Revit ies files lightning

Hello,

I’ve got a problem with lighting in enscape /revit. I can not get it like it should be in real life.

Is it normal that i have to manually adjust the initial intensity to 60000lm to see a little light only when i put the artificial light to 200%. No other lightning is on.

In real it’s a lamp of 60w producing +/- 6000lm…who give more light in real life than i can see on the render. I want to produce a interior render with only artificial lights to get a “warm” feeling.

Do is miss something ?

Thank you for your answers.

grtz
