Check at RDNA in the free area.  There are lots and lots of free light sets.

I don't think you need any particular light set to check your textures with....just something that lights up the scene in a pretty neutral way.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
