Office lighting calculator for UK workplaces

Default assumptions give an early answer; the office area, ceiling height, daylight and fitting output can be adjusted where they change the lighting requirement.

This sets the recommended light level automatically so the user does not need to know it.
Approximate office floor area.
2.7 m is a practical UK office default; adjust if the ceiling is known.
Adjusts the artificial lighting allowance.
Use a typical panel or linear fitting if unknown.
Allows for light loss over time. Lower factors need more initial lumens.
Early-stage guide only. Final office specification still depends on layout, reflectance, ceiling detail, glare, optics, emergency provision and control strategy.

Indicative fittings
--

No result has been calculated yet.

Office lighting results will appear here after calculation, including recommended lux, maintained lumen requirement, indicative fitting count and spacing guide.
Recommended target --

Set from the selected office context.

Light required --

Area, recommended light level and ceiling-height allowance.

Indicative fittings --

Rounded up from the entered fixture output.

Spacing guide --

Indicative centres for an even layout.

Lighting guidance

What the result means.

The calculated guidance will explain the recommended light level, maintained lumens and approximate fitting count.

Maintenance factor --

Included in the lumen requirement.

Ceiling allowance --

Higher ceilings need more delivered lumens.

Daylight allowance --

Adjustment based on natural light selection.

Reference targets
Office baseline before fitting selection.
Desks

Workstation areas commonly start around 500 lux, with careful review of screen use, glare and uniformity.

Meeting

Meeting rooms often need comfortable general lighting, flexible controls and a scheme that can support presentation use.

Support

Breakout, reception and circulation zones can use lower targets, but should still coordinate emergency provision and controls.

Products

LED panels, linear luminaires, downlights and suspended fittings should be checked against ceiling type, UGR requirement and the office layout.

Controls

Occupancy sensing, daylight dimming and DALI or Casambi control can change both the running cost and the way the workplace is used.

Specification support

Review the office requirement with Lumenloop.

The calculator produces office enquiry details with area, recommended light level and output load for early product selection.

Each calculated product card leads with a quotation request, carrying the office lighting estimate into product information, options and quotation detail.

Use the result as a first pass for office lighting design, then compare LED panel lighting, linear lighting, commercial downlights, UGR19 office lighting and the lighting colour temperature visualiser where the workplace feel needs to be checked.
