I don't have the pack.

I usually make my own lights from scratch, or sometimes I will see a set of lights that are essentially what I'm looking for and will tweak them to fit my needs.

The light set you point out is by Mec4D and she really does know her lighting, so I have no doubt that the lights would be excellent.

However, keep in mind that there is no such thing as "generic" lighting that will fit all scenes and moods.  IMHO it's best to spend the time learning how to create your own lighting, that way you can personalize and individualize the lights for each scene that you are doing.

Here is a thread about lighting. It contains all kinds of links to tutorials, discussions and help threads where good advice and information is given.

Lighting isn't something you can sit down and master, if that's even possible, in one sitting. It takes time.  I think it was December 2006 when i decided that I seriously needed to learn lighting and I spent 3 months fiddling around in Poser just with lighting. I would open lights and see what the person had done, I would tweak what they had done to see how things changed in the scene with various settings, and I would try creating my own from scratch.  Was it boring? You bet!  But while there is still a whole lot I need to learn about it, I have the basics down enough that now I can make my own lighting for each of my scenes  and when in doubt I post and ask for more information.

So far as buying those lights, it's entirely up to you.  It might be a good starting point for you to open them up in Poser and examine how she went about creating them etc.  It might get you on the right track to making your own.
