The light on the front side get weaker if more back material is mixed with it. Other Transparency color will mix it with Vray 2 Sided Material (2 Sided Material in the image above) in the Front material slot. Black Transparency color in that main 2 sided material ensures that the back side is as bright as possible. With Transparency color in Vray2SidedMtl (2 Sided Material in the image above) in the Front material slot you can adjust the mix between the front and the back material, but then the back material in the main VRay 2 Sided Material (Front/Back Material in the image above) is override by any material in the Back material slot. I added another Vray 2Sided Material to the Front material slot. I have found the way to fix that problem.

QUESTION: How to adjust the brightness of external side and not loose the brightness of the internal side? Internal side doesn’t represent the nature at all. VRay 2SidedMtl – Transparency: WHITE – material reversed. VRay 2SidedMtl – Transparency: GRAY – Front and Back materials mixed. VRay 2SidedMtl – Transparency: BLACK – material not reversed. Images below explain how this material works and what had happened. My light shade with 2 sided material reversed was darker inside than on outside. I was trying to use this material on the light shade and I’d found a problem when the second side of the material was also visible. The trick is to use Vray 2 Sided Material with properly adjusted transparency (usually texture map on refraction layer) There is a great tutorial at blog about how to create realistic curtains.
