Photovoltaics
- 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.
- Real time light volume graph
- Light recording
Lightmap
- Create a room Lightmap – The light intensity map is used to check where the light is strongest and where the light is low

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.
