I got this kit about a month ago:
Rigid Industries 98000 SR-M Diffused Back-Up Light Kit https://www.amazon.com/dp/B00FS82Y4O..._OVpNwbBNCMVVK
It had everything I needed to get it all set up, and everything was very high quality. The only thing that I didn't like about this set up is that the reverse line that needs to go from one of your reverse lights (or the 7 pin connector) isn't in the loom. We ran a snake and put it in the loom though.
As back up lights I couldn't imagine needing more light (I have 15% tint on the front, and rear windows and back glass have 5%) I can see clearly out of those windows.
I've used it a few times when I needed light behind my truck (loading things in the back, field dressing and quartering a deer extra.) and it provided plenty of light, i don't think the extra 50 bucks will do as much as you want them to do.
