How It Works
Workspace Lux helps you estimate practical lighting requirements without complex lighting design software. Enter your room or desk dimensions, choose a workspace type, and get estimated lux, lumens, and LED wattage in seconds. All calculations run in your browser — no account required.
- 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.
Workspace Lighting Basics
Why workspace lighting matters
Good lighting reduces eye strain, supports focus, and makes video calls look professional. Too little light forces your eyes to work harder; too much causes glare on screens and paper. Workspace Lux focuses on the numbers that matter for everyday planning: how bright your desk should be, how many lumens a room needs, and what LED wattage to expect.
Lux vs lumens vs watts
Lux measures illuminance — how much light lands on a surface per square meter. Lighting standards and comfort guidelines usually speak in lux. Lumens measure total light output from a lamp or fixture. Watts measure electrical power; with LEDs, the same lumens can be produced with far fewer watts than old incandescent bulbs. To plan a room, start with a target lux, multiply by area to get lumens, then divide by LED efficiency (lm/W) for wattage.
Recommended lux levels for workspaces
General office work typically targets 300–500 lux. Detailed tasks such as design review or inspection may need 750–1000 lux. Meeting rooms and reception areas often use 300–400 lux for a softer feel. Home office desks usually aim for 300–500 lux on the work surface, depending on whether you mostly use a monitor or also read paper documents.
| Space | Typical lux | Notes |
|---|---|---|
| General office | 300–500 | Computer and paperwork |
| Meeting room | 300–500 | Presentations and discussion |
| Design studio | 750–1000 | Detail and color work |
| Home office desk | 300–500 | Focus and video calls |
Choosing the right color temperature
Color temperature is measured in kelvin (K). Warm white around 3000K feels cozy and works well in home offices. Neutral 4000K is the corporate office standard — alert but not harsh. Cool 5000K suits design studios, labs, and video setups where color accuracy matters. Avoid mixing very warm and very cool sources in the same field of view.

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.
