Lighting design calculator

Lighting Design Calculator

Choose the space type and room size, then use sensible UK defaults for lux level, ceiling height, fitting count, installed load and product range before detailed lighting design.

Share the application, site size and any ceiling or product constraints. Lumenloop can turn the calculator output into a project pathway.

Project brief

Set the planning assumptions.

The calculator uses real Lumenloop range data where output and wattage are available.

Application Sets the recommended lux level, typical ceiling height and product logic.

Area m2 Approximate lit floor area.

Ceiling height Select an application to fill the default height. Each space type uses a planning-average ceiling height, then you can overwrite it with the real site dimension.

Colour temperature 2700K is included for warmer hospitality, bedroom, lounge and feature-area schemes where the selected range supports it.

Preferred fitting path Default office recommendations show panel and downlight packages first, with limited alternatives.

Specification priority

Controls

Emergency

Early-stage output only. Final specification still depends on layout, reflectance, ceiling detail, spacing, glare, optics, emergency provision and control strategy.

Calculated result

Ready when the brief is set.

Enter the project assumptions, then press Calculate Fit to generate the output profile.

Primary product fit

No result has been calculated yet.

Select an application first.

Once a valid application is selected, the calculator fills the typical ceiling height, product path and visual result panels automatically.

Adjusted lumen requirement

Recommended lux multiplied by area, adjusted for early-stage utilisation.

Approximate fittings

Rounded up against the primary model output.

Installed load

Based on the selected model wattage.

Spacing guide

Indicative centres if fittings were distributed evenly.

Room count visual

Dots appear after an application is selected.

Common product ranges for the brief.

The selection is weighted toward the space type, typical mounting height and the product ranges most likely to be specified.

Compare All

Built-in assumptions

Use the right space baseline before selecting the fitting.

Office

Uses a 500 lux workstation baseline and 2.5 m as the office planning average when the project height is unknown.

Retail

Uses a 500 lux shop baseline, a 3.2 m planning-average ceiling height and favours spotlights or downlights before linear ranges.

Hospitality

Uses a 300 lux ambient baseline and 2.7 m as a balanced average across reception, corridor and amenity spaces.

Education

Uses a 300 lux teaching-space baseline and 2.7 m as the classroom/training-room planning height.

Circulation

Uses a 150 lux calculation baseline and 2.4 m as the practical corridor starting height.

Washroom

Uses a 200 lux protected-area baseline and 2.4 m as the compact-service-space planning height.

Warehouse

Uses a 200 lux general warehouse baseline, a 6.0 m low-bay planning height and robust high-output fittings.

The calculator generates an enquiry pathway with area, baked-in recommended lux, ceiling-height assumption, output load, suggested product range and model code. Use it as the starting point for a project review.
