How Our Calculators Work
WorkspaceLux helps you estimate practical lighting requirements without complex lighting design software. Calculations are based on room area, target lux, fixture efficiency, and usage hours. All inputs are processed locally in your browser — we do not store your data.
- Pick a calculator for your space (office, desk, or unit conversion).
- Enter dimensions and select your task or workspace type.
- Review lumens, wattage, color temperature, and fixture suggestions.
- Use the result as a planning baseline before buying fixtures or talking to a contractor.
Results are simplified estimates for general planning. Actual lighting performance depends on ceiling height, fixture type, room reflectance, layout, maintenance factors, and installation conditions. For commercial projects, consult a qualified lighting designer or electrician.
Frequently Asked Questions
What is the difference between lux, lumens, and watts?
Lux measures how much light reaches a surface (illuminance). Lumens measure total light output from a source. Watts measure power consumption. For workspace planning, you typically start with a target lux level, convert to lumens using room area, then estimate LED wattage from lumens per watt.
How many lux do I need for office work?
Most general office tasks work well at 300–500 lux. Detailed work, design, or inspection tasks often benefit from 750–1000 lux. Meeting rooms and reception areas may use lower levels for comfort.
What color temperature is best for a workspace?
Neutral white around 4000K is a common choice for corporate offices. Home offices often feel more comfortable at 3000K–4000K. Design studios and video setups may prefer 4000K–5000K for color accuracy and alertness.
Are these calculators accurate enough for professional lighting design?
These tools provide simplified estimates for planning and budgeting. Final lighting design depends on fixture distribution, ceiling height, reflectance, glare control, and local standards. Consult a qualified lighting professional for critical projects.
How do I convert lux to lumens?
Multiply your target lux level by the area in square meters: lumens = lux × area (m²). For example, 500 lux over 20 m² requires about 10,000 lumens.
