Hi everyone, I wonder if there is a relation between cycles light intensity numerical value and some phisical unit. Just like linear distance units (1 BU = 1 m) I wonder if they used some convention like intensity 1 is 1 cd/m2 for area lights. So if i model a light bulb and assign an emission shader with the same intensity of the real thing i can get plausible and coherent light intesity in a scene. Same for sun lamps (maybe lux are more appropriate for this kind of light).
Thanks in advance!
