General Disclaimer

The information provided by Luminosit (“https://www.luminosit.com”) is for general informational and educational purposes only. We share it in good faith, but we make no warranty of any kind about the accuracy, completeness, or suitability of anything on the site for your particular room, fixture, installation, or budget.

Any use of the calculators and content is at your own risk. It is your responsibility to confirm that a result fits your specific circumstances — and that any electrical work is safe and code-compliant — before you rely on it.

Estimates, Not Professional Advice

Luminosit’s tools produce educational estimates from the numbers you enter and standard photometric formulas. They are not professional electrical, engineering, lighting-design, safety, financial, or energy advice, and they do not replace a site survey or a proper design. Photometry converts and predicts light on paper; a real installation involves wiring, fixtures, controls, walls, and people. Before you carry out electrical work, specify lighting for a workplace or other safety-critical space, or commit money based on an energy estimate, have the plan checked by the appropriate qualified professional.

Who to Consult

For decisions that affect safety, compliance, or significant cost, consult the right professional rather than relying on a calculator:

• Electrical work: a licensed electrician for wiring, circuits, loads, and anything connected to mains power, working to the relevant electrical code.
• Lighting design & compliance: a qualified lighting designer or engineer for workplace, emergency, and safety lighting, and for meeting the applicable illuminance standards and building regulations.
• Energy & cost decisions: a suitable professional for large retrofit or investment decisions, since real savings depend on your tariff, usage, and equipment.

Why Results Vary

Actual outcomes can differ from an estimate because of:

• Room and surfaces: wall, ceiling, and floor reflectance, room shape, and obstructions change how much light reaches a surface.
• Fixtures and losses: luminaire efficiency, light-loss and maintenance factors, mounting height, spacing, and beam angle all reduce real-world illuminance below the ideal figure.
• Product variation:a lamp’s rated lumens, efficacy, colour temperature, and colour rendering vary by brand, batch, and age.
• Your inputs: the wattages, dimensions, distances, prices, and hours you enter, along with units and rounding, all change the result.

A Note on Lumens, Lux, and Candela

These quantities describe different things and are easy to confuse. Lumens measure total light output; lux measures how much of that light lands on a surface (lumens per square metre); and candela measures luminous intensity in a particular direction. Converting between them relies on assumptions — a beam angle, a distance, an area, a uniform distribution — that rarely hold exactly in a real space. Treat a converted figure as a guide, not a measurement, and use a calibrated light meter when an accurate value matters.
