lighting Lux Calculator work?
Use the room dimensions, target illuminance, luminaire lumens, utilisation factor and maintenance factor from the lighting brief and verified product data.
What the Lighting Lux Calculator calculates
The Lighting Lux Calculator uses declared design information to calculate luminaire quantity and maintained illuminance. Enter the real project inputs, review the result and download an Adelphos-branded PDF report.
Design information you need
Use the room dimensions, target illuminance, luminaire lumens, utilisation factor and maintenance factor from the lighting brief and verified product data.
Calculation result and PDF report
The result estimates the fitting quantity and maintained lux level for the stated inputs. Layout, uniformity, glare and emergency-lighting checks remain separate design tasks. A successful calculation can also produce an Adelphos-branded PDF report.
Checks, limits and responsibility
This calculation is an aid, not a design approval. The user must verify every input, applicable standard, result and its suitability for the project.
How to use the Lighting Lux Calculator.
The calculation follows four clear stages: gather verified information, enter the design inputs, calculate, then review the returned checks and report.
1. Gather the source information
Use the room dimensions, target illuminance, luminaire lumens, utilisation factor and maintenance factor from the lighting brief and verified product data.
2. Enter the design inputs
Use consistent units and declare every required assumption. This calculator does not silently replace missing required values with convenient engineering defaults.
3. Run the protected calculation
Submit the form to the Adelphos calculation service. The calculation performs no fallback arithmetic in the browser and returns only the public result needed for review.
4. Check the result before use
The result estimates the fitting quantity and maintained lux level for the stated inputs. Layout, uniformity, glare and emergency-lighting checks remain separate design tasks. Check the result against the coordinated design, current project requirements and competent-person review.
