Is there a way to enlarge the working 'radius' of a point light? I would expect some attenuation factor controlling that or maybe a 'field' like a magnet has.

Current 'fixed' working radius is very small.

Not yet - it's annoying. You could feature request it (make a bug report amd select feature from the severity drop-down) but I'm pretty sure modifications ahave already been requested.

I'll do that. More calls will add weight.

Attached Link: done.

200% is the limil! It's an aggrevation!

Further increasing intensity is not the solution in a 3-D virtual world. Your eyes in real world can handle huge differences in light intensity because they work to a log scale. Shader computations work linear and you may wash out the rest by going too intense. It's the attenuation rate that needs to be controllable.

You can take the intensity higher than 200% by double-clicking the label of the Intensity slider and turning off Respect limits (or raising the max value allowed). However, as bagoas says that's of limited use - we need to be able to adjust the falloff or cap the intensity (which was done in ealy beta builds by some users hacking the shader script - I don't think anyone's tried it since the scripting kit was released).
