Your "GC Light" is nothing more than an ordinary light with an intensity of 50%.

You can't GC a light. All you did was making it stronger, via some very complicated math resulting in a constant.

The Simple_Color with the white chip is a 1.

The next node, Math:Pow (2.2), has no effect on the number 1. 1 to any power is still 1.

Then you multiply it with .8, giving .8.

Color_Math_3:Add is adding white to that, producing 1.8.

Next is Color_Math_2:Pow (1/2.2) producing the number .818181.

You're running that into the Color chip (white). White being equal to 1, the color is .818181.

The intensity is .6, so the resulting luminance of the whole chain is .490909, or roughly 50%.

After all is said and done, the light is a white 50% intensity.

Then you disconnect it all and changed intensity to 20%. Of couse it looks darker.

Change to 50% on the ordinary light shader and it will be the same.
