changing unit scale in preferences will affect light scale

[ANDREW_LEUNG]

I have a problem in VRay for Maya where if I change the unit scale (from inches to feet), suddenly all my VRay physical lights gets completely whack. Is this normal??

Hi,

Yes, this is normal.
To compensate for the change in the scene unit, you'll have to change the value of the Photometric light scale.
This attribute can be edited in the Render Settings->VRay->Misc->Photometric light scale.

In addition to that, it was requested a number of times to add a separate setting for the scene units as interpreted by V-Ray specifically so we'll get there.

Best regards,
