Guessing at light levels causes problems

Calculations that give you certainty

Using professional software like DIALux, we model your space and calculate exactly how much light you'll get from a proposed scheme. The result is documented proof that your lighting meets requirements — and confidence that it will actually work.

  • Uniformity analysis
    Verification that light is distributed evenly, without dark spots
  • Layout drawings
    Showing fixture positions on plan
  • Lux level calculations
    Documented illuminance for each area of the project
  • Compliance verification
    Checked against relevant standards (EN 12464, CIBSE, UNE)
  • Product specification
    Fittings selected to meet calculated requirements
  • Technical reports
    Formatted for planning submissions and building control

Standards we calculate against

  • European standards

    • EN 12464-1 — Indoor workplace lighting
    • EN 12464-2 — Outdoor workplace lighting
    • EN 1838 — Emergency lighting requirements
    • EN 13201 — Road and public area lighting
    • UNE — Spanish national standards implementing EN requirements

  • UK standards (for cross-border projects)

    • CIBSE Lighting Guides — UK standards for various building types
    • BS EN 12464-1 — Lighting of indoor work places
    • BS 5266 — Emergency lighting for escape routes

Who needs lighting calculations

  • Commercial projects

    Offices, retail, healthcare, education requiring documented compliance

  • Architects & Designers

    Technical backup for lighting proposals in planning submissions

  • Developers

    Evidence of code compliance for building control

  • Facilities Managers

    Verification that existing installations meet current standards

  • Anyone

    Wanting confidence that their lighting will actually perform as expected

How it works

What the report includes

  • Lux level results
    For each room or area
  • Uniformity ratios
    Detailed analysis
  • Layout drawings
    Showing fitting locations
  • Product schedule
    With quantities and positions
  • Summary compliance statement
    Verification for sign-off
  • Technical data
    For specified products

The result

Documented evidence that your lighting scheme meets requirements. Confidence for sign-off. Technical backup for planning submissions. And assurance that the finished space will have the light levels people need.

FAQs

Do I need calculations for a residential project?

Not usually required by regulation, but they can be helpful for larger spaces or where you want certainty about light levels before ordering products.

How long do calculations take?

Typically 3-5 working days from receiving floor plans, depending on project size and complexity.

Can you calculate for a scheme someone else has designed?

Yes. We can verify that a proposed scheme meets requirements, or identify adjustments needed to achieve compliance.

What file formats do you need for floor plans?

PDF or DWG/DXF are ideal. Clear scanned drawings work too, provided dimensions are legible.
