[Bldg-sim] question regarding lighting efficiency/gains units of measurement

[Christian Stalberg]

In Europe one sees W/m2-100 lux as a measure of lighting related gains or lighting efficiency. What is the equivalent here in the states? I suspect it is a messy conversion.

 

Thank you in advance.
