I'm looking for freeeware for adding lights and some basic rendering. Dont really want 30 day trial ones.

Try Podium – the free version doesn't expire but you can't directly export high res images. Depends what you want it for – if screen grabs are OK then you're in business.

I find LightUp more intuitive to use but the trial version for that is time limited.

There's a free version of IDX Renditioner, limited to low res output I think but should be fine for trying things out.
