Light volume (Lux or FC) to solar intensity (W/m2) conversion
- Bright sunlight is approximately 136000 lux = 1075 W/m2. The factor changes slightly depending on time of the day, condition such as cloud cover, moisture in the air etc.

Calculator (Light Calculator)

Count light space needs based on the area type and size (Lumens)
Count number of bulbs needed to light the area (Information on the number of Lumen of the bulb can be found on the packaging)
Lumens measure how much light you are getting from a bulb. More lumens means it’s a brighter light; fewer lumens means it’s a dimmer light. Lumens let you buy the amount of light you want. So when buying your new bulbs, think lumens, not watts.
A typical household light bulb might emit anything between 300–1000 lumens, while a high-powered floodlight could emit in excess of 20,000 lumens.
