Some anomalies in Carrara's lights behavior that need to be fixed, or am I the only one to consider them as anomalies?

1. A bulb light has a range, a range fall-off, but has no fall-off type (Linear, inverse squared or logarithmic). Is this an omission or or is it the way a bulb light should behave?

2. A tube light emits light from both its ends. This isn't how tube lights behave in real world. Is this the way tube lights are supposed to behave in 3D world or is it an implementation shortcoming?

3. Disc and rectangular shape lights emit light from both sides. The also emit light from their periphery. I believe I saw in a demo of Cinema4D that their shape lights emit light from one side only, which is the behavior I would personally expect from a shape light.

Correcting these issues (if indeed they are issues) shouldn't take more than a couple of days and they would make Carrara's lighting so much more accurate.
